• Pressure maintenance

  Repressuring of an oil-field to maintain original pressure. the use of water flooding or natural gas recycling during primary recovery to provide additional formation pressure and displacement energy that can supplement and conserve natural reservoir drives. although commonly begun during primary production, pressure maintenance methods are often considered to be a form of enhanced oil...

• Reservoir drive mechanism

  The process in which reservoir fluids are caused to flow out of the reservoir rock and into a wellbore by natural energy. gas drives depend on the fact that, as the reservoir is produced, pressure is reduced, allowing the gas to expand and provide the driving energy. water-drive reservoirs depend on water pressure to force...

• Improved oil recovery or ior

  Any of various methods, chiefly reservoir drive mechanisms and enhanced recover techniques, designed to improve the flow of hydrocarbons from the reservoir to the wellbore or to recover more oil after the primary and secondary methods (water and gas floods) are uneconomic....

• Flowing well

  A well which produces oil or gas without any means of artificial lift....

• Hydraulic pump

  An artificial lift system that is powered by injected fluid (usually water), that powers a pump similar to the rotating pump used in electrical submersible pumps. ...
