Types of Reservoir Drives
Types of Reservoir Drives The reservoir drive mechanism supplies the energy that moves the hydrocarbon located in a reservoir container toward the wellbore as fluid is removed near the wellbore. There are five common drive mechanisms: Water drive, Gas expansion, Solution gas, Rock or compaction drive, Gravity drainage One type usually dominates, but drive types can occur in combination. Depending on the drive mechanism, characteristic recovery efficiencies can be expected for a given reservoir. 1. Oil reservoirs. a. Solution gas drive. b. Gas cap drive. c. Water drive. d. Gravity drainage drive. e. Combination drive. 2. Gas reservoirs. a. Volumetric (gas expansion) drive b. Water drive c. ...
