English

Subject field(s)
  • Oil and Natural Gas Extraction
DEF

A method of lifting oil from the bottom of a well to the surface by the use of compressed gas.

CONT

Many oil wells do not have a formation pressure high enough to push the oil ... to the surface. In these cases, some artificial method for lifting the oil to the surface must be installed. [A] method, called gas lift, uses the buoyancy of a bubble of gas in the tubing to push the oil to the surface.

OBS

The gas is pumped into the hole and at the lower end of the tubing it becomes a part of the fluid in the well. As the gas expands, it lifts the oil to the surface.
