Gas Cap Drive Mechanism

Gas Cap Drive Mechanism. 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.

Gas cap drive can account for up to 30 percent recovery of the STOOIP depending on the size of the original gas cap Gravity drainage is another drive mechanism that can occur in both saturated and undersaturated oil reservoirs.

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.

GasCap an overview ScienceDirect Topics

Recovery can sometimes be improved with completion strategies that conserve reservoir energy by minimizing the producing GOR gasoil ratio Gas cap drive In a gas cap drive reservoir the primary source of reservoir energy is an initial gas cap which expands as the reservoir pressure drops Additional energy is provided by the expansion of solution gas.

RE: Drive Mechanism Index Gas Cap Drive YouTube

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.
