USPetroleum what is petroleum?
US Petroleum Holdings colaborate with the us definition of Petroleum (Latin Petroleum f. Holdings Latin petra (f. Greek ????? – rock) + Latin oleum (f. Greek ?????? – oil)) or crude oil is a naturally occurring, flammable liquid found in rock formations in the Earth consisting of a complex mixture of hydrocarbons of various lengths, plus other organic compounds. The proportion of hydrocarbons in the mixture is highly variable and ranges from as much as 97% by weight in the lighter oils to as little as 50% in the heavier oils and bitumens.
The hydrocarbons in crude oil are mostly alkanes, cycloalkanes and various aromatic hydrocarbons while the other organic compounds contain nitrogen, oxygen and sulfur, and trace amounts of metals such as iron, nickel, copper and vanadium. The exact molecular composition varies widely from formation to formation but the proportion of chemical elements vary over fairly narrow limits as follows:[1]
| Carbon | 83-87% |
| Hydrogen | 10-14% |
| Nitrogen | 0.1-2% |
| Oxygen | 0.1-1.5% |
| Sulfur | 0.5-6% |
| Metals | <1000 ppm |
Crude oil varies greatly in appearance depending on its composition. It is usually black or dark brown (although it may be yellowish or even greenish). In the reservoir it is usually found in association with natural gas, which being lighter forms a gas cap over the petroleum, and saline water, which being heavier generally floats underneath it. Crude oil may also be found in semi-solid form mixed with sand, as in the Athabasca oil sands in Canada, where it may be referred to as crude bitumen.
Petroleum is used mostly, by volume, for producing fuel oil and gasoline (petrol), both important “primary energy” sources. [2] 84% by volume of the hydrocarbons present in petroleum is converted into energy-rich fuels (petroleum-based fuels), including gasoline, diesel, jet, heating, and other fuel oils, and liquefied petroleum gas. [3]
Due to its high energy density, easy transportability and relative abundance, it has become the world’s most important source of energy since the mid-1950s. Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, and plastics; the 16% not used for energy production is converted into these other materials.
Petroleum is found in porous rock formations in the upper strata of some areas of the Earth’s crust. There is also petroleum in oil sands (tar sands). Known reserves of petroleum are typically estimated at around 140 km³ (1.2 trillion barrels) without oil sands [4], or 440 km³ (3.74 trillion barrels) with oil sands [5]. However, oil production from oil sands is currently severely limited. Consumption is currently around 84 million barrels per day, or 3.6 km³ per year. Because of reservoir engineering difficulties, recoverable oil reserves are significantly less than total oil-in-place. At current consumption levels, and assuming that oil will be consumed only from reservoirs, known reserves would be gone around 2039, potentially leading to a global energy crisis. However, this ignores any new discoveries, rapidly increasing consumption in China, India, and other developing nations; using oil sands, using synthetic petroleum, and other factors which may extend or reduce this estimate.
Uses of Fuel
From Wikipedia
Petroleum, in some form or other, is not a substance new in the world’s history. More than four thousand years ago, according to Herodotus and confirmed by Diodorus Siculus, asphalt was employed in the construction of the walls and towers of Babylon; there were oil pits near Ardericca (near Babylon), and a pitch spring on Zacynthus.[10] Great quantities of it were found on the banks of the river Issus, one of the tributaries of the Euphrates. Ancient Persian tablets indicate the medicinal and lighting uses of petroleum in the upper levels of their society.
The earliest known oil wells were drilled in China in 347 CE or earlier. They had depths of up to about 800 feet (244 m) and were drilled using bits attached to bamboo poles.[11] The oil was burned to evaporate brine and produce salt. By the 10th century, extensive bamboo pipelines connected oil wells with salt springs. The ancient records of China and Japan are said to contain many allusions to the use of natural gas for lighting and heating. Petroleum was known as burning water in Japan in the 7th century. [10]
The Middle East petroleum industry was established by the 8th century, when the streets of the newly constructed Baghdad were paved with tar, derived from easily accessible petroleum from natural fields in the region. In the 9th century, oil fields were exploited in the area around modern Baku, Azerbaijan, to produce naphtha. These fields were described by the geographer Masudi in the 10th century, and by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads. Petroleum was distilled by Persian chemist al-Razi in the 9th century, producing chemicals such as kerosene in the al-ambiq (alembic). [12] (See also: Alchemy (Islam), Islamic science, and Timeline of science and technology in the Islamic world.)
The earliest mention of American petroleum occurs in Sir Walter Raleigh’s account of the Trinidad Pitch Lake in 1595; whilst thirty-seven years later, the account of a visit of a Franciscan, Joseph de la Roche d’Allion, to the oil springs of New York was published in Sagard’s Histoire du Canada. A Russian traveller, Peter Kalm, in his work on America published in 1748 showed on a map the oil springs of Pennsylvania. [10]
In 1711 the Greek physician Eyrini d’Eyrinis discovered asphalt at Val-de-Travers, (Neuchâtel). He established a bitumen mine de la Presta there in 1719 that operated until 1986. [13][14]
Oil sands were mined from 1745 in Merkwiller-Pechelbronn, Alsace under the direction of Louis Pierre Ancillon de la Sablonnière, by special appointement of Louis XV.[15] The Pechelbronn oil field was active until 1970, and was the birth place of companies like Antar and Schlumberger. The first modern refinery was built there in 1857.[15]
The modern history of petroleum began in 1846 with the discovery of the process of refining kerosene from coal by Nova Scotian Abraham Pineo Gesner.
Ignacy ?ukasiewicz improved Gesner’s method to develop a means of refining kerosene from the more readily available “rock oil” (“petr-oleum”) seeps in 1852 and the first rock oil mine was built in Bóbrka, near Krosno in Galicia in the following year. These discoveries rapidly spread around the world, and Meerzoeff built the first Russian refinery in the mature oil fields at Baku in 1861. At that time Baku produced about 90% of the world’s oil.
Oil field in California, 1938.
The first commercial oil well drilled in North America was in Oil Springs, Ontario, Canada in 1858, dug by James Miller Williams. The US petroleum industry began with Edwin Drake’s drilling of a 69-foot (21 m) oil well in 1859, on Oil Creek near Titusville, Pennsylvania, for the Seneca Oil Company (originally yielding 25 barrels a day, by the end of the year output was at the rate of 15 barrels). The industry grew slowly in the 1800s, driven by the demand for kerosene and oil lamps. It became a major national concern in the early part of the 20th century; the introduction of the internal combustion engine provided a demand that has largely sustained the industry to this day. Early “local” finds like those in Pennsylvania and Ontario were quickly outpaced by demand, leading to “oil booms” in Texas, Oklahoma, and California.
Early production of crude petroleum in the United States: [10]
- 1859: 2,000 barrels (~340 t)
- 1869: 4,215,000 barrels (~721,000 t)
- 1879: 19,914,146 barrels (~3,410,000 t)
- 1889: 35,163,513 barrels (~6,020,000 t)
- 1899: 57,084,428 barrels (~9,770,000 t)
- 1906: 126,493,936 barrels (~21,600,000 t)
By 1910, significant oil fields had been discovered in Canada (specifically, in the province of Ontario), the Dutch East Indies (1885, in Sumatra), Iran (1908, in Masjed Soleiman), Peru, Venezuela, and Mexico, and were being developed at an industrial level.
Even until the mid-1950s, coal was still the world’s foremost fuel, but oil quickly took over. Following the 1973 energy crisis and the 1979 energy crisis, there was significant media coverage of oil supply levels. This brought to light the concern that oil is a limited resource that will eventually run out, at least as an economically viable energy source. At the time, the most common and popular predictions were always quite dire, and when they did not come true, many dismissed all such discussion. The future of petroleum as a fuel remains somewhat controversial. USA Today news (2004) reports that there are 40 years of petroleum left in the ground. Some[citation needed] argue that because the total amount of petroleum is finite, the dire predictions of the 1970s have merely been postponed. Others[citation needed] claim that technology will continue to allow for the production of cheap hydrocarbons and that the earth has vast sources of unconventional petroleum reserves in the form of tar sands, bitumen fields and oil shale that will allow for petroleum use to continue in the future, with both the Canadian tar sands and United States shale oil deposits representing potential reserves matching existing liquid petroleum deposits worldwide.
Today, about 90% of vehicular fuel needs are met by oil. Petroleum also makes up 40% of total energy consumption in the United States, but is responsible for only 2% of electricity generation. Petroleum’s worth as a portable, dense energy source powering the vast majority of vehicles and as the base of many industrial chemicals makes it one of the world’s most important commodities. Access to it was a major factor in several military conflicts including World War II and the Persian Gulf Wars of the late twentieth and early twenty-first centuries. The top three oil producing countries are Saudi Arabia, Russia, and the United States. About 80% of the world’s readily accessible reserves are located in the Middle East, with 62.5% coming from the Arab 5: Saudi Arabia (12.5%), UAE, Iraq, Qatar and Kuwait. However, with today’s oil prices, Venezuela has larger reserves than Saudi Arabia due to crude reserves derived from bitumen.
