  • Fluid erosion protection washer for rotating shaft in MWD tool
    Patent number: 7839719
    Abstract: A shaft protection washer to protect a rotating shaft in a “measurement while drilling” (MWD) tool. Use of the shaft protection washer renders the rotating shaft less susceptible to erosion from the drilling fluid flowing between the rotating component and the stationary component.
    Type: Grant
    Filed: February 26, 2009
    Date of Patent: November 23, 2010
    Assignee: Schlumberger Technology Corporation
    Inventors: Anthony R. Dopf, Trang Le, Derek Logan, Timothy Neff, Wendall Siemens, Dave Switzer

  • Acoustic telemetry system optimization
    Publication number: 20070257809
    Abstract: A system and method of closed loop control whereby acoustic telemetry devices, both at surface and downhole, form nodes of a feedback loop; said feedback loop enables an automatic and dynamic means to modify transmission parameters such that the system's telemetry data rate is maximized consistent with minimum achievable signal-to-noise ratio and minimum expended power.
