Gas Lift System

A gas lift system consists of compressed gas being injected through gas lift mandrels and valves into the production string. The injected gas lowers the hydrostatic pressure in the production string to establish the required pressure differential between the reservoir and wellbore, and causing the formation fluids to flow to the surface.

Benefits of Gaslift systems include
  • High degree of flexibility and design rates
  • Excellent sand handling capability
  • Minimal amount of surface requirements
  • Minimal moving parts
  • Full bore drift of tubing
  • Wireline retrievable
Applications of Gaslift systems include
  • Wells with insufficient bottomhole pressures or
  • Deep wells with large hydrostatic head and unable to flow by itself
  • Readily available high pressure injection gas near well
  • Kick off wells for natural flow by clearing the heavier completion fluids from tubing
  • Unload water from gas wells that would otherwise prevent gas production
  • Continuous or intermittent flow
Typical Specification
  • Production – Up to 10,000 bpd
  • Depth – From 5,000- 10,000 ft
  • Temperature – Up to 125 degC
  • Wellbore deviation – Up to 50 deg
