Patents by Inventor Bruce E. Weightman

Bruce E. Weightman has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Computer controlled gas lift system
    Patent number: 5937945
    Abstract: Computer control and sensory information are combined with gas lift valve having a plurality of individual openings which are openable or closeable individually to provide varying flow rates of the lift gas. Each of the openings is controlled and is sensitive to downhole sensors.
    Type: Grant
    Filed: August 20, 1998
    Date of Patent: August 17, 1999
    Assignee: Baker Hughes Incorporated
    Inventors: Terry R. Bussear, Bruce E. Weightman
  • Pressure test method for permanent downhole wells and apparatus therefore
    Patent number: 5934371
    Abstract: A permanently installed, remotely monitored and controlled transient pressure test system is provided. This system utilizes shut-in/choke valves, pressure sensors and flow meters which are permanently associated with the completion string to perform transient pressure tests in single and multiple zone production and injection wells. The present invention permits full bore testing which thereby eliminates undesirable wellbore storage effects. The present invention further allows for pressure testing limited only to a selected zone (or zones) in a well without expensive well intervention and without halting production from, or injection into, other zones in the well. The permanently located pressure test system of this invention also allows for real-time, downhole nodal sensitivity and control. This pressure test system may be permanently deployed either in production wells or injection wells.
