What type of gas has a high content of liquid hydrocarbon at pressures and temperatures lower than reservoir conditions?

• A. Associated Gas
• B. Nonassociated Gas
• C. Wet Gas
• D. Gas Condensate

Answer: (D)

When gas is produced from a reservoir and the pressure and temperature fall below the dew point, heavier hydrocarbons begin to condense into liquids. This liquid-rich gas is characteristic of a gas condensate system, where liquids condense out of the gas phase as conditions move below the reservoir dew point. The liquids collected at surface are the condensate, which is why this type of gas is described as having a high content of liquid hydrocarbon at sub-dew-point conditions. The other terms don’t fit this specific behavior as precisely: associated or nonassociated refers to whether the gas is produced with oil or without oil, not to the condensation of liquids; wet gas contains natural gas liquids but not necessarily as condensates formed by crossing the dew point. Gas condensate specifically describes the condensable liquids that appear when pressure and temperature drop beneath the reservoir’s dew point.
