Upstream regards exploration and extraction of crude oil, midstream encompasses transportation and storage of crude, and downstream concerns refining crude oil into various end products. Petroleum is vital to many industries, and is necessary for the maintenance of industrial civilization in its current configuration, making it a critical ...
Brent crude, the international benchmark, is down over 19% since peaking in the spring. Oversupply would rise to 1.4 million barrels per day in 2025 if OPEC+ follows through on plans to unwind ...
Oil field in California, 1938. The modern history of petroleum began in the nineteenth century with the refining of paraffin from crude oil. The Scottish chemist James Young in 1847 noticed a natural petroleum seepage in the Riddings colliery at Alfreton, Derbyshire from which he distilled a light thin oil suitable for use as lamp oil, at the same time obtaining a thicker oil suitable for ...
In 1956, Hubbert confined his peak oil prediction to that crude oil "producible by methods now in use." [13] By 1962, however, his analyses included future improvements in exploration and production. [14] All of Hubbert's analyses of peak oil specifically excluded oil manufactured from oil shale or mined from oil sands. A 2013 study predicting ...
Petroleum [a] is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons, [1] and is found in geological formations.The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.
The Achnacarry Agreement or "As-Is Agreement" was an early attempt to restrict petroleum production, signed in Scotland on 17 September 1928. [1] The discovery of the East Texas Oil Field in the 1930s led to a boom in production that caused prices to fall, leading the Railroad Commission of Texas to control production.
The oil and gas industry is usually divided into three major sectors: upstream, midstream, and downstream. The downstream sector is the refining of petroleum crude oil and the processing and purifying of raw natural gas, [1] as well as the marketing and distribution of products derived from crude oil and natural gas.
"Hubbert's peak" can refer to the peaking of production in a particular area, which has now been observed for many fields and regions. Hubbert's peak was thought to have been achieved in the United States contiguous 48 states (that is, excluding Alaska and Hawaii) in the early 1970s. Oil production peaked at 10.2 million barrels (1.62 × 10 ^ 6 m 3) per day in 1970 and then dec
