The use of pumping equipent to lift the fluids out of a well.
A technique used for increasing the productivity of wells with low reservoir pressure and/or heavy fluids (water, heavy oil) and enabling them to flow to surface either by introducing lighter weight fluid (gas) into the stream deep in the well or by providing a downhole pumping system (electrical or hydraulic submersible pumps - ESPs/HSPs).
techniques for producing oil after depletion or in lieu of natural drives; includes waterflooding, natural gas reinjection, inert gas injection, flue gas injection and in-situ combustion.
Any of the techniques, other than natural drives, for bringing oil to the surface.
any method used to raise oil to the surface through a well after reservoir pressure has has declined to the point at which the well no longer produces by means of natural energy. Sucker rod pumps, gas lift, hydraulic pumps, and submersible electric pumps are the most common forms of artificial lift.
Artificial lift system involves the use of artificial means to improve the flow of fluids like crude oil,water and gas to the surface by implementing a mechanical device in or on the wellbore, which can be high pressure gas, mechanical pumps or velocity strings. Artificial lift is needed in wells when there is insuffcient pressure in the reservoir to lift the fluid to the surface. This fluid can be both oil, water and gas.
