Title:
OIL AND GAS PRODUCTION WITH DOWNHOLE SEPARATION AND REINJECTION OF GAS
Document Type and Number:
WIPO Patent Application WO2003054112
Kind Code:
A3
Abstract:
A system for producing a mixed gas-oil stream which contains solid particulates wherein gas is to be separated and compressed downhole in a turbine-driven compressor (17) before the gas is injected into a subterranean formation. The stream is passed through an upstream separator (16) to separate out the particulates which pass through a first (26) and second (28) set of slots into first (27) and second (29) passages, both of which empty into a bypass (31) through the turbine (17) whereby the separated particulates do not contact the rotary vanes of the turbine (17) thereby alleviating the erosive effects of the solids in the produced stream.
