ABSTRACT:
An actuator for operating downhole tools includes a tool body and one or more members configured to perform a wellbore task. The tool may include a sealed power and a driven section in pressure communication with the wellbore. A magnetic coupling magnetically connects the power section to the driven section. The power section may include an electric motor; and the driven section may include a speed reducer/torque increaser. In some embodiments, the member may be a positioning member. The positioning member may be manipulated to position a sensor that is configured to measure a parameter of interest. In other embodiments, the member may be an element such as cutting elements that cut wellbore tubulars. In aspects, a method for actuating or operating downhole tools includes using an actuator that utilizes a magnetic coupling to convey energy across a pressure boundary.
