Is the injection of gas through the well annulus down to calibrated gas lift valves to lighten the produced fluid column in the tubing. Used to start up well-flow and enhance flowrates.
The technique of raising a liquid in a vertical flow line by injecting a gas below a portion of the liquid column causing upward flow.
A recovery method that brings oil from the bottom of a well to the surface by using compressed gas. Gas pumped to the bottom of the reservoir mixes with fluid, expands it, and lifts it to the surface.
the process of raising or lifting fluid from a well by injecting gas down the well through tubing or through the tubing-casing annulus. Injected gas aerates the fluid to make it exert less pressure than the formation does; consequently, the higher formation pressure forces the fluid out of the wellbore. Gas may be injected continuously or intermittently, depending on the producing characteristics of the well and the arrangement of the gas-lift equipment.
Gas from same or nearby field is mixed with oil in tubing to lessen weight of liquid column.
The process of raising or lifting fluid from a well by means of gas injected down the well through tubing or tubing casing annulus. Injected gas aerates the fluid to make it exert less pressure than the formation pressure, consequently forcing the fluid out of the wellbore.
Gas lift is one of a number of processes used to artificially lift oil or water from wells where there is insufficient reservoir pressure to produce the well. The process involves injecting gas through the tubing-casing annulus. Injected gas aerates the fluid to make it less dense; the formation pressure is then able to lift the oil column and forces the fluid out of the wellbore.
