hydrocarbon condensates produced in conjunction with natural gas.

natural gas condensate, usually C2 to C8+. The C5-C8 components condense to a very volatile liquid when the temperature decreases near the wellhead.

condensate gas ratio.

n: a light hydrocarbon liquid obtained by condensation of hydrocarbon vapours. It consists of varying proportions of butane, propane, pentane, and heavier fractions, with little or no methane or ethane.

the part of the hydrocarbon stream that is a vapor in the formation and condenses to a liquid after being cooled. Normally the volatile condensate has a composition of C5 to C8 and an API gravity of >40.

a relative permeability effect where condensate, usually hydrocarbon, drops out of the vapor phase around the wellbore when the pressure drops below the dew point in response to drawdown or depletion. Gas rates can be severely reduced by the permeability

n pi: hydrocarbons that are gaseous in the reservoir but that will separate out in liquid form at the pressures and temperatures at which separators normally operate. Sometimes called distillate.

n: the ratio of the volume of liquid produced to the volume of residue gas produced;usually expressed in barrels per million cubic feet.
