Natural-gas liquids (NGL) are hydrocarbons that exist as gas in the reservoir but become liquid at surface pressure and temperature conditions. They are the liquid content of [[natural gas]] that is recovered separately at the surface in lease separators and field facilities or in natural-gas processing plants. The liquids recovered at the well or at small gas-oil separators in the field are called [[lease condensate]] (the liquids recovered at natural-gas wells or at small gas/oil separators in the field; also called [[field condensate]]) and consist primarily of [https://en.wikipedia.org/wiki/Pentane pentanes] and heavier hydrocarbons. Those obtained from processing natural gas at natural-gas processing plants are called [[natural-gas plant liquids]] or [[liquefied petroleum gasses]] and consist primarily of ethane, propate, butane, and isobutane.

The content of NGL of natural gas varies widely from essentially none in [http://www.britannica.com/EBchecked/topic/172274/dry-gas dry gas] to more than 200 bbl of NGL per mmcf (million cubic feet) of gas in rich [http://www.britannica.com/EBchecked/topic/641260/wet-gas wet gas].

Figures for the world's production of NGL are not consistently reported and are, therefore, not easy to obtain. The total amounts of NGL, or of the lease condensate production, or both, are commonly reported as part of the crude oil production, and while production volumes of natural-gas plant liquids are sometimes reported, separate figures for lease condensate production can seldom be obtained.
