  • Patent number: 6164376
    Abstract: The present invention relates to an apparatus and method for selectively lifting produced fluid, including produced hydrocarbons and a portion of produced water, to a ground surface and for multiplying a hydrostatic head of a column of the produced fluid into a magnified injection pressure for injecting, without lifting to the ground surface, the remaining produced water, subsurface, in a subterranean well.
    Type: Grant
    Filed: July 1, 1998
    Date of Patent: December 26, 2000
    Assignee: Texaco Inc.
    Inventors: Lon A. Stuebinger, Howard L. McKinzie

  • Patent number: 6131660
    Abstract: The present invention relates to an apparatus and method for selectively lifting produced fluids, including produced hydrocarbons and a portion of produced water, to a ground surface while injecting the remaining produced water into an injection zone subsurface in a subterranean well. The invention preferably utilizes a rod pump/electrical submersible centrifugal pump to carry out the dual injection and lifting steps. Further, this apparatus and method make it possible to produce hydrocarbons from oil wells in a manner that poses less risk and disturbance to the environment.
    Type: Grant

  • Patent number: 6123149
    Abstract: The present invention relates to an apparatus and method for selectively lifting produced fluids, including produced hydrocarbons and a portion of produced water, to a ground surface while injecting the remaining produced water into an injection zone subsurface in a subterranean well. The invention preferably utilizes an electrical submersible progressive cavity pump (ESPCP) in conjunction with an electrical submersible pump (ESP) in order to carry out the dual injection and lifting steps. Further, this apparatus and method make it possible to produce hydrocarbons from oil wells in a manner that poses less risk and disturbance to the environment.

  • Patent number: 6116341
    Abstract: The present invention relates to an apparatus and a method for multiplying the hydrostatic head of a column of liquid into a magnified injection pressure for injecting water produced in a gas well into a disposal zone, while concurrently producing the gas, with little or no water, to the ground surface.
    Type: Grant

  • Patent number: 6092599
    Abstract: The present invention relates to a downhole oil and water separation system having a casing which includes an interval in communication with a producing zone. The system further includes two pumps disposed in the casing for use in lifting segregated produced hydrocarbons and portion of produced water and segregated produced water to the ground surface.

  • Patent number: 6092600
    Abstract: The present invention relates to an apparatus and method for selectively lifting produced fluids, including produced hydrocarbons and a portion of produced water, to a ground surface while injecting the remaining produced water into an injection zone subsurface in a subterranean well. The invention preferably utilizes a rod-driven progressive cavity pump (RD-PCP) in conjunction with an electrical submersible pump (ESP) in order to carry out the dual injection and lifting steps. Further, this apparatus and method make it possible to produce hydrocarbons from oil wells in a manner that poses less risk and disturbance to the environment.

  • Patent number: 5497832
    Abstract: A system for improving the economics of production by reducing lifting costs of a producing well utilizes the upstroke of a pump to produce a fluid mixture of primarily oil with only a fraction of the produced water and the downstroke to inject the remaining produced water beneath a packer into a lower formation.
