Gas Cap Drive Mechanism

Gas Cap Drive Mechanism. A gas cap expansion drive reservoir is a gas cap reservoir in which the expanding gas cap is responsible for the majority of the gas expansion A gas cap is a free gas zone that overlies an oil zone The freegas zone may be preexisting or may form during the depletion process Preexisting gas caps are called primary gas caps Gas caps that are not originally.

Gas expansion is the primary drive mechanism in most conventional gas reservoirs Again the analogy of a gasfilled balloon a very appropriate analogy If a balloon is filled with high pressure gas and the end is opened to the low pressure atmosphere then.

PDF fileOil recovery by gas cap expansion is actually a frontal drive displacing mechanism which therefore yields considerably larger recovery efficiency than that of depletion drive reservoirs The expected oil recovery ranges from 20% to 40% The ultimate oil recovery from a gas cap drive reservoir will vary depending.

In solution gas drive much of the driving gas is produced a gas cap for thea fluid remains till later in the life of but The with pressure drop the gas reservoir cap system therefore declines slowly over the years The decline will depend on the relative size of the gas cap to the oil accumulation.
