Gas lift mandrel

A gas lift mandrel configured to be operably coupled to a well tubing wherein the gas lift mandrel comprises:

• a body, said body having a wall member, said wall member defining an interior volume, said body having a first end and a second end;
• a gas capillary tube member, said gas capillary tube member having a first end and a second end, said gas capillary tube member being hollow, said gas capillary tube member being operably coupled to a pump proximate said first end of said gas capillary tube member wherein the pump is located on a surface proximate a well, said second end of said capillary tube member terminating within the interior volume of said body;
• a burst disc member, said burst disc member being disposed within said interior volume of said body, said burst disc member being sealably coupled to said second end of said gas capillary tube member, said burst disc member having a membrane operable to rupture ensuing exposure to a determined pressure;
• a valve assembly, said valve assembly further including a sleeve member, said sleeve member configured to be movable between a first position and a second position;
• and
• wherein said sleeve member of said valve assembly is moved to said second position ensuing rupture of said burst disc member resulting in exposure of said valve assembly to pressure from a fluid disposed in said gas capillary tube member.
