Natural Gas

From MoxyWiki

Natural gas is a combustible mixture of hydrocarbon gases. It consists mainly of methane (CH₄), with varying levels of heavier hydrocarbons and other gases such as carbon dioxide.

When accumulated in a subsurface reservoir that can be readily produced, it is known as convential gas. Conventional gas can also be found with oil in oil fields.

Conventional gas can be dry (almost pure methane) or wet (associated with the 'wet gas' components - ethane, propane, butanes and condensate). Dry gas has a lower energy content than wet gas. Natural gas can also be found in more difficult to extract unconventional deposits, such as coal beds (coal seam gas), or in shales (shale gas), low quality reservoirs (tight gas) or as gas hydrates^[1]
