  • Turbine drilling assembly with near drilling bit sensors
    Patent number: 10273800
    Abstract: A turbine drilling assembly can include a turbine drilling motor having an upper drill string connector, and an inclination sensor positioned in the turbine drilling assembly below the upper drill string connector. Another turbine drilling assembly can include a turbine drilling motor having an upper drill string connector, a sensor positioned in the turbine drilling assembly below the upper drill string connector, and a transmitter which transmits sensor data through a housing of the turbine drilling motor.
    Type: Grant

  • Drilling motor with one-way rotary clutch
    Patent number: 9777540
    Abstract: A drilling motor assembly can include a housing, a shaft, and a pawl which selectively engages a recess, the pawl having an axis of rotation and a generally planar engagement face which engages a generally planar engagement face of the recess when relative rotation between the housing and the shaft is prevented. The engaged engagement faces can be oblique relative to a radius extending from the axis of rotation to the engaged engagement faces. A method of drilling a wellbore can include flowing a fluid through a drilling motor assembly, thereby rotating a shaft relative to a housing, and rotating the housing, thereby engaging a pawl with a recess and preventing relative rotation between the housing and the shaft, the pawl and recess each having a generally planar engagement face, whereby the engaged engagement faces prevent relative rotation between the shaft and the housing.
