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.

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.

2025年1月28日 · 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.

2017年8月4日 · Gas lift systems are a closed system empowered by high-pressured gas. The entire process is used to reduce the wellbore fluid pressure gradient by supplementing gas...

2016年7月29日 · 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.

2017年1月1日 · Gas lift helps the reservoir which is able to drive oil to the well bottom but not to the surface to produce in an economic rate (Mahdiani and Khamehchi 2015b). In this method, gas is injected to the well, dissolves in oil and decreases the head pressure in the well.

2024年5月13日 · Gas lift systems are widely used in the oil industry to enhance production from oil wells by injecting gas into the wellbore to reduce the density of the fluid column, thereby increasing the flow of oil to the surface. Here’s how gas …

2015年7月15日 · What is a Gas lift? 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.

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.

1987年1月1日 · The subsurface gas-lift installations can be divided into three types: (1) fluid discharge occurs up the tubing with gas being injected into the annular space; (2) fluid discharge occurs up the annular space with gas being injected down the tubing; and (3) there are two connected tubings, with gas being injected down one and fluids being lifted ...
