  • Remote pressure readout while deploying and undeploying coiled tubing and other well tools
    Patent number: 9644472
    Abstract: A well tool has a pressure sensor disposed in an interior space. The pressure sensor has at least one sensing element estimating a pressure parameter of a fluid in the interior space and a transponder configured to transmit radio frequency (RF) signals representative of the estimated pressure parameter. A data retrieval module receives the RF signals transmitted by the transmitter.
    Type: Grant
    Filed: January 21, 2014
    Date of Patent: May 9, 2017
    Assignee: BAKER HUGHES INCORPORATED
    Inventors: Karsten Fuhst, Jan C. Bertke, Andreas Peter

  • Wellbore tools with non-hydrocarbon-based greases and methods of making such wellbore tools
    Patent number: 9057228
    Abstract: A wellbore tool includes a non-hydrocarbon-based grease disposed between a first component and a second component. The grease remains substantially impermeable to hydrocarbons at temperatures up to at least about 150° C. and possibly up to at least about 200° C., and pressures up to at least about 27 MPa and possibly to at least about 50 MPa. Methods of forming such wellbore tools include selecting a grease to comprise a non-hydrocarbon-based grease that remains at least substantially impermeable to hydrocarbons at temperatures up to at least about 150° C. and possibly up to at least about 200° C., and pressures up to at least about 27 MPa and possibly to at least about 50 MPa; and disposing the grease at an interface between a first component of a wellbore tool and a second component of a wellbore tool.
