ABSTRACT:
A wellbore operation in which a downhole tool is given rotary motion without rotating the tubing string to which it is attached. A "Yankee screwdriver" type of connecting element is used to connect a downhole tool to a tubing string so that compressive forces acting on the connector as a result of relative linear movement between the connector and the tool cause the tool to rotate. A number of various types of downhole operations are possible, such as rotating a tool away from an obstruction and retrieving the upper section of a lost tubing string.
