n: see associated gas.

n: natural gas that overlies and contacts crude oil in a reservoir. Where reservoir conditions are such that the production of associated gas does not substantially affect the recovery of crude oil in the reservoir, such gas may also be reclassified as non-associated gas by a regulatory agency. Also called associated free gas. See gas cap.

the natural gas which occurs with crude oil. It may be free or dissolved. When it occurs as free gas, it may be called unassociated gas.

the viscosity of the fluid in the reservoir at the reservoir conditions. Note – associated gas reduces the viscosity of most oils.

n: a free-gas phase overlying an oil zone and occurring within the same producing formation as the oil. See associated gas, reservoir.

n: the free gas phase that is sometimes found overlying an oil zone and occurs within the same formation as the oil.

a zone of free gas above an oil deposit. The gas cap occurs where the oil is oversaturated with gas (past the solubility limit). When a gas cap is not present at discovery, the oil is above the bubble point.

n: see associated gas.

n: natural gas lay on the upper part of crude oil and contact with crude oil。

n: crude oil that contains gas and has not been stabilised or weathered. It can cause gas cutting when added to mud and is a potential fire hazard.

produced oil before removal of associated gas.

bringing a well on with nitrogen lift to get the initial flow rate or to get it to steady state flow. Commonly used after workovers to jet back heavy brines until the hydrocarbons with associated gas flow into the well and begin natural production.

natural gas, not initially dissolved in oil, produced from a reservoir.

gas that occurs without association to oil.
