Why Horizontal Drilling Results In A Lucrative Texas Oil Investment

Can investing in a more costly form of drilling mean better returns? Yes, if drilling for oil is performed utilizing horizontal drilling. Oil drilling technology has advanced a tremendous amount over the last quarter of a century. And while some people talk of the long-lost “good ole’ days” of oil drilling in Texas, Texas oil investment is still a possibility with horizontal drilling.

Enhanced Oil Recovery Paves Way to Future Extraction Methods

With rising prices for each barrel of oil, oil and gas investing is becoming more and more appealing. Especially with the newer enhanced oil recovery (EOR) systems in place that were not available even a decade ago.

EOR is an improved oil recovery system that uses techniques aimed at extracting more oil from a reservoir that cannot be achieved by direct drilling. One of those techniques is horizontal drilling, which can extract up to 60% or more of an oil reservoir, compare to only 20%-40% using traditional vertical drilling.

Now your Texas oil investment can reap big rewards with a company that practices horizontal drilling. Horizontal drilling uses coil tubing rather than 30-foot sections of steel pipe used on traditional wells. The coil tubing allows the drilling angle to be much more flexible, even drilling at angles of 90 degrees to 95 degrees. And rather than spinning the steel tubing to turn the drill, coil tubing techniques send high-pressure drilling mud through the tube which in turn triggers a pressure-sensitive hydraulic motor that rotates the drill bit.

It's Not Just Where you Drill - The Angle Can be Critical

Controlling the angle at which the drill bores into oil reserves is the key. Direct vertical drilling greatly reduces the exposure to the oil reservoir. Crude oil tends to accumulate within pockets of layered rock, usually sandstone. And because crude oil moves extremely slowly a direct tap from a vertical drill tends to produce low tap.

However, since horizontal drilling allows can access a crude oil reserve from the side, the total exposure to the entire reservoir is greatly increased, resulting in much more and faster oil recovery. In addition, horizontal drilling can access more than one pocket of crude oil. That means instead of drilling multiple vertical wells, only two or three horizontal wells may be needed to tap an entire oil field.

In addition, natural gas can now be collected from crude oil drilling using a process that converts the gas into a liquid state. Where once natural gas was burned off from crude oil production wells, it can now be harnessed and turned into a usable product.

Texas oil investing is at a new milestone. It is now possible to tap into wells that were once unreachable, and extract more crude oil than ever possible. If you are interested in oil and gas investing, now is the time to look into what could be a very profitable venture. Be sure you analyze the risks and benefits of oil and gas investing, and find a reputable oil company to invest in that meets your investing objectives.(ArticlesBase SC #1873355)

Introduction to Geothermal Energy

Our earth's interior - like the sun - provides heat energy from nature. This heat - geothermal energy - yields warmth and power that we can use without polluting the environment.

Geothermal heat originates from Earth's fiery consolidation of dust and gas over 4 billion years ago. At earth's core - 4,000 miles deep - temperatures may reach over 9,000 degrees F.

The heat from the earth's core continuously flows outward. It transfers (conducts) to the surrounding layer of rock, the mantle. When temperatures and pressures become high enough, some mantle rock melts, becoming magma. Then, because it is lighter (less dense) than the surrounding rock, the magma rises (convects), moving slowly up toward the earth's crust, carrying the heat from below.

Sometimes the hot magma reaches all the way to the surface, where we know it as lava. But most often the magma remains below earth's crust, heating nearby rock and water (rainwater that has seeped deep into the earth) - sometimes as hot as 700 degrees F. Some of this hot geothermal water travels back up through faults and cracks and reaches the earth's surface as hot springs or geysers, but most of it stays deep underground, trapped in cracks and porous rock. This natural collection of hot water is called a geothermal reservoir.

In the United States there are enough geothermal power plants to generate electricity and power for three and a half million homes (two thousand seven hundred megawatts).

How We Use Geothermal Energy Today:
 
Today we drill wells into the geothermal reservoirs to bring the hot water to the surface. Geologists, geochemists, drillers and engineers do a lot of exploring and testing to locate underground areas that contain this geothermal water, so we'll know where to drill geothermal production wells. Then, once the hot water and/or steam travels up the wells to the surface, they can be used to generate electricity in geothermal power plants or for energy saving non-electrical purposes.

In geothermal power plants steam, heat or hot water from geothermal reservoirs provides the force that spins the turbine generators and produces electricity. The used geothermal water is then returned down an injection well into the reservoir to be reheated, to maintain pressure, and to sustain the reservoir.

There are two types of power plants: a Flash Steam Power Plant and a Binary Cycle Power Plant.

Flash Steam Power Plant:

Flash steam plants are the most common type of geothermal power generation plants in operation today. They use water at temperatures greater than 360° F (182° C) that is pumped under high pressure to the generation equipment at the surface. Upon reaching the generation equipment the pressure is suddenly reduced, allowing some of the hot water to convert or "flash" into steam. This steam is then used to power the turbine/generator units to produce electricity. The remaining hot water not flashed into steam, and the water condensed from the steam is generally pumped back into the reservoir.

Binary System:


In the Binary system, the water from the geothermal reservoir is used to heat another "working fluid" which is vaporized and used to turn the turbine/generator units. The geothermal water, and the "working fluid" are each confined in separate circulating systems or "closed loops" and never come in contact with each other. The advantage of the Binary Cycle plant is that they can operate with lower temperature waters (225° F - 360° F), by using working fluids that have an even lower boiling point than water. They also produce no air emissions.

Is It A Viable, Long-Term Solution For The Future?

Environmental Issues:

There are little to no emissions

Geothermal power plants, like wind and solar power plants, do not have to burn fuels to manufacture steam to turn the turbines. Generating electricity with geothermal energy helps to conserve nonrenewable fossil fuels, and by decreasing the use of these fuels, we reduce emissions that harm our atmosphere.

It is environmentally friendly

Geothermal installations don't require damming of rivers or harvesting of forests -- and there are no mine shafts, tunnels, open pits, waste heaps or oil spills.

Technological Issues:

The power plants are reliable

Geothermal power plants are designed to run 24 hours a day, all year. A geothermal power plant sits right on top of its fuel source. It is resistant to interruptions of power generation due to weather, natural disasters or political rifts that can interrupt transportation of fuels.

The power plants have flexibility

Geothermal power plants can have modular designs, with additional units installed in increments when needed to fit growing demand for electricity.

Geothermal energy can be extracted from anywhere there are hot spots, U.S. to Third-World

Geothermal projects can offer all of the above benefits to help developing countries grow without pollution. And installations in remote locations can raise the standard of living and quality of life by bringing electricity to people far from "electrified" population centers.

Thousands more megawatts of power than are currently being produced could be developed from already-identified hydrothermal resources. With improvements in technology, much more power will become available.

Usable geothermal resources will not be limited to the "shallow" hydrothermal reservoirs at the crustal plate boundaries. Much of the world is underlain (3-6 miles down), by hot dry rock - no water, but lots of heat. Scientists in the U.S.A., Japan, England, France, Germany and Belgium have experimented with piping water into this deep hot rock to create more hydrothermal resources for use in geothermal power plants.

As drilling technology improves, allowing us to drill much deeper, geothermal energy from hot dry rock could be available anywhere. At such time, we will be able to tap the true potential of the enormous heat resources of the earth's crust.    (ArticlesBase SC #171771)

What are the Alternatives to Petrol?

The price of a barrel of oil is reaching new heights on a daily basis and pricing analysts forecasting that consumers can expect prices to rise even further. The rising price of oil will flow on to the petrol pump. Lately the oil prices surged past $120 a barrel for the first time and there is nothing that business owners and consumers can do to lower the price of oil on the world market. As a result, companies have to look internally at ways they can reduce their dependency on oil products. That’s why the car industry has increased work on developing alternative fuels, as well as cars that are less petroleum dependant.



Hybrid Cars have gained popularity and several hybrid models have made their way on to the market, like the Toyota Prius, Lexus RX 400 and the Honda Civic Hybrid. Hybrid cars have a much better fuel economy than conventional vehicles as a result of their hybrid electric/petrol engines and as a result, they are the cleanest cars on road. The main propulsion comes from the internal combustion engine and the electric motor assist the engine, when the car is accelerating, climbing hills or driving at low speed. The hybrid cars do not need be plugged in for recharging, because they charge themselves while driving. The energy that is normally wasted during breaking and coasting is converted into electricity, which is then stored in a battery until it is needed by the electric motor. The only disadvantage is that Hybrid cars cost more than conventional cars, but this is soon recovered by fuel savings.


Another alternative to gas powered vehicles are flexible-fuel vehicles. These cars are designed to run on a mixture of petrol and ethanol. The drivers can use either fuel without causing damage to the car’s engine. This is because the engine of a flexible-fuel vehicle has been modified so that it can run on petrol or any mixture of ethanol and petrol. Ethanol costs less than petrol, but its fuel economy is lower. Furthermore overall costs are likely to be higher and it’s not easy to find, because not many gas stations offer ethanol. Although, government tax concessions have addressed the question of cost in Australia. Therefore it only makes sense to buy a flex-fuel vehicle if you know that there is a petrol station stocking the fuel in your area.


Fuel Cell Vehicles (FCV) probably won’t be on the market for the next 5 years or more, but it could represent a major breakthrough. The cars operate in a simiar way to electric cars, but instead of the batteries being charged by an external electric source, the FCV batteries create their own power via a chemical process using Hydrogen fuel and oxygen from the Atmosphere. There is a big environmental benefit in that the only by-product of the chemical reaction is water. Additionally, fuel-powered vehicles can be twice as efficient as similarly sized conventional vehicles.





Another alternative are the Liquid Petroleum Gas (LPG)


powered vehicles. It is a much cleaner alternative to other vehicle fuels such as petrol and diesel. The fuel efficiency is generally equal in comparison with petrol engines. The technology is mature and there is a good selection of LPG powered cars with many of the car manufacturers worldwide. Unfortunately, only a limited number of petrol stations stock LPG due to the large tanks that need to be installed. The countries with the largest number of LPG vehicles are Argentina, Brazil, Pakistan, Italy, Iran and USA. In Argentina almost 15% of all vehicles are LPG powered and they are the cabbie's vehicle of choice.

Hybrid cars, in the short term, are the best choice for the fuel and environmentally conscious, because they are already established in the market place. They are always more fuel efficient than conventional vehicles and are environmentally friendly. Even better for our environment, are Fuel Cell Vehicles, which are completely emission free. But the automobile industry needs to invest heavily in this fuel technology so that these cars can be put into serial production!!!

Car Hire companies are getting in on the act and many fleets around the world have Hybrid Cars to rent. DriveAway Holidays can supply a Hybrid car through companies like Hertz here in Australia and overseas. As more and more people become environmentally concious as well has being price sensitive, Hybrid cars will become more and more common.   (ArticlesBase SC #644921)

Before You Say The Gulf Coast Cannot Live Without BP

The older I get, the more I realize that in the cases of jobs and money, especially in today's economy, both can be very touchy subjects. Such is the case of mega-employer B.P. Aka British Petroleum.   At times, one knows if one speaks ones mind, feelings might be hurt.

I grew up just north of the Mississippi Gulf Coast and N.E. Of New Orleans. It meant the world to me and still means a great deal (Though I have lived in Arkansas for 11 years, I still have many friends…and family there); and my family of origin has been there four decades.

Before reaching a definite conclusion, I had to consider the following. B.P has consistently been one of the top-ten largest oil firms in the world, along with Shell, Exxon, Conoco/Phillips et al. But bigger is not always better. Whereas ALL of BP's competitors have had ten or less safety violations per year for several decades, BP has consistently violated those rules and had 250+ violations annually, putting lives, ways of life, wildlife, and economies at risk in pursuit of big money.

This time, in a flash, they snuffed out the lives of eleven men, (and two more died later in the clean-up), ruined countless 2-3 generation family businesses, the entire ecosystem, and with oil and dispersant everywhere, it is not if, it is WHEN a hurricane comes, will we will all see the scope of the damage done. Those tar-balls won't be sitting on the beach any longer. The oil will not be floating around only in the ocean. It will be in our schools, businesses, and homes, on our land-raised food, etc. 1.5 million gallons of dispersant has been used.  For whatever reason, BP chose one of the most toxic kinds. There are some that are harmless to the environment. They chose not to use those. The dispersant used stays on the ocean floor forever and is  a chemical toxin, many say much worse than the oil!

Anyone who has lived on or near the coast knows, a hurricane or major tropical storm WILL happen. It will be interesting to hear the feelings of those who are sure BP is our economic saving grace when the oil starts heading into the inland.

You may remember awhile back, under Florida's Republican Governor Jeb Bush, a very tough decision was made. Did Florida want offshore drilling or pristine beaches, fishing, wildlife,and a booming tourism economy, offshore drilling, or both? It wisely decided on the former.

There  remains no Florida offshore drilling, though they are seeing the results of what can happen when  an out-of-control corporation such as BP.

As I write this, there is a tropical storm forming in the Caribbean moving towards the Gulf.Again, we know this can turn easily into a hurricane, and, even if it stays a tropical storm, itwill bring much of what is in and on the ocean onto land, sometimes way beyond the Coast itself.

Did it ever occur to anyone that even if deep-water drilling returns, and BP is banned, thatany of the other top six, with near-pristine safety records, could easily take over and do it right after the clean up (though I would prefer to see no deep water drilling at all until all the snags are worked out).

We saw a BP spokesman on the news yesterday use the tired old analogy, "When an airplane crashes, they don't outlaw flying". Well that's a tired old analogy for a reason. It's not exactly true.  When airlines such as Eastern and several others had such consistently poor safety records and crashes that it finally did not have the money to safely fix, as large as the firm was, it eventually  folded or would have been violating more and more. They, unlike BP, knew the right thing to do before more destruction and deaths happened.

Did the airline industry suffer from that.  It did just the opposite. It learned from Eastern and others errors and, though it has never been that profitable except for a few airlines, improved its safety record dramatically.

My wife Lee brought up another really interesting issue. If deep water drilling (which is only10%  of ocean drilling) SOOO important for Louisiana, why is it that there is so much poverty there?  In Alaska for instance, every citizen is given a stipend for giving the opportunity of oil companies to drill. Surely much of Louisiana does not live in poverty, but given "just how important oil is for it to flourish", the track record is pretty bad. I see MANY more people in Louisiana getting benefits from technology, banking, arts, etc than oil.

I see a few oil fat cats taking in the cash from deep water drilling. Keep in mind only 30 or soof the 300 offshore La wells are deep-water.

The topic of offshore drilling came up again (in Florida), (not just  deep-water but ALL offshore drilling) under another Republican Florida Governor  Charlie Crist. He also, saw no benefits to the state and the state remains a flourishing  tourism and wildlife reserve.

I guess if I still lived and worked near the coast, it would be too easy to buy into BP's nonstop "Good-guy" PR campaign. It is nonstop and it seems to be effective.I know how easy it is to "overlook a problem or issue if it is nearby". It is human nature to "go into denial". But if one "who has been there", but now can see it from a distance, a new perspective, the whole issue becomes more clear.

One can see through the BP ad campaign's  thin-veneer. It is smoke and mirrors and very expensive. All those millions of TV dollars  could and should go to small business owners, wildlife refugees, out of work oil workers, etc., but no.

It is going to put on a happy face. Sorry BP. We have more than a junior high education; mos tof us, and we don't buy it. Any of it. Thank you for trying. Please stop while you are way behind, and let another oil company do the job.

I used to (try) to work in the entertainment industry. I had a few successes but many more failures than successes. Though it was an ego-blow to pack up my bags and leave NYC (and L.A.), I did so. Now I write songs, cartoons, articles, etc., am married, and very happy. When I left the exciting field of "showbiz", I had no idea what would happen next, but as  it turned out, it was better for me and everyone involved. Can't you do the same, BP with our oceans? You've had successes, but LOOK AT THIS FAILURE!!!!!

As far as us, victims of BP, this may be a real wake-up call. The alternative energy is out there.It is not expensive, and it is easy to convert. For years I have talked about "we should…" and"wouldn't  it be nice if…?" In other words I could talk the talk very well. Perhaps it is also time for ME to  look within and walk the walk; by actually using such alternative fuels. I can't change BP.

I  can write articles and songs that hopefully raise awareness. I can change me, and that means taking this issue seriously, very seriously, as I can see the horrendous damage this has done.     (ArticlesBase SC #2728569)

Solid Content in Drilling Mud

Solid content is a fraction total solid in drilling mud, and it always increased while drilling ahead because of drilling solid (cuttings), mud chemical additives and weighting material. When we talk about the solid content, we always mean soluble and insoluble content in the drilling fluid system.

There are three types of solid contents as listed below:

- Soluble material such as salt
- Insoluble high gravity solid (HGS) as weighting agents (barite, calcium carbonate, hematite, etc.)
- Insoluble low gravity solid (LGS) or drilled solid as particles from cuttings

The drill solids are the worst content in the drilling fluid because it gradually deteriorates mud properties. Moreover, if its particle size is less than 5 microns, they could not be removed by mechanical methods, and they will stay in the mud forever. Generally, thye will take 6-7 percent of total mud volume. Since the drilled solid content is very important, it must be checked daily. For good drilling practices, the drilled solid should be tested twice a day by retorting. The upper limit of the drill solid faction should be 6-7 % by volume or approximately 55 – 60 pound per barrels. Please remember that this figure is general rule of thumb. Practically, you can operate the drilling operation with more solid content for a while but over all performance will be gradually down.

There is another value besides the LGS and HGS that you must contemplate is the average density of solids in the drilling mud. I will explain why this figure is important and what it tells us. The weighting materials as barite, Calcium Carbonate, etc have a specific gravity value about 4.2. However, the drilled solids as clay and silt have a less specific gravity about 2.6. The average density means the relative concentrations of both the weighting agent and the drilled solid. Normally, the acceptable value of the average solid density is about 3.8 or higher. If you see this value below 3.8, it indicates that there may be too much low gravity solid in the mud.

The operational impacts of solid content are as follows:

Equivalent Circulating Density (ECD) – The ECD will be higher if the solid content increases, regardless of whether High Gravity Solid (HGS) or Low Gravity Solid (LGS). As you may know, excessive ECD will lead to formation fracture and a loss circulation issue.

Differential Sticking – The filter cake can be thick and sticky, if there are a lot of low gravity solids in the drilling mud. When there is thick mud cake, you will have high potential to get differentially stuck across permeable formations.

Rate of penetration – High concentration of the solid content will affect the overall rate of penetration. As you know, there are three solid contents added into the system. The first two contents are weighting material and chemicals which we really need them in the drilling fluid. For this part, we cannot reduce their content in the mud because they are essential to for mud properties. The last one is the drill solid that we are able to control by mechanical methods. Therefore, in order to optimum ROP, you need to control the amount of drilled solid in the mud.

Surge/swab pressure – The excessive surge and swab pressures are resulted from the high amount of solid contents in the fluid system.        (ArticlesBase SC #3934086)

Easiest Ways And Places To Purchase Crude Oil

There are lots of countries in the world that produces crude oil. These countries includes Nigeria, Mexico, Iran, Russia, USA, Saudi Arabia, Venezuela, Kuwait and the others.Finding Suppliers to purchase crude from should be the next step since you now know the countries that produces the largest quantity of crude in the world.

You could decide to start visiting the oil producing countries above to purchase oil and i must say it is not so easy. The United States of America today produces oil but also imports crude.Amongst all countries, the best and less- stressful place to purchase crude is Nigeria. Nigeria's crude also known as bonny Light is one of the world's best crude as it is not hard to refine and  contains very low sulfur content.Nigeria is such a big country as it drills millions of barrels every day. You can visit http://crudeoilservicing.blogspot.com  to get mandates that can get you crude oil  in Nigeria

Purchasing crude oil in Nigeria has always been good news  to investors and buyers as the regulations are not so tough or hard to meet.Nigeria has fewer restrictions guiding the exportation of petroleum. If you would like to purchase crude from  Nigeria, you would need to contact sellers. More so, to contact these sellers, you also would have to locate mandates that would act as an intermediary broker to connect you with genuine sellers. All sellers get their allocations from the NNPC.

Iran Censured By I.a.e.a

The Board of Governors of the International Atomic Energy Agency

I.A.E.A. passed a resolution to censure Iran for having built secretly uranium enrichment site, near the city of Qom, and asked to immediately freeze the project. The resolution, approved on overwhelming majority (25 votes to 3, with 6 abstentions) is the first in four years, by the body, in which representatives of 35 countries, and with the unusual support of Russia and China, and a clear message of international irritation for ayatollahs behavior. It is not clear, however, if vote, backed by the six powers of the so-called 5 +1 (the group that leads the negotiations with Tehran), we translate 'in the support of Russia and China to any new sanctions against Tehran.

Tehran's immediate reply: "The adoption of this resolution - said Ambassador Ali Asghar Soltanieh - Not only is ineffective for improving the current situation, but will undermine the environment production absolutely necessary for the success of negotiations in Geneva and Vienna, which should lead to a common understanding."

When I read such declaration I really feel that they are pulling our legs, thinking that they dealing with stupids.
In the statement released immediately after the vote, the Iranian diplomat said the resolution was a step "too hasty" imposed by a limited number of countries represented in the body of directors. U.S. envoy to the IAEA said that patience with Iran is running out "and that can not be 'continue round of talks that follow one after another, to no available. The resolution of censure Iran said the British Foreign Secretary, David Miliband, is "the strongest possible signal 'envoyed to Tehran. "The resolution approved today by the I.A.E.A. Board of Governors is the strongest possible signal to Iran that its actions and its intentions remain an issue of major international concern," it said in the Foreign Office statement.

RUSSIA warns Tehran. Iran must take seriously the IAEA resolution. It's the warning that Russia has turned the ayatollahs after approval by a large majority of a valid complaint against the government of Ahmadinejad. "We rely on the fact that Tehran will react 'with absolute seriousness' to the signals contained in the resolution," reads a note from the Foreign Ministry, "and ensure' full cooperation with the agency."
USA: I.A.E.A. decision means censuring the activities of the new nuclear site in Tehran and that was significant. This was announced a U.S. State Department official commenting on the new resolution approved by the governors of the agency in Vienna against Iran.

If Iranian Government thinks being in a position to globalize the war and its vision of the Muslims world by leading and channeling the sense of revenge of the fundamentalists against the Western Countries, I believe they have made the biggest mistake ever. After the fall of the Soviet Union, another collapse is forecasted: that one of Ahmadinejad and their illuminati advisors.

Military Insiders Alert President Obama That Israel Is Going to Strike Iran

President Obama has just received a notice co-written by multiple military and intelligence insiders warning him that an Iran War resulting from an Israeli strike on Iran nuclear targets is about to break out as early as this month unless he takes quick action to stop it.



The last time that a group of intelligence professionals warned a sitting president about the potential for war was in February of 2003, when George Bush Jr. was warned that he was surrounded by, "advisers clearly bent on a war for which we see no compelling cause."



Needless to say, the warning was concerning the country of Iraq, and we know that the Iraq War was not avoided.



Have we learned nothing from history?



Does the President have the desire to avoid additional bloodshed, or will he let the nation be blindly led to another war depending on questionable pretenses that benefits the couple of at the expense in the numerous?

With both the economy and also the President's approval rating sinking precipitously, war may prove to be an all-too-convenient distraction towards the economic troubles at property, especially if blame can be passed to Israel.



Will the President view an Israeli-induced conflict as an opportune event to grandstand and aggrandize against the war, so that you can boost his approval ratings and take the primary focus of Americans off the economy?



Do we seriously would like to trade higher Presidential approval ratings for our young men and women coming house in caskets?



This warning must not be taken lightly. The scenario is gravely serious, and also the individuals issuing the warning are of the highest of integrity and come from deep within the military and intelligence establishment. Some from the sources sounding the alarm include:



Ray McGovern, US Army Intelligence Officer, Directorate of Intelligence, CIA (30 years)



W. Patrick Lang, Col., USA, Unique Forces (ret.); Defense Intelligence Officer for Middle East/South Asia, Director of HUMINT Collection, Defense Intelligence Agency (30 years)



Phil Giraldi, Directorate of Operations, CIA (20 years)



Ann Wright, Col., US Army Reserve (ret.), (29 years); Foreign Service Officer, Department of State (16 years)



Hundreds of thousands, if not, millions of lives hang within the balance. Will the President heed the warning, or will he succumb to what President Eisenhower described in his farewell address as the "military-industrial complex?"



The warning is real.

The option is clear.

The President will choose. May perhaps he decide on wisely. (ArticlesBase SC #3148231)

KASHMIR DISPUTE –CONSPIRACY ROOTS IN AFHGANISTAN

KASHMIR DISPUTE –CONSPIRACY ROOTS IN AFHGANISTAN

BY PROF GHULAM MOHYUDDIN WANI

INTRODUCTION

 In our previous series on the topic we have narrated a few dates and events which made Kashmir an international issue. Here we shall discuss how the strings of the conspiracy are and were spread throughout the Indian sub content and beyond. Readers must envision the drug triangle, ineternational borders, and super power politics.Cold war, track 2 diplomacy and a shadow ghost politics operated by secret agencies behind the scenes. Here we describe the events involving India-Afgan-Russian and other networks operative in past. November, 1973. Khan wali khan on return visited Afghanistan and met Ameer Akbar Hyderi, AB.Qadir,Ajmal Khan KHATEK,Noor Mohd Taraki,and Sardar Mohd Dawood Khan.He met them many times to discuss the London plan of disintegrating Pakistan father and thereby annexing Azad Kashmir to Indian domain through deceit node proxy wars. Russian Afgan treaty of 1919

According to this treaty Russia stood guarantee to the existence of Afganistan. THE AFGAN SHAH HAD TO BE NEUTRAL. To disturb this articulation and breach this agreement an attempt to have a revolt against SHAH ZAHIR SHAH WAS SET INTO ACTION. Shah having respect to the treaty was not in compromising mood with the conspirators mostly masterminded by Russian and Indians.

Thererefore in the night of 16-17th July,1973 at 2PM LEGITIMATE King of Afghanistan was dethroned and Sardar Dawood took over as military dictator. It was a communist run conspiracy to enforce destructive forces on western borders of Pakistan, a step towards weakening Pakistan defences. Sardar Dawood had remained the prime minister of Afghanistan from 1953-63 and has communist back up along with administrative officials of his time. This coup was well designed that shah had to take refuge in west and many of his supporters became migrants in west. I have the occasion of meeting a few in Hannover Germany around 1982 collecting medicine for the uprising against Russian occupation later, when Dawood failed and Russians invaded the country.

 The period of 1955-65 was a period of tussle between Capitalist backed Pakistan and Russian backed AFGANISTAN The last relationship was DOMINATED by RUSSIAN Afgan TREATY. Thus the cold war days run like flowing waters across the continent ,result into wars of 1965,1971 and Russian invasion and occupation of Afganitan.It followed by USSR falling apart and a new force Mujahedeen supported and financed by West especially USA.

This gave birth to Muslim uprising to deter exploitation by the two blocks. This is where the birth of terror took place partly to revenge the conspirator and partly the realization that Muslims are targeted and massacred all around the globe be it be in Phalestien,Kashmir,Afganistan,yogosalvacia,sudan,Somalis and many other places. The realization that the Muslim resources of oil are used by the west and communists too to kill them and weaken them both physically, materially and financially.Monarcy, dictators were preferred over elected or selected representatives by the so called democracies to take undo advantage.


ERA OF COLD WAR BETWEEN Afganistan and Pakistan in 1960s

The Russian influence in Afghanistan and American permutation in Pakistan saw two Muslim neighbours as enemies. The ports of Pakistan closed to Afghans and coincided with Iranian borders and waters unavailable to Afghanistan asset too was under American Influenced Shah Raza shah Pahlwei.This economic blockade of Afghanistan helped to harbour an animosity between Afghanistan and Pakistan on one side and India and Pakistan on the other. This in fact led to PAK-CHINA NEXSIS ON ONE side, Indo-afghan-Russian Nexuses on the other side. The American and west forces shimmed in the troubled waters to gain control on the golf waters, oil and resources including Iran .This so infused cold water relationship among Muslim world led to hindering of Kashmir cause.

The Iraq taking sides with Russia, Iran with USA further complicated the solution of Kashmir. Kashmir solution and independent resolution depends on free Iranian-Afghanistan-PAKISTAN –China-South ASIAN STATES of USSR BORDERS AND TRADE on one side and India-Japan-Nepal-china-BENGLADESH-Malaysia-Indonesia trade on the other side. This needs a friendly mode among Asian neigbhiours.This may be possible with the dawn from east and dusk to west. The whole euphoria of ISLAMOPHOBIA and china or India competing for superpower status.

This status of superiority passed through peaceful Kashmir.Afganistan,Pakistan and of course powerful Iran ,China, India Both the Russian white and the western white tries to disdain this and gives rise to new forms of wars in the world. There is reaction to every action so is true here and they malign it as Islamic terrorism.Forgeting the reality of inventing, nursing and propagating it.

Thus we have to understand Taleban, Kashmiri and other Muslim aspirations, subjugated for years under various London Plans. The Peshawar university weapons. The weaponization of Peshawar and Pakistan free constituencies was the result of the London plan. The proof is the cache at Peshawar University on 2oth feruary, 1973.All these weapons bore forgiven marks of manufacture and design. The movement gave birth to the Baluchistan crisis.

And many tribesmen left for the mountains to sustain a revolt. This revolt gave rise to new talabanization of Pakistani areas with Afgan refugee influx. The rise of ziaulhaq as a counter leader to annuli Zulfikar Ali Bhatoo also started with the uprising of Bolochistan.It is said the Zia masterminded the so called Jihad against Russian on American behest. The American interests in the area came to be executed through this plan and they succeeded in both killing and Islamic Thicker and great leaders and stateman, who gave Pakistan a deerrent, otherwise the London plan would have been success much earlier. This whole behind the scenes tactics of west, India and Russia is responsible for the woes of the world now which is named Islam phobia.

Iran Launches Satellite

The launch of the Safir-2 Rocket, a satellite with research (what research type?) and telecommunication (among who?) is a strong matter of concern for Israel, EU and USA.

The launching technology is very similar to that used for ballistic missiles and then feasible to be switched up to other “peaceful” program.

Iranian Government gives high relevance to entry and installs a wide missiles range with different range capability.

They are also interested in taking lead of the Muslims world, by showing an organized and modernized regional power.

From this perspective, Iranian’s best competitors are Pakistan and Al-Qaeda.
Pakistan already owns its repository of Nuclear weapons.
Al-Qaeda is attempting to access to this technology by associated third parties.
If Pakistan fails in maintain internal order risk of a clash against India is feasible.

Then back again to Iran, we have a quite advance technology Country well determined in pursuing its own targets.

This is likely to be a military transition policy in which Government is trying consolidating its position across Middle East and acts a large role in supporting all anti-Israelis movements.

All this drive to an obvious number of military options and efforts in which combination of Israel and USA or NATO response should be based on realistic assessment.

There is a need to understand all possible worst cases with minimum general impact both in the public opinion and in the foreign relations in the Muslim Word, Russia and China.

The Iranian missile Shabab-3 derives by the North Korean No-Dong 1 re-elaborated. The exchange of technology between these states may be an additional point of concerns and possible military option being considered.

Suspect of connection with Russia and China in development the long range ballistic Shabab-3 version is feasible but not demonstrated.

From a certain perspective the raise of Iran as regional reference power may create high expectations from Muslims communities in Russia and China to the Uyghur population in the Xinijang Region together with an increase of terrorism, separatism and religious extremism.

Beyond these analysis we have then challenge of facing Iranian threat according to the information we have acquired and take a decision of striking.
We just need to decide when and where.

Successful Exploitation of Shale Gas in Europe depends on solving key Challenges

Europe face the same challenges US shale gas exploitation efforts faced when it started up.  As there are similarities, there are also many differences, which makes the hunt for Shale Gas in Europe a different challenge than was and still is in the US.
These challenges European government(s) and oil and gas industry faces have to be adressed and a focus has to be made on these at this stage.
A successful exploration and production of any potential within the Shale Gas plays that could be present depends on solving these challenges.
Shale Gas concept
There are several challenges – and all are connected to the learning curve of Shale Gas potential in especially North America (US and Canada), however not liimited to this continent as f.inst China has begun to ramp up their efforts to exploits Shale Gas potential within their country.
ET08410_Sommer.jpg
It is however important to state – European Shale Gas potential and its exploitation strategy can not follow a blue print of what is done or being done at the present in the US or Canada.
Shale Gas or should I state in general unconventional resources– do not behave that uniformly – and the only certainty we have – its going to be different from the US and Canada, or for that sake rest of the world, as it is with conventional resources and how we exploit them.
P-002746-00-04h.jpg

1.     Policy issues
2.     Environmental concerns
3.     Technology
4.     Geotechnical understanding of Shale Gas properties and its effect on the exploitation potential
5.     Engineering aspects
6.     Service industry
7.     Economy of these projects

I will address  these key issues and what i think Europe should focus on at this moment.

Policy wise
European Union as the policy maker versus Europe consisting of 27 countries and Europe consist of 45 countries including those shared with the Asian continent.
EU was founded in 1993, and therefore a young union, compared to the US f.inst.
There are spoken several different languages within the EU, some have kingdoms (9 of them) and others have republics.
This tells you straight away that Europe is not one unit – every country has its unique setting seen from a political and regulatory setting
It is challenging for EU to have one common energy policy which is uniformly followed all over Europe.

o   Environmental regulations and laws and how they interact with other legislator bodies in a country – are there clearly defined in legislation what role and responsibility environmental unit in a country has and how industry should work with them to ensure development of unconventional plays?
o   Legislative design, the previous step was a sub-topic of this overall topic – as environmental, fiscal, industrial energy laws and f.inst land laws interact, and clear guidelines have to be developed in order for a player to minimize its risk in a unconventional project.
o   Regulatory bodies – one shop stop for players to work towards – as they work on in Poland to mimic North American model
o   Infrastructure – houses, roads, industrial plots etc and also given gas pipeline infrastructure
o   Taxation regulation on capex and opex costs versus income

EU Energy Policy (I make reference to statements made by Michael Schuetz in the EU Indigenous Fossil Fuels committee)

"Magic Triangle" of EU energy policy: »
Economic/affordable
Safe and secure
Sustainable:
environmental concerns
• climate change/CO2
In EU's Second Strategic Energy Review from 2008 it is stated; quote
"[...] high oil prices and the security premium to be placed on indigenous resources increase the interest of extracting indigenous oil and gas reserves, including unconventional reserves, insofar as this can be achieved in a sustainable manner."

Given that some EU Countries have identified and begun exploration of potential Shale Gas resources, like;
Poland
Holland
France
Germany
Switzerland
Sweden
UK
Austria
Italy

Other European countries outside EU have also reasons to believe they have Shale Gas resources, such as;
Ukraine
Turkey

Outside Europe there are countries with potential that can directly affect the unconventional resource market in Europe, and these are;
Russia
China
US and Canada are the market leaders when it comes to both exploration and exploitation of these resources.
There have been made several attempts to assess the volumetric potential for Global Shale Gas on the various continents. Common for these are that there will be some few regions which will dominate the Shale Gas exploitation in the years to come, hence also direct the focus of technology, service providers and operators of course. Below is ConocoPhillps view and estimate of the global resource estimate of unconventional resources. It can be seen that Europe is not seen to rank amongst the top 6 continents.
mcmaster(1).jpg

Given this discussion i think there is a need in Europe for a body that will have its mission to
"To facilitate the factual and collaborative exchange of unconventional gas knowledge and challenges among government, regulators, industry and public stakeholders for the exploration and production of the resource in an environmentally sensitive and economical manner."

Environmental concerns
Here we will have a synergy between legislation variations between European countries and how well developed infrastructure is, hence urban development and preservation of nature and concerns what effect its exploitation will have on needed resources such as ground water f.inst. or use of water in water management when exploiting these resources (availability, amount and management of contaminants)
2010_0903_burning_shale2_m.jpg
Big difference between f.inst Austria's very strict regulations and France need to think nature preservation of vital tourist interest areas, and Poland's more relaxed attitude towards these issues.
The shale gas drilling process requires up to 2.3 million litres of water, plus hydraulic fracturing–or "fracking" –which takes another 17 million litres per well.
Up to 1% of these fluids are chemical to stimulate drilling process or to perform frac in the potential producing units.
That means that 170.000 litres of chemical are used in the frac process and 23.000 litres of chemicals in the drilling process.
So around 200.000 litres of chemicals are used pr well if its going to production.
How these chemicals are acting together with the sub-surface and potential leak into ground water, is still not 100% understood, as our experience is fairly limited and monitoring of these chemical have not been done in real cases yet. Tracers applied to these chemicals would be one way to go, and to drill monitoring wells around a Shale Gas field to see if migration of these chemicals constitutes any environmental danger. Also there will be a need to have proper water/waste water management of used drilling/frac water coming back to the surface. It requires on-site management, but also post-drill management and waste procedures/treatment of this water.
Water is fairly readily available in the U.S, European countries will face bigger difficulties transporting large volumes and sticking with environmental guidelines on disposal.
Therefore there is a need for transparency and trustworthy information to the public is one of the key issues here, and these challenges have to be addressed out in the public so the European public gets to understand what the environmental impact is from these activities and what is done to ensure the public that there is no imminent danger from these activities.
The industry has to explain and calm the public by telling and stating how much effort it will put into the society to ensure that the environmental concern is no issue.
It is not enough just to state there is no concern – it has to prove this by showing the public what is done and what will be done to ensure environment will not be hampered by its activity.
The industry together with the government will have to lay out the various programs it initiates, its reconstruction programs, how it manage its water during exploration and production.

Technology
Here I will go straight to the point – the bottleneck in Europe at the moment is Research and Development within the area of unconventional resource exploitation.
It is essentially non-existent at the moment, as majority of research is based on other continents when it comes to unconventional resource exploration and exploitation. Yes, we have European companies involved in Shale Gas potential in other continents and we can leverage on their experience, however, little or nothing is done on European cases – as they are barely existent at the moment – hence we do not have any experience on how to do this in Europe given our constraints and opportunities.
This is already seen a need to focus more on this in North American exploration an exploitation of unconventional resources – in order to pull some leverage on a collective effort to enhance the recovery factor of these rervoirs – which at the moment is very low.
At the moment is more like empirical science applied in North America, and as we learn we apply – trial and error. Some places this works very well, others it don't.
Fracturing-Improving-technology-HEX3.jpg
Producers in the Marcellus shale in the US may be forced to curtail natural gas production unless they can come up with a viable way to dispose of ethane, an associated gas. There is a need to propose a framework for assessing the viability of options on how to handle this issue. This could be a concern in Europe as well, and technological research should be promoted in this area.
In most natural gas producing regions, ethane is a highly valued byproduct of natural gas production, sold as an important feedstock for the petrochemical industry. But in the rapidly growing Marcellus producing region of the Appalachian basin, some natural gas producers view ethane as a contaminant that could threaten development plans in the area.

There is therefore a need for a Collaborative effort of exchange of knowledge from existing exploration and production at other continents has to be stronger and established in Europe.
Government level collaboration has to be established to facilitate the dialogue on how to address energy supply, cost and demand issues, and together with the industry look at options in a transparent and regulated manner.
Technology solutions will from experience come to a high degree from smaller start-up companies with background from academic institutions.
EU needs to look into options on how to stimulate technologists to bring ideas from the academic world into the commercial world as fast as possible and as effective as possible.

Geotechnical understanding
As the North American Shale Gas potential has been revealed and being exploited as we speak, and done so for a decade or so now, it still remains to understand vital factors from a geological standpoint of view. This based on the fact that we have understood that Shale Gas in not just Shale Gas – there is nothing such as a uniform Shale property, which we can extrapolate to any projects around the world.
Geological properties of these shale combined with various geological settings and development histories, makes Shale Gas exploration and Production a highly complicated matter.
Only within f.inst. the Marcellus shale in the US, the operators experience a tremendous variation in producability of the Shale, as its geological properties changes – mainly its geotechnical properties
To understand these Shales – there is a need for a large amount of raw data for the geoscientists and physicists to evaluate in order to be able to predict and elude the better production areas from the worse ones.
Data such as seismic data, well data are vital, and its important to collect the most optimal and mostly the highest end technology has to be applied when collecting the data, but not only that – when analyzing the data in order to be able to give the best advises to how to exploit these unconventional resources.
Linked to this, there will have to be put a larger efforts into mapping out ground water resources, and not limited to the traditional levels we have exploited so far, but to actually do a proper water exploration at the same efforts as we do the unconventional and conventional exploration.
All this will put a stress on several other challenges, which I will come back to.
European geology is more complex than the North American Geology and will require a smarter approach to identify and exploit commercial shale gas resources
A serious problem that can emerge for producers of high-BTU (British Thermal Unit), or "rich" gas in Europe is that before this gas can be delivered to pipelines for transportation to market, natural gas liquids (NGLs) must be extracted from the gas. Therefore the understanding of hydrocarbon constitution is of importance as some regions might have a large content of Ethane, and hence the need for extraction capacity at or near their production site.
Therefore there will be a need to look at this geological driven aspect in an engineering and infrastructure perspective, as gas-processing infrastructure to extract all the NGLs from gas in the high-BTU gas regions has to be projected and assessed for.
Feasibility studies have to be performed for this scenario, and see if Europe is ready for this type of infrastructure and industry development.
Then – is there a market for Ethane in Europe – and in case it is – where is it – and does it coincide with where you will find it – or is there a need for further infrastructure to facilitate it (petrochemical industry)?

Therefore European government and industry should focus on development of applied Science Unconventional Resource planning and production is needed within EU and rest of Europe.
This has to be linked with a body or organization consisting of industry and government including education that will address the present and future need for workforce within this area.

Engineering aspects
As we have seen in North America, we went from the traditional vertical wells with simple fracturing technology in its infancy of exploiting the unconventional potential.
1981 the 1st well was drilled on these resources in the Barnett Shale, and an average of 7 wells pr year was drilled up to 1992 when the 1st horizontal well was drilled on these resources. The average amount of wells now became around 40 pr year, as in 1997 the 1st slickwater frac procedure was used, and we jumped to an averge of 73 well pr year. The amount of vertical wells dropped on behalf of the horizontal ones, and in 2007 we had around 2500 wells drilled.
Fayettville was developed much later and its first well was drilled in 2004 and its first horizontal well was drilled in 2005 and in the same year slickwater frac was used.
The speed of implementing new technology is tremendously different, driven by experience from Barnett shale play. At the moment Fayetteville drills around 1000 wells.
Now, experience tells us that the solution is not only to drill horizontal wells, but to limits its reach, and to perform multi-stage fracs on them.
However, technology has to adapt to geological variation and to changes due to production performed on it.
Decline rate on Shale Gas is a totally different chapter than seen in conventional resources, and how to cope with this together with how to prolong peak production and to create a higher production plateau is important engineering tasks ahead of us.

Both European industry and European government have much to lose and need to collaborate on R&D programs to enable these new technologies to be developed
Development of these resources will require new technologies if exploration and production is to be undertaken in a cost effective and environmentally responsible manner
The driving force of R&D initiatives should be focused on lower F&D costs to ensure that produced natural gas will be competitive in the European market

Service Industry
A lack of land-based rigs and access to hydraulic rock-fracturing technology will put restraints on potential for profitable shale gas production in Europe
Land rig capacity will need to rapidly increase," to make these projects commercially viable
While there are an estimated 1,500 land rigs available in the U.S, only 74 suitable rigs are accessible in Europe
Since European Union limits on imports on rigs and rig equipment, this issue will have to addressed locally, and ensure rig capacity and service capacity is built in Europe itself.
How do we go about this issue, without creating a large overhead cost on the exploration and production companies?

There is a need to facilitate rig construction factory units around Europe, combined with on the demand driven frac unit constructions combined with training of local experts to perform both tasks, drilling and frac'ing.
This will drive down the prices and costs of these elements in the medium to long run, but has to be balanced with the need to create a healthy business model for those set up for these activities.
In the EU, there is a need for collaboration between service industry and government to ensure a framework that will work for both parties and serve the operators at an optimal level.
In addition there is a need for the academic environment to build up applied science units to address Research and Development and to educate specialists within these areas.


Economy of these projects
Rapid increase in the development costs for unconventional gas drilling is a major concern for the industry at the moment. Average costs for a typical well are between $7.5 million and $10 million, with additional operating costs of around $2.25 per thousand cubic feet of gas extracted, or mcf, this implies that for projects to remain profitable, gas prices would need to stay above $7.50 per mcf.  At the moment the gas is trading around $4-5 per mcf.
Another aspect of economy is how long time I takes to bring a project from idea to a commercial unit.
Let us take Poland as an example;
Poland is still a mainly agricultural nation comprised of thousands of family smallholdings of an average 14 hectares.
Planning a well head on land in Poland will require companies to negotiate with each family, which will inevitably delay processing. Time is money, and also it is difficulty to unitize a production unit, if many parties are involved in it, which complicate a project and puts an economic risk to it.
There will be a European need for Gas at least as far as into 2050 as we can see it, and mostl likely beoynd this time as well.
Prognosis states that Europe will have around 80% of its energy need covered by import if the existing energy provisions are kept. Will Shale Gas be able to make this dependency less, or is the potential too small, and the cost to get it - too high?
The politicians together with the industry needs to put their heads together and make some connections between the vision and missions of the EU energy policy document and the efforts needed to achieve them.

Powder metallurgy - Mud Clarifier ZX - Hydraulic Drilling Rig TR300

History and capabilities The history of powder metallurgy and the art of metals and ceramics sintering are intimately related. Sintering involves the production of a hard solid metal or ceramic piece from a starting powder. There is evidence that iron powders were fused into hard objects as early as 1200 B.C. In these early manufacturing operations, iron was extracted by hand from metal sponge following reduction and was then reintroduced as a powder for final melting or sintering. A much wider range of products can be obtained from powder processes than from direct alloying of fused materials. In melting operations the "phase rule" applies to all pure and combined elements and strictly dictates the distribution of liquid and solid phases which can exist for specific compositions. In addition, whole body melting of starting materials is required for alloying, thus imposing unwelcome chemical, thermal, and containment constraints on manufacturing. Unfortunately, the handling of aluminium/iron powders poses major problems. Other substances that are especially reactive with atmospheric oxygen, such as tin, are sinterable in special atmospheres or with temporary coatings. In powder metallurgy or ceramics it is possible to fabricate components which otherwise would decompose or disintegrate. All considerations of solid-liquid phase changes can be ignored, so powder processes are more flexible than casting, extrusion, or forging techniques. Controllable characteristics of products prepared using various powder technologies include mechanical, magnetic, and other unconventional properties of such materials as porous solids, aggregates, and intermetallic compounds. Competitive characteristics of manufacturing processing (e.g., tool wear, complexity, or vendor options) also may be closely regulated. Powder Metallurgy products are today used in a wide range of industries, from automotive and aerospace applications to power tools and household appliances. Each year the international PM awards highlight the developing capabilities of the technology. Isostatic powder compacting Isostatic powder compacting is a mass-conserving shaping process. Fine metal particles are placed into a flexible mold and then high gas or fluid pressure is applied to the mold. The resulting article is then sintered in a furnace. This increases the strength of the part by bonding the metal particles. This manufacturing process produces very little scrap metal and can be used to make many different shapes. The tolerances that this process can achieve are very precise, ranging from +/- 0.008 inches for axial dimensions and +/- 0.020 inches for radial dimensions. This is the most efficient type of powder compacting.(The following subcategories are also from this reference.) This operation is generally applicable on small production quantities, as it is more costly to run due to its slow operating speed and the need for expendable tooling. Process Characteristics Compacts powdered metal within a flexible mold by uniformly applied, high fluid/gas pressure Parts are sintered to increase strength through metallurgical bonding Produces very little scrap material Can use alloy combinations and filler Can produce complex workpiece geometries Equipment There are many types of equipment used in Powder Compacting. There is the mold, which is flexible, a pressure mold that the mold is in, and the machine delivering the pressure. There are also controlling devices to control the amount of pressure and how long the pressure is held for. The machines need to apply anywhere from 15,000 psi to 40,000 psi for metals. Geometrical Possibilities Many desired shapes can be formed from a variety of engineering materials. Typical work-piece sizes range from 1/4in. to 3/4in. thick and 1/2in. to 10in. in length. However, it is possible to compact workpieces that are between 1/16in. and 5 in. thick and 1/16in. and 40in. in length. Tool style Isostatic tools are available in three styles, free mold (wet-bag), coarse mold(damp-bag), and fixed mold (dry-bag). The free mold style is the traditional style of isostatic compaction and is not generally used for high production work. In free mold tooling the mold is removed and filled outside the canister. Damp bag is where the mold is located in the canister, yet filled outside. In fixed mold tooling, the mold is contained with in the canister, which facilitates automation of the process. Hot Isostatic Pressing (HIP) In this operation, the part is compressed and sintered simultaneously by applying heat ranging from 900F (480C) to 2250F (1230C). Argon gas is the most common gas used in HIP because it is an inert gas, thus preventing chemical reactions during the operation. Cold (or room-temperature) Isostatic Pressing (CIP) This typically uses fluid as a means of applying pressure to the mold. After removal the part still needs to be sintered. Design Considerations Isostatic powder compaction can have thinner walls and larger products. No lubricants are need for Isostatic powder compaction. For example: minimum wall thickness is 0.05 inches and the product can have a weight between 40 and 300 pounds. There is 25 to 45% shrinkage of the powder after compacting. Typical Workpiece Materials Some of the more used metals used for the powder are iron, alloyed steels, brass, stainless steel, and bronze. You would pick between these depending on what you want such as steel for strength and application. Powder production techniques Any fusible material can be atomized. Several techniques have been developed which permit large production rates of powdered particles, often with considerable control over the size ranges of the final grain population. Powders may be prepared by comminution, grinding, chemical reactions, or electrolytic deposition. Several of the melting and mechanical procedures are clearly adaptable to operations in space or on the Moon. Powders of the elements Ti, V, Th, Nb, Ta, Ca, and U have been produced by high-temperature reduction of the corresponding nitrides and carbides. Fe, Ni, U, and Be submicrometre powders are obtained by reducing metallic oxalates and formates. Exceedingly fine particles also have been prepared by directing a stream of molten metal through a high-temperature plasma jet or flame, simultaneously atomizing and comminuting the material. On Earth various chemical- and flame-associated powdering processes are adopted in part to prevent serious degradation of particle surfaces by atmospheric oxygen. Atomization Atomization is accomplished by forcing a molten metal stream through an orifice at moderate pressures. A gas is introduced into the metal stream just before it leaves the nozzle, serving to create turbulence as the entrained gas expands (due to heating) and exits into a large collection volume exterior to the orifice. The collection volume is filled with gas to promote further turbulence of the molten metal jet. On Earth, air and powder streams are segregated using gravity or cyclonic separation. Most atomized powders are annealed, which helps reduce the oxide and carbon content. The water atomized particles are smaller, cleaner, and nonporous and have a greater breadth of size, which allows better compacting. Simple atomization techniques are available in which liquid metal is forced through an orifice at a sufficiently high velocity to ensure turbulent flow. The usual performance index used is the Reynolds number R = fvd/n, where f = fluid density, v = velocity of the exit stream, d = diameter of the opening, and n = absolute viscosity. At low R the liquid jet oscillates, but at higher velocities the stream becomes turbulent and breaks into droplets. Pumping energy is applied to droplet formation with very low efficiency (on the order of 1%) and control over the size distribution of the metal particles produced is rather poor. Other techniques such as nozzle vibration, nozzle asymmetry, multiple impinging streams, or molten-metal injection into ambient gas are all available to increase atomization efficiency, produce finer grains, and to narrow the particle size distribution. Unfortunately, it is difficult to eject metals through orifices smaller than a few millimeters in diameter, which in practice limits the minimum size of powder grains to approximately 10 m. Atomization also produces a wide spectrum of particle sizes, necessitating downstream classification by screening and remelting a significant fraction of the grain boundary. Centrifugal disintegration Centrifugal disintegration of molten particles offers one way around these problems. Extensive experience is available with iron, steel, and aluminium. Metal to be powdered is formed into a rod which is introduced into a chamber through a rapidly rotating spindle. Opposite the spindle tip is an electrode from which an arc is established which heats the metal rod. As the tip material fuses, the rapid rod rotation throws off tiny melt droplets which solidify before hitting the chamber walls. A circulating gas sweeps particles from the chamber. Similar techniques could be employed in space or on the Moon. The chamber wall could be rotated to force new powders into remote collection vessels (DeCarmo, 1979), and the electrode could be replaced by a solar mirror focused at the end of the rod. An alternative approach capable of producing a very narrow distribution of grain sizes but with low throughput consists of a rapidly spinning bowl heated to well above the melting point of the material to be powdered. Liquid metal, introduced onto the surface of the basin near the center at flow rates adjusted to permit a thin metal film to skim evenly up the walls and over the edge, breaks into droplets, each approximately the thickness of the film. Other techniques Another powder-production technique involves a thin jet of liquid metal intersected by high-speed streams of atomized water which break the jet into drops and cool the powder before it reaches the bottom of the bin. In subsequent operations the powder is dried. This is called water atomisation. The advantage is that metal solidifies faster than by gas atomization since thermal conductivity of water is some magnitudes higher. The solidification rate is inversely proportional to the particle size. As a consequence, one can obtain smaller particles by water atomisation. The smaller the particles, the more homogeneous the micro structure will be. Notice that particles will have a more irregular shape and the particle size distribution will be wider. In addition, some surface contamination can occur by oxidation skin formation. Powder can be reduced by some kind of pre-consolidation treatment as annealing. Finally, mills are now available which can impart enormous rotational torques on powders, on the order of 2.0107 rpm. Such forces cause grains to disintegrate into yet finer particles. Powder compaction Powder compaction, also known as powder pressing, is the process of compacting metal powder in a die through the application of high pressures. The dies are of the shape of the desired final shape of the workpiece. The workpiece is then removed and sintered. The density of the compacted powder is directly proportional to the amount of pressure applied. Typical pressures range from 80 psi to 1000 psi, pressures from 1000 psi to 1,000,000 psi have been obtained. Pressure of 10 tons/in to 50 tons/in are commonly used for metal powder compaction. To attain the same compression ratio across a component with more than one level or height, it is necessary to work with multiple lower punches. A cylindrical workpiece is made by single-level tooling. A more complex shape can be made by the common multiple-level tooling. Production rates of 15 to 30 parts per minutes are common. There are four major classes of tool styles: single-action compaction, used for thin, flat components; opposed double-action with two punch motions, which accommodates thicker components; double-action with floating die; and double action withdrawal die. Double action classes give much better density distribution than single action. Tooling must be designed so that it will withstand the extreme pressure without deforming or bending. Tools must be made from materials that are polished and wear-resistant. Better workpiece materials can be obtained by repressing and re-sintering. Here is a table of some of the obtainable properties. Typical workpiece materials Workpiece material Density (grams/cc) Yield strength (psi) Tensile strength (psi) Hardness (HB) Iron 5.2 to 7.0 5.1*103 to 2.3*104 7.3*103 to 2.9*104 40 to 70 Low alloy steel 6.3 to 7.4 1.5*104 to 2.9*104 2.00*104 to 4.4*104 60 to 100 Alloyed steel 6.8 to 7.4 2.6*104 to 8.4*104 2.9*104 to 9.4*104 60 and up Stainless steel 6.3 to 7.6 3.6*104 to 7.3*104 4.4*104 to 8.7*104 60 and up Bronze 5.5 to 7.5 1.1*104 to 2.9*104 1.5*104 to 4.4*104 50 to 70 Brass 7.0 to 7.9 1.1*104 to 2.9*104 1.6*104 to 3.5*104 60 Design considerations Must be able to remove part from die. Maximum surface area below 20 square inches. Minimum wall thickness of 0.08 in. Sharp corners should be avoided. Should avoid height to diameter ratios greater than 7:1. Adjacent wall thickness ratios greater than 2.5 to 1 should be avoided. One of the major advantages of this process is its ability to produce complex geometries. Parts with undercuts and threads require a secondary machining operation. Typical part sizes range from 0.1 in to 20 in. in area and from 0.1 in. to 4 in. in length. However, it is possible to produce parts that are less than 0.1 in. and larger than 25 in. in area and from a fraction of an inch to approximately 8 in. in length. Powder pressing In the typical powder pressing process a powder compaction press is employed with tools and dies. Normally, a die cavity that is closed on one end (vertical die, bottom end closed by a punch tool) is filled with powder. The powder is then compacted into a shape and then ejected from the die cavity. Various components can be formed with the powder compaction process. Some examples of these parts are bearings, bushings, gears, pistons, levers, and brackets. When pressing these shapes, very good dimensional and weight control are maintained. In a number of these applications the parts may require very little additional work for their intended use; making for very cost efficient manufacturing. In some pressing operations (such as hot isostatic pressing) compact formation and sintering occur simultaneously. This procedure, together with explosion-driven compressive techniques, is used extensively in the production of high-temperature and high-strength parts such as turbine blades for jet engines. In most applications of powder metallurgy the compact is hot-pressed, heated to a temperature above which the materials cannot remain work-hardened. Hot pressing lowers the pressures required to reduce porosity and speeds welding and grain deformation processes. Also it permits better dimensional control of the product, lessened sensitivity to physical characteristics of starting materials, and allows powder to be driven to higher densities than with cold pressing, resulting in higher strength. Negative aspects of hot pressing include shorter die life, slower throughput because of powder heating, and the frequent necessity for protective atmospheres during forming and cooling stages. Sintering The following text needs to be harmonized with text in Sintering. Main article: Sintering Solid state sintering is the process of taking metal in the form of a powder and placing it into a mold or die. Once compacted into the mold the material is placed under a high heat for a long period of time. Under heat, bonding takes place between the porous aggregate particles and once cooled the powder has bonded to form a solid piece. Sintering can be considered to proceed in three stages. During the first, neck growth proceeds rapidly but powder particles remain discrete. During the second, most densification occurs, the structure recrystallizes and particles diffuse into each other. During the third, isolated pores tend to become spheroidal and densification continues at a much lower rate. The words Solid State in Solid State Sintering simply refer to the state the material is in when it bonds, solid meaning the material was not turned molten to bond together as alloys are formed. One recently developed technique for high-speed sintering involves passing high electrical current through a powder to preferentially heat the asperities. Most of the energy serves to melt that portion of the compact where migration is desirable for densification; comparatively little energy is absorbed by the bulk materials and forming machinery. Naturally, this technique is not applicable to electrically insulating powders. To allow efficient stacking of product in the furnace during sintering and prevent parts sticking together, many manufacturers separate ware using Ceramic Powder Separator Sheets. These sheets are available in various materials such as alumina, zirconia and magnesia. They are also available in fine medium and coarse particle sizes. By matching the material and particle size to the ware being sintered, surface damage and contamination can be reduced while maximizing furnace loading. Continuous powder processing The phrase "continuous process" should be used only to describe modes of manufacturing which could be extended indefinitely in time. Normally, however, the term refers to processes whose products are much longer in one physical dimension than in the other two. Compression, rolling, and extrusion are the most common examples. In a simple compression process, powder flows from a bin onto a two-walled channel and is repeatedly compressed vertically by a horizontally stationary punch. After stripping the compress from the conveyor the compact is introduced into a sintering furnace. An even easier approach is to spray powder onto a moving belt and sinter it without compression. Good methods for stripping cold-pressed materials from moving belts are hard to find. One alternative that avoids the belt-stripping difficulty altogether is the manufacture of metal sheets using opposed hydraulic rams, although weakness lines across the sheet may arise during successive press operations. Powders can also be rolled to produce sheets. The powdered metal is fed into a two-high rolling mill and is compacted into strip at up to 100 feet per minute. The strip is then sintered and subjected to another rolling and sintering. Rolling is commonly used to produce sheet metal for electrical and electronic components as well as coins. Considerable work also has been done on rolling multiple layers of different materials simultaneously into sheets. Extrusion processes are of two general types. In one type, the powder is mixed with a binder or plasticizer at room temperature; in the other, the powder is extruded at elevated temperatures without fortification. Extrusions with binders are used extensively in the preparation of tungsten-carbide composites. Tubes, complex sections, and spiral drill shapes are manufactured in extended lengths and diameters varying from 0.5-300 mm. Hard metal wires of 0.1 mm diameter have been drawn from powder stock. At the opposite extreme, large extrusions on a tonnage basis may be feasible. There appears to be no limitation to the variety of metals and alloys that can be extruded, provided the temperatures and pressures involved are within the capabilities of die materials. Extrusion lengths may range from 3-30 m and diameters from 0.21 m. Modern presses are largely automatic and operate at high speeds (on the order of m/s). Extrusion Temperatures Of Common Metals And Alloys Metals and alloys Temperature of extrusion, K C Aluminium and alloys 673-773 400-500 Magnesium and alloys 573-673 300-400 Copper 1073-1153 800-880 Brasses 923-1123 650-850 Nickel brasses 1023-1173 750-900 Cupro-nickel 1173-1273 900-1000 Nickel 1383-1433 1110-1160 Monel 1373-1403 1100-1130 Inconel 1443-1473 1170-1200 Steels 1323-1523 1050-1250 Special products Many special products are possible with powder metallurgy technology. A nonexhaustive list includes Al2O3 whiskers coated with very thin oxide layers for improved refractories; iron compacts with Al2O3 coatings for improved high-temperature creep strength; light bulb filaments made with powder technology; linings for friction brakes; metal glasses for high-strength films and ribbons; heat shields for spacecraft reentry into Earth's atmosphere; electrical contacts for handling large current flows; magnets; microwave ferrites; filters for gases; and bearings which can be infiltrated with lubricants. Extremely thin films and tiny spheres exhibit high strength. One application of this observation is to coat brittle materials in whisker form with a submicrometre film of much softer metal (e.g., cobalt-coated tungsten). The surface strain of the thin layer places the harder metal under compression, so that when the entire composite is sintered the rupture strength increases markedly. With this method, strengths on the order of 2.8 GPa versus 550 MPa have been observed for, respectively, coated (25% Co) and uncoated tungsten carbides. It is interesting to consider whether similarly strong materials could be manufactured from aluminium films stretched thin over glass fibers (materials relatively abundant in space).

Hunter Valley Coal Chain

The chain


Coal loader at Port Waratah, Newcastle
Coal generally goes through the following stages between mine and port:


The producer makes arrangements to sell coal to a buyer on certain terms.


The coal is mined (most of the coal mines in the Hunter Valley are open cut mines, also known as open pit mines) and stored either at a railway siding located at the mine or at a coal loading facility (used by several mines).


The coal is then transported to the Port of Newcastle, almost exclusively done by rail. Some coal is transported to the port by truck, but this generally requires permission from the local government (due to the effect on roadways and other infrastructure) and is also usually more costly per tonne than rail transport.


The coal is offloaded at the port onto stockpiles in the Port Waratah Coal Services facilities.


Once the vessel arrives at the port, the coal is loaded onto the vessel.


The vessel then transports the coal to its destination determined by the buyer.


HVCC Logistics Team


In 2003, the Hunter Valley Coal Chain Logistics Team (HVCCLT) was established to improve the movement of coal from Hunter Valley mines to the ports coal loaders and then to markets across the globe. HVCCLT pools the resources of port operators Newcastle Port Corporation and Port Waratah Coal Services, railway operators Pacific National and QRNational, and railway infrastructure managers Australian Rail Track Corporation and Railcorp into one logistics team.


Producers


The major coal producers in the Hunter Valley, which utilise approximately 70 per cent of the HVCC capacity, are:


Coal & Allied Industries Limited, a company listed on the ASX and managed by Rio Tinto (part of Rio Tinto Coal Australia). Coal & Allied owns three main mining operations in the Hunter Valley, being Hunter Valley Operations, Mount Thorley Operations/Warkworth Mine and Bengalla Mine.


Xstrata Coal NSW Pty Ltd, a subsidiary of Xstrata plc. Xstrata owns (either through joint ventures or companies) and manages and operates 10 mining operations in the Hunter Valley. Xstrata Coal NSW is the states largest coal producer.


Anglo Coal Australia Pty Ltd, a subsidiary of Anglo American plc. Anglo has a majority interest in Dartbrook and Drayton mines.


Hunter Valley Energy Coal Limited (a wholly owned subsidiary of BHP Billiton).


The remaining 30 per cent of coal exported is produced by the small coal producers including:


AMCI Holdings Australia Pty Limited;


Bloomfield Collieries Pty Limited;


Camberwell Coal Pty Limited;


Centennial Coal Company Limited;


Donaldson Coal Pty Limited;


Excel Mining Ltd;


Gloucester Coal Ltd;


Lake Coal (Road Coal Only);


Muswellbrook Coal Co Ltd;


Southland Coal Pty Ltd; and


White Mining Limited.


Consumers


Most coal produced in the Hunter Valley is sold directly by coal mines (producers) to overseas buyers. About 20 per cent of coal is sold by traders who do not mine coal but act as agents or intermediaries in coal sales. The coal traders operating in the Hunter Valley include:


Noble Asia Pacific Ltd;


Peabody Coaltrade Pty Ltd;


AEP Energy Services Limited; and


Glencore International AG.


The majority of Australian coal was traditionally sold to Japanese steel mills or power utilities in accordance with long term contracts. Those contracts were the subject of annual price and volume negotiations. The Japanese steel mills, operating in a coordinated manner and collectively known as the SM, negotiated prices for coking coal. One of the steel mills would be appointed as the lead negotiator for the initial contracts with producers. Prices in subsequent contracts would be based on these enchmark prices, adjusted for coal quality. This led to SM terms being the benchmark for the industry. While coal is still sold under JSM terms, a greater variety of other contract terms now exist.


Rail infrastructure


The railway corridor used is part of the Main North railway line. The Australian Government manages the Hunter rail infrastructure through the Australian Rail Track Corporation (ARTC), formerly owned by the NSW Government through the Rail Infrastructure Corporation (RIC) (now RailCorp). The track is open access and may be used by any accredited rail operator. The other infrastructure associated with coal transport, such as load points, is privately owned, usually by a mine or a coal loader.


There are currently two major above-track (rolling stock) operators using the Hunter Valley rail track. Pacific National is a private operator which transports freight, coal, industrial and agricultural products, including most coal transported by rail. Some coal is now transported by QRNational (Queensland Rail). In addition, CityRail (part of RailCorp) operates passenger services on parts of the track as the Hunter line.


In addition number of coal miners have begun moves to operate their own trains. In September 2009 Xstrata Coal signed a deal with Freightliner Australia (a subsidiary of Freightliner Group Limited) for the provision of rail freight services, commencing in late 2010 and allowing Xstrata to avoid the incumbent operators. The locomotives and rollingstock will be purchased outright by Xstrata from manufacturer UGL Rail.


Port Waratah Coal Services


Port Waratah Coal Services Limited (PWCS) operates the coal export facilities in Newcastle. The coal export facilities consist of two coal loading terminals, located on either side of the South Channel of the Hunter River. These are known as the Kooragang Coal Terminal, on Kooragang Island and the Carrington Coal Terminal in the suburb of Carrington. Each of those terminals comprises equipment for the delivery and storage of coal to the terminal and for the loading of coal onto vessels. PWCS leases the land on which the port is situated from the Government of New South Wales under an agreement which states that the port is maintained as a 'common user facility'.


The coal export facilities operated by PWCS have a total capacity of 113 million tonnes per annum (Mtpa):


Carrington coal terminal has a shiploading capacity of 25 Mtpa. It has berth space for two vessels and shiploading facilities that operate at 2,500 tonnes per hour (tph). Carrington Coal Terminal is able to accept coal deliveries by either road or rail.


Kooragang coal terminal has a shiploading capacity of 88 Mtpa. It has berth space for three vessels and shiploading facilities which can operate at 10,500 tph. Kooragang Coal Terminal is able to accept coal deliveries by rail only.


Kooragang coal terminal has been undergoing expansion due demand since inception. Current works expect to see capacity of the combined loaders (Carrington and Kooragang) at over 102 Mtpa in 2009.


The distribution of loading between Carrington and Kooragang Coal terminals is dependent on a number of factors:


'Capesize' class vessels usually berth at Kooragang Coal Terminal due to their larger size. However, they are also able to load at the Carrington Coal Terminal. 'Handysize' class vessels are loaded at Carrington Coal Terminal also due to their size. 'Panamax' class vessels may be loaded at either Kooragang Coal Terminal or Carrington Coal Terminal.


Coal which is to be delivered by road may only be delivered to Carrington Coal Terminal, and therefore any vessels which are to be loaded with road coal must be loaded at Carrington Coal Terminal.


If the vessel to be loaded is 'geared', that is, it has equipment on deck, then the vessel will usually be scheduled to berth at Carrington Coal Terminal, as the shiploaders at Carrington Coal Terminal are smaller and are therefore more easily able to move in and about equipment on the deck of a vessel.


Remaining vessels are then scheduled to ensure an even queue of vessels is maintained between the Kooragang Coal Terminal and Carrington Coal Terminal. If the queue for one of the terminals is substantially longer than for the other terminal, the schedule may be amended to ensure that the queues are kept reasonably even.


Capacity distribution systems


While productivity in supply chains is an issue for industries of all sizes, few industries have to deal with a network as broad and a demand as pressing as the coal industry.


As Australia's biggest export commodity accounting for 10 percent of export volume, coal is of vital importance to the economy. But while Australia has an abundance of coal and a ravenous world market, particularly in Asia (especially China, with its expanding need for coal in the steel industry), willing to devour it is disadvantaged by the distance that must be overcome to get the product to the market and the huge number of players involved.


It is for this reason that the supply chain must run as smoothly as possible, moving the raw product from the mines, to the port and onto the ships no easy task. In 2005, Australia exported nearly 234 million tonnes of coal and moved 97 percent of this by rail.


But over the last five years, getting the coal to these ports, onto the ships and to the market proved to be a difficult operation as the Chinese and other Asian markets demand soared. Freight bottlenecks rapidly developed, primarily at the Dalrymple Bay Coal Terminal (DBCT) and at Newcastle's Port Waratah.


To cope with these bottlenecks, the terminal operators developed capacity management systems to cope with the volumes.


The two hubs developed independent yet similar systems to cope with the problem of how to reduce queues, with Port Waratah using a "Capacity Balancing System" and DBCT a "Queue Management System".


The Port Waratah model allocates production from the mines to available shipping in a way that maximises the capacity of the terminal.


Since August 2003, there has been evidence that the Hunter Valley coal export infrastructure has been strained and that some coal export growth might have been lost as a result of constraints in the system. In response to this situation, Port Waratah Coal Services (manager of the Kooragang coal terminal (located on Kooragang Island and Carrington coal terminals at the Newcastle Port) applied to the Australian Competition and Consumer Commission (ACCC) to implement a short term capacity distribution system (STCDS) to allocate the current capacity of the coal supply chain to existing coal exporters. This scheme was implemented in June 2004 and interim authorisation to continue a modified version of the scheme until December 2007 called the medium term capacity distribution system (MTCDS) has been granted by the ACCC.
