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.

166266, 1661055, 166369, 95261, 95270, 96196, 96216

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.

166265

A method and system for increasing oil production from an oil well producing a mixture of oil, water, gas, and/or solids through a wellbore penetrating an oil-bearing formation containing an oil-bearing zone and a selected injection zone, by separating from the mixture of oil, water, gas, and/or solids in the oil well at least a portion of the gas to produce a first separated gas and a first portion of an oil-enriched mixture; directing the first portion of the oil-enriched mixture through a bypass passageway having an outlet in fluid communication with a surface so that the first portion of the oil-enriched mixture bypasses a turbine in the oil well; driving the turbine with the first separated gas; driving a compressor in the oil well with the turbine; separating from the first separated gas in the oil well at least a portion of the gas to produce a second separated gas and a second portion of an oil-enriched mixture; compressing with the compressor the second separated gas to a pressure greater than a pressure in the selected injection zone to produce a compressed gas; injecting the compressed gas into the selected injection zone; and recovering at least a major portion of the first portion of the oil-enriched mixture and the second portion of the oil-enriched mixture.

A method and system for increasing oil production from an oil well producing a mixture of oil and gas at an elevated pressure through a wellbore penetrating an oil-bearing formation containing an oil-bearing zone and an injection zone, by separating at least a portion of the gas from the mixture of oil and gas to produce a separated gas and an oil-enriched mixture; utilizing energy from at least a portion of the mixture of oil and gas to compress at a surface at least a portion of the separated gas to produce a compressed gas having sufficient pressure to be injected into the injection zone; injecting the compressed gas into the injection zone; and recovering at least a major portion of the oil-enriched mixture.

A method and system for increasing the production of hydrocarbons from a production well producing a mixture of hydrocarbons and water through a wellbore penetrating a formation having a production zone producing a mixture of hydrocarbons and water, and a selected injection zone, by separating, in the wellbore, at least a portion of the water from the mixture of hydrocarbons and water, to produce separated water and a hydrocarbon enriched mixture; injecting, by the use of a pump drivingly connected to a turbine, at least a major portion of the separated water into the selected injection zone; and recovering at least a major portion of the hydrocarbon enriched mixture.

166265

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.

166266

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.
