Liquid hydrocarbons produced with natural gas which are separated from it by cooling, expansion, and various other means. Hydrocarbons which are in the gaseous state under reservoir conditions but which become liquid either in passage up the hole or at the surface.

Condensate is the hydrocarbon liquid that is separated from natural gas because of changes in pressure and temperature when the gas from the reservoir was delivered to the surface separators. Typically gas condensates are similar to commercial gasoline with a higher hydrocarbon component “tail” that can extend beyond C30 hydrocarbons.
A mixture of hydrocarbons which are in a gaseous state under their original temperature and pressure in the depths of the reservoir, and which turn into a liquid state during the production process, at ground pressure and temperature
