  • Patent number: 10145196
    Abstract: A mud motor for use in a wellbore includes: a stator; a rotor, the stator and rotor operable to rotate the rotor in response to fluid pumped between the rotor and the stator; and a lock. The lock is operable to: rotationally couple the rotor to the stator in a locked position, receive an instruction signal from the surface, release the rotor in an unlocked position, and actuate from the locked position to the unlocked position in response to receiving the instruction signal.

  • Patent number: 7594540
    Abstract: A method and apparatus for connecting threaded members while ensuring that a proper connection is made. In one embodiment, the applied torque and/or rotation are measured at regular intervals throughout a pipe connection makeup. When a shoulder contact is detected, a predetermined torque value and/or rotation value is added to the measured torque and/or rotation values, respectively, at shoulder contact and rotation continued until this calculated value(s) is reached.

  • Patent number: 7264050
    Abstract: The present invention generally provides a method for remotely controlling and/or monitoring at least one parameter of well bore equipment. In one aspect, a method for remotely controlling and/or monitoring at least one parameter of well bore equipment is provided, including: collecting data corresponding to the at least one parameter by a sensor module monitoring the at least one parameter of the well bore equipment; transmitting the collected data to a remote control/monitoring unit via a communication link; analyzing the collected data to determine if the parameter is within predefined limits; if the parameter is not within predefined limits, then transmitting control data from the control/monitoring unit to the well bore equipment for modifying the operation of the well operation equipment so that the parameter will conform to the predefined limits or stopping operation of the wellbore equipment.

  • Patent number: 6896055
    Abstract: The present invention generally provides a method for remotely controlling and/or monitoring at least one parameter of well bore equipment. In one aspect, the invention includes a method comprising the steps collecting data corresponding to the parameter with a sensor module; transmitting the collected data to an on-site universal data acquisition and control system; transmitting the data from the universal data acquisition and control system to a remote control/monitoring unit via a communication link; and transmitting control data from the control/monitoring unit back to at least the universal data acquisition and control system for modifying the operation of the well operation equipment.
