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 etc.). Quantities of natural gas are measured in normal cubic meters (cubic meter of gas at "normal" temperature and pressure ) or standard cubic feet (cubic foot of gas at "standard" temperature and pressure ), . The gross heat of combustion of commercial quality natural gas is around , but this can vary by several percent. This is about (assuming a density of , an approximate value). Gas prices for end users vary greatly across the EU. A single European energy market, one of the key objectives of the EU, should level the prices of gas in all EU member
