Abstract
A gas recovery system where a submersible compressor is in combination with a hydraulic motor. The hydraulic motor is actuated by a pressure differential between hydraulic power lines extending between the motor and a pressure generation means at or near the surface. Hydraulic fluid serves to actuate device components and regulate the temperature of the down hole compressor. A monitoring system evaluates, communicates, and records operation parameters so that they may be adjusted to ensure a constant volume of produced gas. The device may operate at variable speeds to accommodate changing downhole pressure conditions.
Claims5
A gas recovery system comprising:
- a power fluid circulation means, said power fluid circulation means configured for imparting variable pressure and flow to power fluid;
- an elongate conduit means having a first end and a second end, said elongate conduit means being in substantially sealed fluid communication with said fluid circulation means at said first end;
- a fluid activated driving means, said driving means being in substantially sealed fluid communication with said elongate conduit means at said second end;
- a gas compressing means, said gas compressing means being mechanically engaged with said driving means, said compressing means being configured for placement in fluid communication with a subterranean gas source for conveyance of gas from said subterranean gas source substantially to a surface elevation.
A method for recovering gas from a subterranean source comprising the steps of:
- selecting a gas recovery system comprising:
- a power fluid circulation means, said power fluid circulation means configured for imparting variable pressure and flow to power fluid;
- an elongate conduit means having a first end and a second end, said elongate conduit means being in substantially sealed fluid communication with said fluid circulation means at said first end;
- a fluid activated driving means, said driving means being in substantially sealed fluid communication with said elongate conduit means at said second end;
- a gas compressing means, said gas compressing means being mechanically engaged with said driving means, said compressing means being configured for placement in fluid communication with a subterranean gas source for conveyance of gas from said subterranean gas source substantially to a surface elevation.
- positioning said gas recovery system to effectively recover said gas;
- and
- initiating operation of said fluid compressing -system.
