Thomas Gold used the term "the deep hot biosphere" to describe the microbes which live underground. [6] This hypothesis is different from biogenic oil in that the role of deep-dwelling microbes is a biological source for oil which is not of a sedimentary origin and is not sourced from surface carbon.
Operated by Shell, with JV partners Chevron (37.5%) and BP (27.5%), the spar acts as a hub for and enables development of three fields Great White, Tobago, and Silvertip. The oil and gas fields beneath the platform lie in a geological formation holding resources estimated at 3–15 billion barrels of oil equivalent according to a report by the BSEE, formerly known as the MMS.
An oil field with dozens of wells. This is the Summerland Oil Field, near Santa Barbara, California, before 1906 Eagle Ford Shale flares visible from space (green and infrared wavelengths), in the arc between "1" and "2", amid cities in southeast Texas in 2012.
Petroleum, or evidence of its immediate occurrence, can be found on the surface of the Earth. Oil seeps can be found near a fault zone, where the movement of Earth's crust can expose petroleum source rock, and thus the crude oil itself. [15] They can also be found on the ocean floor, and can be found using satellite imaging. [16]
Today geochemistry serves the petroleum industry by helping seek out effective petroleum systems. The use of geochemistry is relatively cost-effective that allows geologists to assess reservoir-related issues. Once oil to source rock correlation is found, petroleum geologists will use this information to render a 3D model of the basin.

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.
Some statistics on this page are disputed and controversial—different sources (OPEC, CIA World Factbook, oil companies) give different figures. Some of the differences reflect different types of oil included. Different estimates may or may not include oil shale, mined oil sands or natural gas liquids.
