n: a combination of two or more natural energies that work together in a reservoir to force fluids into a wellbore. Possible combinations include gas-cap and water drive, solution gas and water drive, and gas-cap drive and gravity drainage.

the solution gas associated with produced fluids.

n: the factor that is used to convert stock tank barrels of oil to reservoir barrels. It is the ratio between the space occupied by a barrel of oil containing solution gas at reservoir conditions and a barrel of dead oil at surface conditions. Also called reservoir volume factor.

n: a measure of the volume of gas produced with oil, expressed in cubic feet per barrel or cubic metres per tonne. Also called solution gas-oil ratio.

n: a measure of the volume of gas produced with the oil. it is expressed in cubicfeet per barrel.

the number of standard cubic feet of gas contained in a barrel of oil.

breakout of gas from a liquid, normally at the point where the pressure has declined sufficiently to allow solution gas to be released as bubbles.

one of several reservoir drive methods including volumetric, depletion, gravity, gas cap, solution gas expansion, water drive, etc.

n: 1. a decrease in oil volume caused by evaporation of solution gas or by lowered temperature. 2. the suction in volume or heating value of a gas stream due to removal of some of its constituents. 3. the unaccounted loss of products from storage tanks.

n: lighter hydrocarbons that exist as a liquid under reservoir conditions but that effervesce as gas when pressure is released during production.

n: Dissolved gas in wellbore or reservoir fluids. The gas will remain in solution until the pressure or temperature conditions change, at which time it may break out of solution to become free gas.

the natural gas that is dissolved in a crude oil.

a drive mechanism where a drop in pressure releases gas from the oil that helps drive the oil towards the wellbore. It is a poor recovery mechanism.
