Abstract
In some implementations, an apparatus may comprise a collet sleeve configured for insertion into a cavity of a mule shoe and including teeth configured to ratchet with pawls of the mule shoe. The apparatus also may comprise a packing element surrounding a portion of the collet sleeve and configured to radially expand to form a seal with a casing of a wellbore in response to a setting force to join the teeth and the pawls.
Claims15
An apparatus comprising:
- a collet sleeve configured for insertion into a cavity of a mule shoe, wherein the collet sleeve includes a plurality of collet fingers extending from a first end of the collet sleeve, each collet finger including teeth configured to ratchet with pawls of the mule shoe;
- a packing element surrounding a portion of the collet sleeve separate from the collet fingers, the packing element configured to radially expand to form a seal with a casing of a wellbore in response to a setting force;
- and
- an element support ring coupled with the collet sleeve and configured to transfer the setting force into the packing element,
- wherein the collet sleeve further includes a flange on a second end, the flange configured to connect the collet sleeve to the element support ring,
- wherein the flange is positioned and supported directly radially within the element support ring, and
- wherein the setting force causes the collet fingers to bend sufficient to ratchet the teeth into the pawls of the mule shoe, locking the collet sleeve into the mule shoe.

A system comprising:
- a mule shoe including-a cavity formed by an inner surface of the mule shoe;
- and
- a plurality of pawls residing on at least a portion of the inner surface of the mule shoe;
- a plug configured to couple with the mule shoe, the plug including:
- a collet sleeve configured for insertion into the cavity, wherein the collet sleeve includes a plurality of collet fingers extending from a first end of the collet sleeve, each collet finger including teeth configured to ratchet with the pawls of the mule shoe;
- a packing element surrounding a portion of the collet sleeve separate from the collet fingers, the packing element configured to radially expand to form a seal with a casing of a wellbore in response to a setting force;
- an element support ring coupled with the collet sleeve and configured to transfer the setting force into the packing element,
- wherein the collet sleeve further includes a flange on a second end, the flange configured to connect the collet sleeve to the element support ring,
- wherein the flange is positioned and supported directly radially within the element support ring, and
- wherein the setting force causes the collet fingers to bend sufficient to ratchet the teeth into the pawls of the mule shoe, locking the collet sleeve into the mule shoe.

A method comprising:
- coupling a wireline adapter kit with a plug assembly, wherein the plug assembly includes:
- a mule shoe including a plurality of pawls;
- and
- a plug, the plug including:
- a collet sleeve that includes a plurality of collet fingers extending from a first end of the collet sleeve, each collet finger including a plurality of teeth;
- a packing element surrounding a portion of the collet sleeve separate from the plurality of collet fingers;
- and
- an element support ring coupled with the collet sleeve and configured to transfer the setting force into the packing element, wherein the collet sleeve further includes a flange on a second end, the flange configured to connect the collet sleeve to the element support ring,
- wherein the flange is positioned and supported directly radially within the element support ring,
- moving the wireline adapter kit and the plug assembly to a location in a wellbore;
- and
- applying, via the wireline adapter kit, a setting force to the plug assembly, the setting force causing the teeth of the collet sleeve to ratchet into the pawls of the mule shoe, locking the collet sleeve into the mule shoe, and further causing the packing element to radially expand to create a seal with a casing of the wellbore.
