  • Oil operated rotary steerable system
    Patent number: 9309722
    Abstract: A technique facilitates steering of rotary steerable systems when conducting directional drilling operations. A rotary steerable system is combined with a pressurized oil system which delivers oil to a piston actuated mechanism. The pressurized oil provides precise, long-lasting control over the orientation of the bottom hole assembly and the drill bit to facilitate directional drilling of boreholes through subterranean formations.
    Type: Grant

  • Downhole fluid pumping apparatus and method
    Patent number: 7124819
    Abstract: A downhole fluid pump including a pump chamber, and a piston disposed in the pump chamber so that the piston will move in one selected from a charge stroke and a discharge stroke when the piston is exposed to a differential pressure. The downhole fluid pump may form part of a formation evaluation while drilling tool.
