Abstract
A method for rotating a casing string in a borehole and a mandrel casing hanger and running tool system, include a selectively engageable connection between a mandrel casing hanger and a running tool; and a rotational force may be applied to the mandrel casing hanger, running tool, and casing string, without substantially tightening a threaded connection between the running tool and the mandrel casing hanger, by transmitting the rotational force through the selectively engageable connection.
