<p>A rotating tool combinable with other downhole tools into a tool string, where the rotating tool is capable of imparting a rotational force onto the tool string. The tool string is suspendable from a threaded lead screw. Optionally, a gyroscope can be included to generate azimuthal readings and confirm the azimuthal orientation of the tool string. The rotating tool includes a compression assembly, a hydraulic assembly, and a stationary assembly. Actuation of a valve on the hydraulic assembly provides for the release of fluid therein that allows for movement of a rotating piston. Rotation of the piston is produced as it travels axially along the threaded lead screw, the rotation of the piston is subsequently transferred to the rotating tool.</p> |
