Rotating Hanger System with Ratchet Mechanism

A system for use in a well, comprising:

• a casing hanger;
• a running tool releasably coupled with the casing hanger to enable deployment and rotation of the casing hanger in a borehole;
• and
• a ratchet mechanism positioned between the running tool and the casing hanger, the ratchet mechanism having a lower cam releasably engaged with the casing hanger, the lower cam having a lower cam profile which causes engagement with and rotation of the casing hanger when the running tool is rotated in a first direction and which causes the ratchet mechanism to release from the casing hanger when the running tool is rotated in a second direction, the ratchet mechanism further having an upper cam engaged with the running tool, the upper cam having an upper cam profile which forces the ratchet mechanism toward the casing hanger when the running tool is rotated in the first direction, wherein the running tool comprises an inner portion having a running tool cam profile oriented for engagement with the upper cam profile of the ratchet mechanism, the running tool further comprising an outer portion threadably engaged with the casing hanger along an exterior of the casing hanger.

A system, comprising:

• a casing hanger;
• a running tool having an inner tubular portion and an outer tubular portion rotatably coupled with the casing hanger along an exterior of the casing hanger;
• and
• a ratchet mechanism to facilitate both rotation of the casing hanger by the running tool and release of the running tool from the casing hanger, the ratchet mechanism being sized to fit within the outer tubular portion, the ratchet mechanism comprising:
• a central body portion;
• a lower cam extending from the central body portion and having a lower cam profile which causes engagement with and rotation of the casing hanger when the running tool is rotated in a first direction and which causes the ratchet mechanism to release from the casing hanger when the running tool is rotated in a second direction;
• and
• an upper cam extending from the central body portion opposite the lower cam and having an upper cam profile which forces the ratchet mechanism toward the casing hanger when the running tool is rotated in the first direction, wherein the inner tubular having a running tool cam profile is oriented for engagement with the upper cam profile.

A method, comprising:

• positioning a ratchet mechanism between an inner portion of a running tool and a casing hanger and within an outer portion of the running tool;
• rotatably coupling the running tool to the casing hanger along an exterior of the casing hanger via the outer portion;
• conveying the casing hanger downhole into a borehole via the running tool;
• using a first cam profile of the ratchet mechanism to drive a second cam profile of the ratchet mechanism into secure engagement with the casing hanger by rotating the running tool in a first direction, wherein the inner portion having a running tool cam profile is oriented for engagement with the first cam profile;
• and
• rotating the casing hanger in the borehole in the first direction.
