摘要： 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 before the gas is injected into a subterranean formation. The stream is passed through an upstream separator to separate out the particulates which pass through a first and second set of slots into first and second passages, both of which empty into a bypass through the turbine whereby the separated particulates do not contact the rotary vanes of the turbine thereby alleviating the erosive effects of the solids in the produced stream.

摘要： A method and system for producing a mixed gas-oil stream through a tubing wherein at least a portion of the gas is separated from the stream and flowed through a restriction in the tubing to cool the separated gas and reduce its pressure to thereby retain larger amounts of liquid (i.e. condensate) in the gas-oil stream which is to be produced to the surface. The separated gas is compressed downhole before it is injected into a downhole formation.

摘要： A method and system for producing a mixed gas-oil stream through a wellbore wherein at least a portion of the gas is separated from the stream downhole and is compressed (e.g. using a SPARC) before both the compressed gas and the remainder of the stream is brought to the surface through separate flowpaths. The system includes a string of tubing which provides the flowpath for the remainder of the stream while the annulus, formed between the tubing string and the wellbore provides the flowpath for the compressed gas.

摘要： A system (SPARC) for producing a mixed gas-oil stream wherein gas is to be separated and compressed downhole in a turbine-driven compressor before the gas is injected into a subterranean formation. A turbine bypass valve allows all of the stream to bypass the turbine during start-up until surging in the production stream has subsided. The valve then opens to allow a portion of the stream to pass through the turbine. Also, a compressor recycle valve recycles the compressor output until the surging in the stream has subsided while a check valve prevents back flow into the outlet of the compressor.
