  • Processing exhaust for use in enhanced oil recovery
    Patent number: 9784140
    Abstract: A method for generating steam for hydrocarbon production is provided. The method includes producing steam using heat from an exhaust stream from a gas turbine system. A water stream is condensed from combustion products in the exhaust stream, and the water stream is used as a make-up water for production of the steam.
    Type: Grant
    Filed: February 24, 2014
    Date of Patent: October 10, 2017
    Assignee: ExxonMobil Upstream Research Company
    Inventors: Richard A. Huntington, Robert D. Denton, Patrick D. McMahon, Lalit K. Bohra, Jasper L. Dickson

  • Low emission power generation and hydrocarbon recovery systems and methods
    Patent number: 8734545
    Abstract: Methods and systems for low emission power generation in hydrocarbon recovery processes are provided. One system includes integrated pressure maintenance and miscible flood systems with low emission power generation. The system may also include integration of a pressure swing reformer (PSR), air-blown auto-thermal reformer (ATR), or oxygen-blown ATR with a gas power turbine system, preferably a combined cycle gas power turbine system. Such systems may be employed to capture and utilize greenhouse gases (GHG) and generate power for use in hydrocarbon recovery operations.
