  • Downhole force generator and method
    Patent number: 6199628
    Abstract: A downhole force generator includes a longitudinal force generating and transmitting assembly (including, for example, a motor and a threaded shaft that is extended and retracted by operation of the motor) adapted to be moved into a well. A controller is also adapted to be moved into the well and is connected to the longitudinal force generating and transmitting assembly. The controller includes a memory containing a program to control the longitudinal force generating and transmitting assembly to obtain at least one desired operating condition in the well. A sensor can be connected to the controller. A self-contained power source adapted to be moved into the well can also be used. A method of providing an infinitely variable linear force in an oil or gas well is a particular application for such a downhole force generator. This particular method comprises sensing in the well a parameter responsive over a continuum to changes in a selected operating condition in the well.
