  • UNDERCURED STATOR FOR MUD MOTOR
    Publication number: 20210189848
    Abstract: A stator for a mud motor and methods for manufacturing and using the same, of which one such method includes obtaining a mud motor having a stator made at least partially from a rubber. At least a portion of the rubber is cured by at most about 90%. The method also includes deploying the mud motor into a well as part of a drill string. The rubber is not further cured prior to deploying the mud motor into the well. The method further includes generating torque using the mud motor by pumping a mud through the stator.

  • FLUID PRESSURE ACTUATOR
    Publication number: 20130213032
    Abstract: An actuator including an actuation member at least partially defining a chamber and a fluid generating media disposed in the chamber. The fluid generating media includes a first electrochemical composition and a second electrochemical composition. The first and second electrochemical compositions are together electrochemically responsive to a first fluid for generating a second fluid. The actuation member is actuatable via a pressure of the second fluid. A method of controlling an actuator is also included.
