Patent Number Title Of Patent Date Issued
6672387 Oil and gas production with downhole separation and reinjection of gas January 6, 2004
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 unti
6564865 Oil and gas production with downhole separation and reinjection of gas May 20, 2003
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
6283204 Oil and gas production with downhole separation and reinjection of gas September 4, 2001
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 a first separator to separate out
6260619 Oil and gas production with downhole separation and compression of gas July 17, 2001
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.
6189614 Oil and gas production with downhole separation and compression of gas February 20, 2001
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
6056054 Method and system for separating and injecting water in a wellbore May 2, 2000
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
6035934 Method and system for separating and injecting gas in a wellbore March 14, 2000
A method and system for increasing oil production from an oil well producing a mixture of oil and gas through a wellbore penetrating an oil-bearing formation containing an oil-bearing zone and a selected injection zone, by driving a turbine in the oil well with the mixture of oil and
6032737 Method and system for increasing oil production from an oil well producing a mixture of oil and March 7, 2000
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
6026901 Method and system for separating and injecting gas in a wellbore February 22, 2000
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,
5988275 Method and system for separating and injecting gas and water in a wellbore November 23, 1999
A method and system for increasing oil production from an oil well producing a mixture of oil, water, and gas through a wellbore penetrating an oil-bearing formation containing an oil-bearing zone, an aqueous zone, and a gas zone by separating from the mixture of oil, water, and gas in
