n: the process of gradually lowering elevated ambient pressure to eliminate dissolved gases from a divers blood- stream and tissues.

n: natural gas that is in solution with crude oil in the reservoir.

Oil Ratio: the amount of gas contained in the oil (in std ft3/bbl). This value can change if one fluid is produced faster than the other or if one fluid is re-injected.

the solution gas associated with produced fluids.

a reservoir drive mechanism in which dissolved gas from the crude oil breaks out of solution and provides energy to push the hydrocarbons toward the wellbore.

n: a source of natural reservoir energy in which the dissolved gas coming out of the oil expands to force the oil into the well bore. Also called solution-gas drive. See reservoir drive mechanism.

n: a hydrocarbon that exists in the gaseous phase at reservoir pressure and temperature and remains a gas when produced under normal conditions.

n: 1.The gaseous phase present in a reservoir or other contained area. Gas may be found either dissolved in reservoir fluids or as free gas that tends to form a gas cap beneath the top seal on the reservoir trap. Both free gas and dissolved gas play importan

gas that is not dissolved in the liquid.

n: I. a condition sometimes encountered in a pumping well when dissolved gas, released from solution during the upstroke of the plunger, appears as free gas between the valves. If the gas pressure is sufficient, the standing valve is locked shut, and no fluid enters the tubing. 2. a device fitted to the gauging hatch on a pressure tank that enables manual dipping and sampling without loss of vapour. 3. a condition that can occur when gas-cut mud is circulated by the mud pump. The gas breaks out of the mud, expands, and works against the operation of the piston and valves.

n: the low-pressure area of induction port in pump is filled with departed free gas，which will cause suck inproperly even cutout。

the driving force in the reservoir, usually gas cap, dissolved gas, water drive, gravity, or compaction of sediments.

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.
