Abstract:
1. A running tool, comprising: a cam portion comprising one or more cam structures tapered in an axial direction relative to a downhole configuration of the running tool and tapered in a circumferential direction such that the thickness of each cam structure increases in a circumferential plane of the running tool; a shoe portion tapered in a complementary axial direction relative to the one or more cam structures, wherein the taper of the shoe portion allows the shoe portion to rest on the one or more tapered cam structures in the absence of an externally applied torque; a mandrel comprising a casing running tool portion about which the cam portion and the shoe portion are radially disposed, wherein the mandrel, when rotated in a first direction, engages the cam portion of the running tool and causes the one or more cam structures to push outward on all or part of the shoe portion; and a drive configured to cause rotation of the mandrel in at least the first direction.
