Reservoir drive mechanism

Reservoir drive mechanism




Is asource of energy for driving the fluids out through the wellbore

Primary recovery

Primary recovery refer to the production of oil and gas from areservoir without use of any process such as fluid injection to supplement the natural energy of the reservoir

 Primary recovery mechanism

There are six driving mechanisms for oil recovery
Reservoir drive mechanism

Rock and fluid expansion drive mechanism

Reservoir drive mechanism

 Can be difined as the mechanism wherein the displacement of oil from the formation to the 
production wells is accomplished by rock and fluid expansion

Characteristics of rock and fluid expansion drive mechanism

Very rapid decline in pressure 

  Constant gas oil ratio that is equal the gas solubility at the bubble point pressure

Nil water production

Ultimate recovery factor is less than 5%
