  • Drilling motor with a locking collet sleeve stabilizer
    Patent number: 8770318
    Abstract: A threaded sleeve stabilizer spans an upper stator connection in a mud driven drilling motor used for borehole drilling. A number of collets are loaded in compression between the stator and the housing of the motor, and are held in compression by a threaded connection.

  • Method and apparatus for shifting speeds in a fluid-actuated motor
    Publication number: 20060243493
    Abstract: A method and apparatus for changing the speed of a drill bit down hole in a fluid-actuated motor, including a positive displacement motor and a hydraulic motor, is disclosed. The apparatus comprises a bypass valve installed in the motor for controlling flow through and around the power section of the motor. When closed, the bypass valve forces all fluid to flow through the power section of the motor, imparting maximum speed to the drill bit. When opened, a portion of the fluid flow is allowed to flow around the power section of the motor, thereby reducing the speed of the drill bit. The bypass valve may be opened or closed mechanically, electrically, hydraulically, pneumatically, or by any other means, including a removable plug.
