Hydrocarbon exploration is the search by petroleum geologists and geophysicists for deposits of hydrocarbons, particularly petroleum and natural gas, in the Earth's crust using petroleum geology.
North Sea oil is a mixture of hydrocarbons, comprising liquid petroleum and natural gas, produced from petroleum reservoirs beneath the North Sea.
Petroleum Revenue Tax (PRT) is a direct tax collected in the United Kingdom. It was introduced under the Oil Taxation Act 1975, soon after Harold Wilson's Labour government returned to power and in the immediate aftermath of the 1973 energy crisis, and was intended to ensure "fairer share of profits for the nation" from the exploitation of the UK's continental shelf, while ensuring a "suitable return" on the capital investment by oil companies.
Exploration for petroleum in the Arctic is expensive and challenging both technically and logistically. In the offshore, sea ice can be a major factor. There have been many discoveries of oil and gas in the several Arctic basins that have seen extensive exploration over past decades but distance from existing infrastructure has often deterred development. Development and production operations in the Arctic offshore as a result of exploration have been limited, with the exception of the Barents and Norwegian seas. In Alaska, exploration subsequent to the discovery of the Prudhoe Bay oilfield has focussed on the onshore and shallow coastal waters.
Offshore drilling is a mechanical process where a wellbore is drilled below the seabed. It is typically carried out in order to explore for and subsequently extract petroleum that lies in rock formations beneath the seabed. Most commonly, the term is used to describe drilling activities on the continental shelf, though the term can also be applied to drilling in lakes, inshore waters and inland seas.
Atlantic Petroleum P/FP/F is an oil and gas company situated in Tórshavn, Faroe Islands and has technical offices located in London and Bergen (Norway). It participates in exploration on the Faroese Continental Shelf, offshore Norway, Ireland, and United Kingdom. The company has production from three fields in the United Kingdom's sector of the North Sea and also participates in development projects.
The UK Continental Shelf (UKCS) is the region of waters surrounding the United Kingdom, in which the country has mineral rights. The UK continental shelf includes parts of the North Sea, the North Atlantic, the Irish Sea and the English Channel; the area includes large resources of oil and gas. The UK continental shelf is bordered by Norway, Denmark, Germany, the Netherlands, Belgium, France, and the Republic of Ireland. A median line, setting out the domains of each of these nations, was established by mutual agreement between them: - see the Continental Shelf Act 1964.
The petroleum industry in Western Australia is the largest contributor to the country's petroleum exports. Western Australia's North West Shelf (NWS) is the primary location from which production originates. Oil exports are shipped from Port Hedland.
Offshore oil and gas in the United States provides a large portion of the nation’s oil and gas supply. Large oil and gas reservoirs are found under the sea offshore from Louisiana, Texas, California, and Alaska. Environmental concerns have prevented or restricted offshore drilling in some areas, and the issue has been hotly debated at the local and national levels.
Offshore drilling for oil and gas on the Atlantic coast of the United States took place from 1947 to the early 1980s. Oil companies drilled five wells in Atlantic Florida state waters and 51 exploratory wells on federal leases on the outer continental shelf of the Atlantic coast. None of the wells were completed as producing wells. All the leases have now reverted to the government.
The oil and gas industry plays a central role in the economy of the United Kingdom. Oil and gas account for more than three-quarters of the UK's total primary energy needs. Oil provides 97 per cent of the fuel for transport, and gas is a key fuel for heating and electricity generation. Transport, heating and electricity each account for about one-third of the UK's primary energy needs. Oil and gas are also major feedstocks for the petrochemicals industries producing pharmaceuticals, plastics, cosmetics and domestic appliances.
Petroleum licensing or exploration license is the act of giving licenses to a company or a joint venture allowing them to search for commercially feasible deposits for the extraction of petroleum.
The Oil Taxation Act 1975 is a UK Act of Parliament relevant for UK enterprise law that was intended to ensure that oil and gas extraction companies operating in British territories and waters paid their fair share of tax. Over many years of amendments it was largely eliminated over 2015 and 2016, as the Petroleum Revenue Tax was cut to zero.
The Oil and Gas (Enterprise) Act 1982 is an Act of the Parliament of the United Kingdom which started the process of privatisation of the oil and gas industries in the UK. It empowered the government to float off and sell shares in Britoil the upstream production side of the British National Oil Corporation. It ended the British Gas Corporation’s monopoly on the transportation and supply of gas, opening up the gas market to other gas suppliers. The Act made miscellaneous provisions relating to the oil and gas industries concerning Petroleum Licences and Offshore Installations.
The Petroleum and Submarine Pipe-lines Act 1975 was an act of the Parliament of the United Kingdom which addressed the licensing, ownership, exploitation, production, transportation, processing and refining of petroleum and petroleum products in the UK. Enacted in 1975 when the UK’s first North Sea oil was produced, the act aimed to provide greater public control of the oil industry. The act established the British National Oil Corporation and a National Oil Account; modified the conditions of petroleum licences; controlled the construction and use of underground pipelines; and controlled the development of oil refineries.
The Petroleum Act 1987 is an Act of the Parliament of the United Kingdom which updates the arrangements for regulating offshore installations and their operation. In particular it makes provisions for the licensing and the safe and orderly abandonment of installations and submarine pipelines.
The Petroleum Revenue Tax Act 1980 is a UK act of Parliament associated with UK enterprise law that made new provisions for petroleum revenue tax. The act required that payments on account of tax should be made in advance of an assessment, and that interest payable on tax was brought forward.
The Petroleum Royalties (Relief) Act 1983 is an Act of the Parliament of the United Kingdom which exempted certain petroleum licence holders of new offshore oil and gas fields from the payment of petroleum royalties or the delivery of petroleum.
The Offshore Petroleum Development (Scotland) Act 1975 is an Act of the Parliament of the United Kingdom which facilitated the onshore construction of offshore oil platforms for the UK Continental Shelf. Its provisions permitted the acquisition of land; the regulation of sea-based operations; the granting of licences for construction; the reinstatement of land; and financial provisions.
