History of petrolem

Natural history
Ninety-five percent[citation needed] of oil and gas formations derive from the decayed plants and bacteria which sank to the bottom of seas, sheltered lakes and other moist areas. Over time the decayed residue was covered by layers of mud and silt, sinking further down into the Earth’s crust and preserved there between hot and pressured layers, gradually transforming into oil reservoirs.

Human history
Historical references trace oil use in ancient Egypt, Mesopotamia, and Persia through various reports and sacred documents. Oil in general has been used since early human history to keep fires ablaze, and also for warfare. Its importance in the world economy evolved slowly. Wood and coal were used for heating and cooking, while whale oil was used for lighting. Whale oil however, burned to produce a black, smelly, thick residue known as tar or rock oil[citation needed].

The petroleum industry was established in the 8th century, when the streets of Baghdad were paved with tar, derived from petroleum through destructive distillation. In the 9th century, oil fields were exploited in the area around modern Baku, Azerbaijan, to produce naphtha. These fields were described by al-Masudi in the 10th century, and by Marco Polo in the 13th century, who described the output of those oil wells as hundreds of shiploads.[2] Petroleum was distilled by al-Razi in the 9th century, producing chemicals such as kerosene in the alembic, which he used to invent kerosene lamps for use in the oil lamp industry.[3]

The Industrial Revolution generated an increasing need for energy which was fuelled mainly by coal. However, it was discovered that kerosene could be extracted from crude oil and used as a light and heating fuel. Petroleum was in great demand and by the twentieth century had become the most valuable commodity traded on the world market.[4]

Politics of Alternative fuels

Vinod Khosla (a well known invester in IT firms and alternative energy) argues[19] that the political interests of environmental advocates, agricultural businesses, energy security advocates (such as ex-CIA director James Woolsey) and automakers, are all aligned for the increased production of ethanol. He pointed out that from 2003 to 2006, ethanol fuel in Brazil has replaced 40% of its gasoline consumption while flex fuel vehicles went from 3% of car sales to 70%. Brazilian ethanol, which is produced using sugarcane, reduces green house gases by 60-80% (20% for corn produced ethanol). Khosla also says that ethanol is about 10% cheaper per given distance. There are currently ethanol subsidies in the United States but they are all blender’s credits, meaning the oil refineries receive the subsidies rather than the farmers. There are indirect subsidies due to subsidising farmers to produce corn. Vinod says after one of his presentations in Davos, a Senior Saudi oil official came up to him and threatened: “If biofuels start to take off we will drop the price of oil.”[20] Since then, Vinod has come up with a new recommendation that oil should be taxed if it drops below $40.00/barrel in order to counter price manipulation.

Ex-CIA director James Woolsey and U.S. Senator Richard Lugar are also vocal proponents of ethanol.[21]

In 2005, Sweden announced plans to end its dependence on fossil fuels by the year 2020.[22]

Petroleum Holding politics en Venezuela

According to the Oil and Gas Journal (OGJ), Venezuela has 77.2 billion barrels of proven conventional oil reserves, the largest of any country in the Western Hemisphere. In addition it has non-conventional oil deposits similar in size to Canada’s – at 1,200 billion barrels approximately equal to the world’s reserves of conventional oil. About 267 billion barrels of this may be producible at current prices using current technology.[14] Venezuela’s Orinoco tar sands are less viscous than Canada’s Athabasca oil sands – meaning they can be produced by more conventional means, but are buried deeper – meaning they cannot be extracted by surface mining. In an attempt to have these extra heavy oil reserves recognized by the international community, Venezuela has moved to add them to its conventional reserves to give nearly 350 billion barrels of total oil reserves. This would give it the largest oil reserves in the world, even ahead of Saudi Arabia.

Venezuela nationalized its oil industry in 1975-1976, creating Petróleos de Venezuela S.A. (PdVSA), the country’s state-run oil and natural gas company. Along with being Venezuela’s largest employer, PdVSA accounts for about one-third of the country’s GDP, 50 percent of the government’s revenue and 80 percent of Venezuela’s exports earnings. In recent years, under the influence of President Chavez, the Venezuelan government has reduced PdVSA’s previous autonomy and amended the rules regulating the country’s hydrocarbons sector.[15]

In the 1990s, Venezuela opened its upstream oil sector to private investment. This collection of policies, called apertura, facilitated the creation of 32 operating service agreements (OSA) with 22 separate foreign oil companies, including international oil majors like Chevron, BP, Total, and Repsol-YPF.

Estimates of Venezuelan oil production vary. Venezuela claims its oil production is over 3 million barrels per day, but oil industry analysts and the U.S. Energy Information Administration believe it to be much lower. In addition to other reporting irregularities, much of its production is extra-heavy oil, which may or may not be included with conventional oil in the various production estimates. The U.S. Energy Information Agency estimated Venezuela’s oil production in December 2006 was only 2.5 million barrels per day, a 24% decline from its peak of 3.3 million in 1997.[16]

Hugo Chávez, the President of Venezuela sharply diverged from previous administrations’ economic policies, terminating their practice of extensively privatizing Venezuela’s state-owned holdings, such as the oil sector.[17] Chávez also worked to reduce Venezuelan oil extraction in the hopes of garnering elevated oil prices and, at least theoretically, elevated total oil revenues, thereby boosting Venezuela’s severely deflated foreign exchange reserves. He extensively lobbied other OPEC countries to cut their production rates as well. As a result of these actions, Chávez became known as a “price hawk” in his dealings with the oil industry and OPEC. Chávez also attempted a comprehensive renegotiation of 60-year-old royalty payment agreements with oil giants Philips Petroleum and ExxonMobil.[18] These agreements had allowed the corporations to pay in taxes as little as 1% of the tens of billions of dollars in revenues they were earning from the Venezuelan oil they were extracting. Afterwards, a frustrated Chávez stated his intention to complete the nationalization of Venezuela’s oil resources. Although unsuccessful in his attempts to renegotiate with the oil corporations, Chávez succeeded in improving both the fairness and efficiency of Venezuela’s formerly lax tax collection and auditing system, especially for major corporations and landholders.

Recently, Venezuela has pushed the creation of regional oil initiatives for the Caribbean (Petrocaribe), the Andean region (Petroandino), and South America (Petrosur), and Latin America (Petroamerica). The initiatives include assistance for oil developments, investments in refining capacity, and preferential oil pricing. The most developed of these three is the Petrocaribe initiative, with 13 nations signing a preliminary agreement in 2005. Under Petrocaribe, Venezuela will offer crude oil and petroleum products to Caribbean nations under preferential terms and prices, with Jamaica as the first nation to sign on in August 2005.

Pipeline diplomacy petroleum

The Baku-Tbilisi-Ceyhan pipeline was built to transport crude oil and the Baku-Tbilisi-Erzurum pipeline (South Caucasus Pipeline) was built to transport natural gas from the western side of the Caspian Sea to the Mediterranean Sea bypassing Russian pipelines and thus Russian control. Following the construction of the pipelines the United States and the European Union proposed extending them by means of the proposed Trans-Caspian Oil Pipeline and the Trans-Caspian Gas Pipeline under the Caspian Sea to oil and gas fields on the eastern side of the Caspian Sea in Turkmenistan and Kazakhstan. In 2007, Russia signed agreements with Turkmenistan and Kazakhstan to connect their oil and gas fields to the Russian pipeline system effectively killing the undersea route.

China has completed the Kazakhstan-China oil pipeline from the Kazakhstan oil fields to the Chinese Alashankou-Dushanzi Crude Oil Pipeline in China. China is also working on the Kazakhstan-China gas pipeline from the Kazakhstan gas fields to the Chinese West-East Gas Pipeline in China.

Petroleum positics holdings US

In 1956, a Shell geophysicist named M. King Hubbert accurately predicted that U.S. oil production would peak in 1970.[1]

Matthew Simmons, an energy investment banker and a former adviser to US president George W. Bush believes that oil production in Saudi Arabia will soon peak, meaning it will not be able to supply the world’s growing energy needs.

In June of 2006, former U.S. president Bill Clinton said in a speech,[2]

“We may be at a point of peak oil production. You may see $100 a barrel oil in the next two or three years, but what still is driving this globalization is the idea that is you cannot possibly get rich, stay rich and get richer if you don’t release more greenhouse gases into the atmosphere. That was true in the industrial era; it is simply factually not true. What is true is that the old energy economy is well organized, financed and connected politically.”

In a 1999 speech, Dick Cheney, the US Vice President and former CEO of Halliburton (one of the world’s largest energy services corporations), said,

“By some estimates there will be an average of two per cent annual growth in global oil demand over the years ahead along with conservatively a three per cent natural decline in production from existing reserves. That means by 2010 we will need on the order of an additional fifty million barrels a day. So where is the oil going to come from?….While many regions of the world offer great oil opportunities, the Middle East with two thirds of the world’s oil and the lowest cost, is still where the prize ultimately lies, even though companies are anxious for greater access there, progress continues to be slow.”[3]

Cheney went on to argue that the oil industry should become more active in politics:

” Oil is the only large industry whose leverage has not been all that effective in the political arena. Textiles, electronics, agriculture all seem often to be more influential. Our constituency is not only oilmen from Louisiana and Texas, but software writers in Massachusetts and specially steel producers in Pennsylvania. I am struck that this industry is so strong technically and financially yet not as politically successful or influential as are often smaller industries. We need to earn credibility to have our views heard.”

Prices of oil

economist of the International Energy Agency expressed his opinion in October 2007 that oil prices will remain high for the foreseeable future. Birol says this is due to rapid increases in demand from the rapidly growing economies of India and China.[16] The ministers of OPEC, meeting in early December 2007, appeared to reach a consensus for high, but stable prices. This price point would deliver consistently high income to the oil producing states, but avoid prices so high that they would depress the economies of the oil consuming nations. A range of 70-80 dollars a barrel was suggested by some analysts to be OPEC’s goal.[17] Major oil exporting countries are rapidly developing and are using more oil domestically. Particularly significant are Indonesia, which no longer exports oil, Mexico and Iran, where projected demand will exceed production in about 5 years, and Russia, which is growing rapidly.[18]

Analysis source rocks petroleum geology

Analysis of source rocks

In terms of source rock analysis, several facts need to be established. Firstly, the question of whether there actually is any source rock in the area must be answered. Delineation and identification of potential source rocks depends on studies of the local stratigraphy, palaeogeography and sedimentology to determine the likelihood of organic-rich sediments having been deposited in the past.

If the likelihood of there being a source rock is thought to be high, the next matter to address is the state of thermal maturity of the source, and the timing of maturation. Maturation of source rocks (see diagenesis and fossil fuels) depends strongly on temperature, such that the majority of oil generation occurs in the 60° to 120°C range. Gas generation starts at similar temperatures, but may continue up beyond this range, perhaps as high as 200°C. In order to determine the likelihood of oil/gas generation, therefore, the thermal history of the source rock must be calculated. This is performed with a combination of geochemical analysis of the source rock (to determine the type of kerogens present and their maturation characteristics) and basin modelling methods, such as back-stripping, to model the thermal gradient in the sedimentary column.

Uses of Gas Oil

Us Petroleum Holdings Oil has many uses; it heats homes and businesses and fuels trucks, ships and some cars. A small amount of electricity is produced by diesel, but it is more polluting and more expensive than natural gas. It is often used as a backup fuel for peaking power plants in case the supply of natural gas is interrupted or as the main fuel for small electrical generators. In Europe the use of diesel is generally restricted to cars (about 40%), SUVs (about 90%), and trucks (virtually all). The market for home heating using fuel oil, called heating oil, has decreased due to the widespread penetration of natural gas. However, it is very common in some areas, such as the Northeastern United States.

Residual fuel oil is less useful because it is so viscous that it has to be heated with a special heating system before use and it contains relatively high amounts of pollutants, particularly sulfur, which forms sulfur dioxide upon combustion. However, its undesirable properties make it very cheap. In fact, it is the cheapest liquid fuel available. Since it requires heating before use, residual fuel oil cannot be used in road vehicles, boats or small ships, as the heating equipment takes up valuable space and makes the vehicle heavier. Heating the oil is also a delicate procedure, which is inappropriate to do on small, fast moving vehicles. However, power plants and large ships are able to use residual fuel oil.

Residual fuel oil was used more frequently in the past. It powered boilers, railroad locomotives and steamships. Locomotives now use diesel, steamships are still used however are not as common as they were previously due to their higher operating costs, (most LNG carriers use steam plants as boil off gas emitted from the cargo can be used as a fuel source), and most boilers now use heating oil or natural gas. However, some industrial boilers still use it and so do a few old buildings, mostly in New York City. Residual fuel’s use in electricity generation has also decreased. In 1973, residual fuel oil produced 16.8% of the electricity in the United States. By 1983, it had fallen to 6.2%, and as of 2005, electricity production from all forms US Petroleum Holdings of petroleum, including diesel and residual fuel, is only 3% of total production. The decline is the result of price competition with natural gas and environmental restrictions on emissions. For power plants, the costs of heating the oil, extra pollution control and additional maintenance required after burning it often outweigh the low cost of the fuel. Burning fuel oil, particularly residual fuel oil, also produces much darker smoke than natural gas, which affects the perception of the plant by the community.

Heavy fuel oils continue to be used in the boiler “lighting up” facility in every coal-fired power plant, of which there are a small number in the UK and dozens in China. Although on an enormous scale, it is analogous to lighting kindling to start a fire – without performing this simple function it is difficult to begin the large-scale combustion process.

The chief drawback to residual fuel oil is its high initial viscosity, particularly in the case of No. 6 oil, which requires a correctly engineered system for storage, pumping, and burning. Though it is still usually lighter than water (with a specific gravity usually ranging from 0.95 to 1.03) it is much heavier and more viscous than No. 2 oil, kerosene, or gasoline. No. 6 oil must, in fact, be stored at around 100°F (37.8°C) heated to 150°F (65.6°C)–250°F (121.1°C) before it can be easily pumped, and in cooler temperatures it can congeal into a tarry semisolid. The flash point of most blends of No. 6 oil is, incidentally, about 150°F (65.6°C). Attempting to pump high-viscosity oil at low temperatures was a frequent cause of damage to fuel lines, furnaces, and related equipment which were often designed with lighter fuels in mind.

(For comparison, BS2869 Class G Heavy Fuel Oil behaves in similar fashion, requiring storage at 104°F (40°C), pumping at around 122°F (50°C) and finalising for burning at around 194°F (90°C) / 248°F (120°C).)

Most of the facilities which historically burned No. 6 or other residual oils were industrial plants and similar facilities constructed in the early or mid 20th century, or which had switched from coal to oil fuel during the same time period. In either case, residual oil was seen as a good prospect because it was cheap and readily available, even though it provided less energy per litre than lighter fuels. Most of these facilities have subsequently been closed and demolished, or have replaced their fuel supplies with a simpler one such as gas or No. 2 oil. The high sulfur content of No. 6 oil– up to 3% by weight in some extreme cases– had a corrosive effect on many heating systems (which were usually designed without adequate corrosion protection in mind), shortening their lifespans and increasing the polluting effects. This was particularly the case in furnaces that were regularly shut down and allowed to go cold; the internal condensation produced sulfuric acid.

Environmental cleanups at such facilities are frequently complicated by the use of asbestos insulation on the fuel feed lines. No. 6 oil is very persistent, and does not degrade rapidly. Its viscosity and stickiness also make remediation of underground contamination very difficult, since it reduces the effectiveness of methods such as air-stripping.

When released into water, such as a river or ocean, residual oil tends to break up into patches or tarballs– mixtures of oil and particulate matter such as silt and floating organic matter- rather than form a single slick. An average of about 5-10% of the material will evaporate within hours of the release, primarily the lighter hydrocarbon fractions. The remainder will then often sink to the bottom of the water column.

Alternative methods petroleum extraction

Alternative methods

During the oil price increases of 2004-2008, alternatives methods of producing oil gained importance. The most widely known alternatives involve extracting oil from sources such as oil shale or tar sands. These resources exist in large quantities; however, extracting the oil at low cost without excessively harming the environment remains a challenge.

It is also possible to chemically transform methane or coal into the various hydrocarbons found in oil. The best-known such method is the Fischer-Tropsch process. It was a concept pioneered in Nazi Germany when imports of petroleum were restricted due to war and Germany found a method to extract oil from coal. It was known as Ersatz (English:”substitute”) oil, and accounted for nearly half the total oil used in WWII by Germany. However, the process was used only as a last resort as naturally occurring oil was much cheaper. As crude oil prices increase, the cost of coal to oil conversion becomes comparatively cheaper. The method involves converting high ash coal into synthetic oil in a multi-stage process. Ideally, a ton of coal produces nearly 200 liters (1.25 bbl, 52 US gallons) of crude, with by-products including tar.^{[citation needed]}

Currently, two companies have commercialised their Fischer-Tropsch technology. Shell in Bintulu, Malaysia, uses natural gas as a feedstock, and produces primarily low-sulfur diesel fuels. ^[8] Sasol ^[9] in South Africa uses coal as a feedstock, and produces a variety of synthetic petroleum products.

The process is today used in South Africa to produce most of the country’s diesel fuel from coal by the company Sasol. The process was used in South Africa to meet its energy needs during its isolation under Apartheid. This process produces low sulfur diesel fuel ; it also is an increased threat to environment, as it produces large amounts of greenhouse gases.

An alternative method of converting coal into petroleum is the Karrick process, which was pioneered in the 1930s in the United States. It uses high temperatures in the absence of ambient air, to distill the short-chain hydrocarbons of petroleum out of coal.

More recently explored is thermal depolymerization (TDP), a process for the reduction of complex organic materials into light crude oil. Using pressure and heat, long chain polymers of hydrogen, oxygen, and carbon decompose into short-chain petroleum hydrocarbons. This mimics the natural geological processes thought to be involved in the production of fossil fuels. In theory, TDP can convert any organic waste into petroleum.
