43+ Natural Gas Extraction Methods US. Sometimes just gas), is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide. Natural reservoir drives include natural gas expansion, gravity drainage of oil from upper parts of a well to lower parts, and displacement of oil by water.
The hydrocarbons associated with oil and natural gas extraction are generally thought to be of lower health risk than many of the contaminants found in or associated with oil and gas production.
Natural gas plays a key role in our nation's clean energy future. Gas hydrates as the fuel problem solution. Natural gas from shale is gathered by a natural gas extraction method commonly referred to as hydraulic fracturing, or fracking. Absorption is usually performed using triethyleneglycol sorbent (teg).
