The oil

Oil is formed in sedimentary rocks because of the decomposition of organic materials. It is required that the rocks in which they form rocks are permeable to allow the oil to flow through them easily when they are formed. Examples include limestone and sandstone. which prevent oil from spreading between adjacent rocks or leakage to the surface of the earth, and there is most of the world 's oil reserves in the continental areas of the shelf , which occupies approximately 26 million km 2 , consisting of about 15 million km 2 of them from a sedimentary basins containing oil reserves. [1]

Seismic surveys are usually used to determine the structure of the continental shelf rocks, and is an initial method that contributes to the detection of areas where oil may be found and can be drilled, while exploration on the sea floor depends on the use of a ship interested in withdrawing a network containing several sound probes called the shipment Explosive; where its sensors reveal waves reflected from the layers of the sea's substrate to form an audio image of the geological formations. After the completion of the detection of geological structures in which oil is expected to be found, exploratory drilling operations begin. It is worth noting that many m These structures can contain stocks of oil, gas or water at several non-economic levels. [1]

The world's ten richest countries are in oil

Each oil country is characterized by a set of characteristics that are related to the nature of their oil reserves , and below comes information on the ten most oil-rich countries: [2]
  • Venezuela: Venezuela possesses 300,878 million barrels of world oil reserves , and it is the country with the richest oil reserves among the countries of the world. North America in terms of the costs of extracting oil and the capital needed to do so.
  • Saudi Arabia: It possesses about 266,455 million barrels of oil , and it can be said that it possesses about one fifth of the world's oil reserves, and the Kingdom of Saudi Arabia is distinguished by the fact that all oil wells in it can extract oil from it by traditional methods. It is reported that there are expectations that the Kingdom of Saudi Arabia will surpass Venezuela in the oil reserves. According to the American Geological Survey, there are more than 100 million barrels located under the barren sands of the Saudi desert, and it has not been discovered yet.
  • Canada: It has about 169,709 million barrels of oil , and the most easily extractable is in the province of Alberta. Oil in Canada with a low density and above is extracted, because the oil extraction process requires large capital and large labor; therefore production is usually Canada's oil is sporadic, not in fixed quantities, and at times when the price of oil is high.
  • Iran: It possesses reserves of oil amounting to 158,400 million barrels, and this makes it one of the oil-rich countries among the countries of the world. Oil was produced in Iran for the first time in the year 1908 AD. It is estimated that Iranian oil will last for 100 years and more, based on its current extraction rate, and Iranian oil is distributed It has about 150 hydrocarbon fields and contains large quantities of crude oil and natural gas. Iran is located after Venezuela and Saudi Arabia in terms of the ease of extracting oil.
  • Iraq: It has 142,503 million barrels of oil reserves , and it can be said that the data used in determining Iraqi oil reserves go back to three decades.
  • Kuwait: It has 101,500 million barrels of global oil reserves, and although its area is small, it contains large quantities of oil, specifically in the Burgan field, which contains about 70 billion barrels of oil, and is the second largest oil field in the world. It is reported that there is a quantity of oil reserves in the common area between Kuwait and Saudi Arabia.
  • The United Arab Emirates: It has about 97,800 million barrels of global oil reserves and most of it is located in the Zakum oil field, and contains about 66 billion barrels of oil and is the third largest oil field after the Ghawar field in Saudi Arabia, and the Burgan field in Kuwait, and since the discovery of oil in the Emirates The United Arab Emirates in 1958 has become a modern country whose standard of living is increasing day by day.
  • Russia: It owns 80,000 million barrels of oil , and is a country rich in natural resources used in energy production, especially the huge oil reserves found in the Siberian plains, and Russian oil production witnessed a significant decline after the collapse of the Soviet Union, but it has developed its oil production in the past few years, Its oil and gas reserves are expected to increase in the future, with continued search and exploration under the ice and polar regions.
  • Libya: It owns 48,363 million barrels of world oil reserves, and Libya's reserves are the largest in Africa, and oil accounts for about 98% of the Libyan government's revenue.
  • The United States of America: Owns about 39,230 million barrels of global oil reserves , which is a very simple part compared to other countries such as Canada and the Kingdom of Saudi Arabia, and the United States of America has increased oil reserves recently due to the use of new, unconventional methods in drilling and exploration for Oil enabled it to extract more gas and shale oil, and as a result the United States' reserves exceeded 36,000 million barrels in 2012, and that was the first time since 1975.

The nature of the places where the oil is

The deposits in which the oil resides are classified into surface and subsurface assets, and a simplified explanation for each of them comes: [3]
  • Surface assets: represents the main source of oil, which gave it great importance in the past, in addition to the fact that many places producing oil were discovered near these assets, and surface assets include two types; the active (living) assets, such as springs, sidewalks, volcanoes and mud flows, and assets Fossil (dead) like wilted sediments, sediments impregnated with bitumen, in addition to solid bitumen that fills the incisors, and here are detailed information about them:
    • Triggers, springs, and effluents: Exhausted oil from one of them reaches the surface, through slow infiltration of reservoirs close to the surface, and through cracks, cracks, spacers, or porous holes in the rocks.
    • Volcanoes and mud flow: its surface is a hill or mound with an opening at the top from which mud or water comes out, and these parts represent flows of gas under great pressure, and when the gas flows, it carries water, sand, mud, and sometimes oil.
    • Solid and semi-solid deposits: It includes a mixture of solid or liquid hydrocarbons that accept ignition, as well as sticky and soluble in carbon disulfide, and solid oil detectors are often found in rocks in the form of veins, or emitted sediments that fill the cracks, and the emitted deposits can be defined as sediments containing oil in the form of heavy oil or bitumen or asphalt.
  • Sub-surface assets: It is divided into oil pools, oil fields, and oil provinces, and the following provides information on each of them:
    • Ponds: These are oil deposits that are located under the surface of the earth in a separate natural oil tank, usually porous, or sandstone.
    • Fields: They are formed from one pool or two pools or more, and they often belong to the same geological structure. As for the pools that differ from each other, they are usually separate.
    • Districts: They are areas consisting of fields and ponds, and the term boycott is usually called the areas with large production, such as the Gulf of Suez, and the Arab Gulf regions.
