Natural-gas processing Natural-gas processing Natural-gas processing is a complex industrial process designed to clean raw natural gas by separating impurities and various non-methane hydrocarbons and fluids to produce what is known as "pipeline quality" dry natural gas. Natural-gas processing begins at the well head. The composition of the raw natural gas extracted from producing wells depends on the type, depth, and location of the underground deposit and the geology of the area. Oil and natural gas are often found together in the same reservoir. The natural gas produced from oil wells is generally classified as "associated-dissolved", meaning that the natural gas is
Natural gas long distance, high volume transportation of natural gas, whereas pipeline is preferred for transport for distances up to over land and approximately half that distance offshore. CNG is transported at high pressure, typically above . Compressors and decompression equipment are less capital intensive and may be economical in smaller unit sizes than liquefaction/regasification plants. Natural gas trucks and carriers may transport natural gas directly to end-users, or to distribution points such as pipelines. In the past, the natural gas which was recovered in the course of recovering petroleum could not be profitably sold, and was simply burned at the oil
