A gas lift or bubble pump is a type of pump that can raise fluid between elevations by introducing gas bubbles into a vertical outlet tube; as the bubbles rise within the tube they cause a drop in the hydrostatic pressure behind them, causing the fluid to be pulled up.

Gas lift is an artificial lift system where gas is injected into a produced well casing to help lift liquids up to the surface through the production tubing. In this video, Kyle explains why a producer may choose to use gas lift, walks through the two types of gas lift, highlights the components of the system and explains how it operates.

Jul 15, 2015 · Gas lifts use the artificial lift method by injecting gas into the production tubing to raise water or oil. The gas injected is high-pressure gas by adding bubbles of compressed air and vapor. This acts to lower the hydrostatic pressure at the bottom of the tubing, reducing its density.

Jul 29, 2016 · Gas lift systems aid or increase production by injecting high-pressure gas from the casing annulus into fluids that have entered the production tubing from the formation. The injected gas reduces the fluid density and, thus, the hydrostatic pressure of the fluid, allowing in situ reservoir pressure to lift the lightened liquids.

Jan 28, 2025 · Gas lift is a method of artificial lift that uses an external source of high-pressure gas for supplementing formation gas to lift the well fluids. The principle of gas lift is that gas injected into the tubing reduces the density of the fluids in the tubing, and the bubbles have a “scrubbing” action on the liquids.

Gas lift is a field-proven artificial lift method that dates back at least five decades. It relies on external high-pressure gas injected into the wellbore to stimulate and lift produced fluids to the surface for separation and further processing.

Sep 28, 2023 · Gas lift is a method of artificial lift that uses an external source of high-pressure gas to lift well fluids to the surface. It is one of the most common artificial lift methods used in the oil and gas industry, and is particularly well-suited for wells.

Gas lift uses a high-pressure source to inject gas into the production string through a series of valves. As the gas flows to the surface, it expands, reducing the density and column weight of the fluid.

Gas lift is an artificial-lift method for enhancing crude oil recovery from a reservoir. Gas lift systems serve several purposes, such as : Increasing production rates by reducing back pressure in the wellbore. Enhancing oil recovery from reservoirs with high water cut or …

An artificial-lift method in which gas is injected into the production tubing to reduce the hydrostatic pressure of the fluid column. The resulting reduction in bottomhole pressure allows the reservoir liquids to enter the wellbore at a higher flow rate.
