Abstract

Shearable lift gas valves ('SLG valves') are installed in a well and operate on a contingency basis for injecting lift gas into the well; such as when a lift gas valve that has been in service becomes inoperable or inefficient, or changed well conditions necessitate some form of artificial lift. The SLG valves are maintained in a non-activated configuration with an inner retaining element, and are activated by applying a designated pressure that fractures the retaining element; when activated, the SLG valves operate like other automatic lift gas valves. A SLG valve is installed at a set pressure to replace the inoperable lift gas valve, or at a set pressure that anticipates a change in well conditions, so that when activated, the SLG valve functions at a set pressure different from an in service lift gas valve, and optimizes production from the well with the changed conditions.
