Rhourde El Baguel Oil Field
Rhourde El Baguel Oil Field (REB) is an oil field located in Ouargla Province, Algeria. It was discovered in 1963 by Edward Chittick under Sinclair International and developed by ARCO (now part of BP) and Sonatrach in 1996. API oil (40.2 Deg) is produced from a Cambrian formation at a depth of . It is the second largest field in Algeria. REB's recovery rate declined to 18% of its maximum by 1995. In 1996, it was producing less than 25,000 barrels per day. On February 15, 1996, ARCO signed a 25-year production sharing contract (PSC) valued at $1.3 billion with Algeria. In 1995 it paid a signature bonus of $225m and agreed to pay a $300m entrance fee. It was to invest in an enhanced oil recovery system and further development, including 38 new wells, but this work did not take place. After acquiring ARCO, BP raised the field's output by gas injection to 85,000 b/d peak for a few months in early 2000. Encouraged by this success, BP decided to increase the pressure of the inject ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ouargla Province
Ouargla or Warqla ( ar, ولاية ورقلة) is a province (''wilaya'') in eastern Algeria. Its capital is Ouargla. Other localities include Hassi Ben Abdellah and Hassi Messaoud. It contains the Issaouane Erg desert. History In the past Ouargla was the center of trading of gold and slaves, as well as being an important center of Ibadi Islam. However, the Ibadis have left for the M'zab valley. In 1984 Illizi Province was carved out of its territory. In 2019, Touggourt Province was carved out of its territory. Administrative divisions The province is divided into 6 districts (''daïras''), which are further divided into 10 ''communes'' or municipalities. Districts Geology The region lies within the Algerian Triassic Sedimentary basin containing numerous oil and gas fields, including the Alrar gas field.Hamouda, A., 1980, Petroleum Potential-Ourgla Region Triassic Basin, Algeria, in Giant Oil and Gas Fields of the Decade: 1968-1978, AAPG Memoir 30, Halbouty, M.T., editor ...

Oil Field
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust. Petroleum reservoirs are broadly classified as ''conventional'' and '' unconventional'' reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs, the rocks have high porosity and low permeability, which keeps the hydrocarbons trapped in place, therefore not requiring a cap rock. Reservoirs are found using hydrocarbon exploration methods. Oil field An oil field is an area of accumulation of liquid oil underground in multiple (potentially linked) reservoirs, trapped as it rises by impermeable rock formations. In industrial terms, an o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ARCO
ARCO ( ) is a brand of gasoline stations currently owned by Marathon Petroleum after BP sold its rights. BP commercializes the brand in Northern California, Oregon and Washington, while Marathon has rights for the rest of the United States and in Mexico. ARCO had been established in 1966 as the "Atlantic Richfield Company", an independent oil and gas company formed after the merger of Atlantic Petroleum and the Richfield Oil Corporation. History From 1966 to 2000, the 'Atlantic Richfield Company', doing business as ARCO, was an independent American oil company with operations in the United States, Indonesia, the North Sea, the South China Sea, and Mexico. After its acquisition of Anaconda Copper Mining Company in 1977, ARCO had owned hard rock mines in several western states, which has created environmental clean-up liabilities to the company to this day even after the mines were closed in the early 1980s. In 2000, BP acquired ARCO for $26.8 billion. ARCO's retail and mark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambrian Formation
The Cambrian Period ( ; sometimes symbolized Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon. The Cambrian lasted 53.4 million years from the end of the preceding Ediacaran Period 538.8 million years ago (mya) to the beginning of the Ordovician Period mya. Its subdivisions, and its base, are somewhat in flux. The period was established as "Cambrian series" by Adam Sedgwick, who named it after Cambria, the Latin name for 'Cymru' ( Wales), where Britain's Cambrian rocks are best exposed. Sedgwick identified the layer as part of his task, along with Roderick Murchison, to subdivide the large "Transition Series", although the two geologists disagreed for a while on the appropriate categorization. The Cambrian is unique in its unusually high proportion of sedimentary deposits, sites of exceptional preservation where "soft" parts of organisms are preserved as well as their more resistant shells. As a result, our understanding of the Cambrian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Production Sharing Contract
Production sharing agreements (PSAs) or production sharing contracts (PSCs) are a common type of contract signed between a government and a resource extraction company (or group of companies) concerning how much of the resource (usually oil) extracted from the country each will receive. Description Production sharing agreements were first used in Bolivia in the early 1950s, although their first implementation similar to today's was in Indonesia in the 1960s. Today they are often used in the Middle East and Central Asia,overall 40 countries worldwide. In production sharing agreements the country's government awards the execution of exploration and production activities to an oil company. The oil company bears the mineral and financial risk of the initiative and explores, develops and ultimately produces the field as required. When successful, the company is permitted to use the money from produced oil to recover capital and operational expenditures, known as "cost oil". The rem ...

Enhanced Oil Recovery
Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted otherwise. EOR can extract 30% to 60% or more of a reservoir's oil, compared to 20% to 40% using primary and secondary recovery. According to the US Department of Energy, carbon dioxide and water are injected along with one of three EOR techniques: thermal injection, gas injection, and chemical injection. More advanced, speculative EOR techniques are sometimes called quaternary recovery. Methods There are three primary techniques of EOR: gas injection, thermal injection, and chemical injection. Gas injection, which uses gases such as natural gas, nitrogen, or carbon dioxide (CO2), accounts for nearly 60 percent of EOR production in the United States. Thermal injection, which involves the introduction of heat, accounts for 40 percent of EOR production in the United States, with most of it occurring in California. Chemical injection, ...

Gas Injection
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colourless gas invisible to the human observer. The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehe ...

Arbitration
Arbitration is a form of alternative dispute resolution (ADR) that resolves disputes outside the judiciary courts. The dispute will be decided by one or more persons (the 'arbitrators', 'arbiters' or 'arbitral tribunal'), which renders the 'arbitration award'. An arbitration decision or award is legally binding on both sides and enforceable in the courts, unless all parties stipulate that the arbitration process and decision are non-binding. Arbitration is often used for the resolution of commercial disputes, particularly in the context of international commercial transactions. In certain countries such as the United States, arbitration is also frequently employed in consumer and employment matters, where arbitration may be mandated by the terms of employment or commercial contracts and may include a waiver of the right to bring a class action claim. Mandatory consumer and employment arbitration should be distinguished from consensual arbitration, particularly commercial ...

Proven Reserves
Proven reserves (also called measured reserves, 1P, and reserves) is a measure of fossil fuel energy reserves, such as oil reserves, natural gas reserves, and coal reserves. It is defined as the " antity of energy sources estimated with reasonable certainty, from the analysis of geologic and engineering data, to be recoverable from well established or known reservoirs with the existing equipment and under the existing operating conditions." A reserve is considered proven if it is probable that at least 90% of the resource is recoverable by economically profitable means. Operating conditions are taken into account when determining if a reserve is classified as proven. Operating conditions include operational break-even price, regulatory and contractual approvals, without which the reserve cannot be classified as proven. Price changes therefore can have a large impact on the classification of proven reserves. Regulatory and contractual conditions may change, and also affect the am ...
