  • Submersible pumping system
    Patent number: 8196667
    Abstract: A technique is provided for pumping fluids in a subterranean wellbore. A submersible pumping system can be deployed in a wellbore for moving desired fluids within the wellbore. The pumping system energizes the desired fluid movement by reciprocating a working fluid between expandable members.

  • DOWNHOLE OIL-WATER-SOLIDS SEPARATION
    Publication number: 20120006543
    Abstract: A technique facilitates separating fluids and solids and handling the separated solids downhole. A separator system is provided with a separator having a well fluid inlet, an oil stream passage, a water stream passage, and a solids passage. The separator operates to separate well fluid into substantially oil, water, and solids components and those components are directed to the corresponding passages. A flow restrictor may be used in cooperation with the separator to facilitate separation of the well fluid components.
