Natural gas rig

Oil and natural gas are produced by the same geological process: anaerobic decay of organic matter deep under the Earth's surface. As a consequence, oil and natural gas are often found together. In common usage, deposits rich in oil are known as oil fields, and deposits rich in natural gas are called natural gas fields. Download high resolution version (1057x1050, 731 KB)Natural gas rig. ...

Natural gas (commonly refered to as gas in many countries) is a gaseous fossil fuel consisting primarily of methane. ... Anaerobic is a technical word which literally means without air. ... Decomposition is the reduction of bodies and other formerly living organisms into simpler forms of matter; and most particularly to the fate of the body, after death. ... Organic has several meanings and related topics. ...

In general, organic sediments buried in depths of 1,000 m to 6,000 m (at temperatures of 65 °C to 150 °C) generate oil, while sediments buried deeper and at higher temperatures generate natural gas. The deeper the source, the "drier" the gas (that is, the smaller the proportion of condensates in the gas). Because both oil and natural gas are lighter than water, they tend to rise from their sources until they either seep to the surface or are trapped by a non-permeable layer of rock. They can be extracted from the trap by drilling. The metre is the basic unit of length in the International System of Units (SI: Système International dUnités). ... The degree Celsius (°C or ℃ (Unicode 0x2103)) is a unit of temperature named after the Swedish astronomer Anders Celsius (1701–1744), who first proposed a similar system in 1742. ... Natural Gas Condensate (usually just condensate) is a by-product of natural gas. ...
