Abstract
A downhole gas compression system is adapted for location in a bore of a natural gas-producing well (10), the system comprising an axial flow compressor (32) and a gas-filled electric drive motor (30). The motor drives the compressor to compress the produced gas, the compressed gas being directed upwardly through production tubing (20) to surface.

A downhole gas compression system adapted for location in a drilled bore extending from surface to intersect a gas-producing formation, the system comprising an axial flow compressor operatively associated with a gas-filled electric drive motor, the compressor and motor being connectable to production tubing and locatable within bore-lining casing.
A downhole gas compression system for location in a bore, the system comprising an axial flow compressor and a gas-filled permanent magnet electric drive motor.
A method of compressing produced gas in a drilled bore extending from surface to intersect a gas-producing formation, utilizing a compressor driven by a gas-filled electric motor, the compressor and motor being connected to production tubing and located within bore-lining casing.
A downhole gas compression system comprising an axial flow, gas lubricated, liquid free compressor directly driven by a gas filled, gas cooled, gas lubricated, liquid free, variable speed, permanent magnet electric drive motor.
A method of compressing gas in a bore for transporting the gas to surface, the method comprising:
- passing produced gas through a downhole, axial flow, gas lubricated, liquid free compressor;
- and directly driving the compressor with a downhole, gas filled, gas cooled, gas lubricated, liquid free, variable speed, permanent magnet electric drive motor.
