Petroleum reservoir - Wikipedia
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 …
Oil and gas reservoir - Energy Education
An oil and gas reservoir is a formation of rock in which oil and natural gas has accumulated. The oil and gas collected in small, connected pore spaces of rock and are trapped within the reservoir by adjacent and overlying, impermeable layers of rock.
List of countries by proven oil reserves - Wikipedia
Proven oil reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated, with a high degree of confidence, to be commercially recoverable from a given date forward from known reservoirs …
Oil reserves - Our World in Data
2024年6月20日 · Shown are the total proven reserves of oil, in tonnes. This is oil that we know with reasonable certainty can be recovered in the future under existing economic and operating conditions.

Petroleum Reservoirs - an overview | ScienceDirect Topics
Oil reservoirs: If the reservoir temperature, T, is less than the critical temperature, T c, of the reservoir fluid, the reservoir is classified as an oil reservoir. 2. Gas reservoirs: If the reservoir temperature is greater than the critical temperature of the hydrocarbon fluid, the reservoir is considered a gas reservoir.
