Abstract
An apparatus for use with a device used in a well with a wellhead housing includes a sleeve comprising an interior profile that is configured to be coupled to the wellhead housing and an engagement assembly comprising an exterior profile that is configured to engage with the interior profile of the sleeve to prevent axial movement between the engagement assembly and the sleeve. The apparatus further includes a latch assembly coupled to the engagement assembly and configured to latch to the device.
Claims18
A system for use with a device used in a well, the device including a shoulder and a sleeve comprising a recessed interior profile and the device being located at a fixed location near the surface of or deeper within the well, the system comprising:
- an engagement assembly comprising a protrudable exterior profile that is configured to engage with the recessed interior profile of the sleeve to prevent axial movement between the engagement assembly and the sleeve, the engagement assembly further comprising:
- an outer housing;
- and
- a linear actuator comprising a tapered surface positioned within and moveable relative to the outer housing;
- and
- a latch assembly coupled to and moveable by the operation of the linear actuator and configured to latch to the device;
- wherein engagement by the outer housing with the shoulder prevents further movement of the outer housing, and further movement of the tapered surface of the linear actuator within the outer housing protrudes the protrudable exterior profile into engagement with the recessed interior profile.
A method to latch an engagement assembly to a device used within a well with a wellhead housing at or near the surface of the well, comprising:
- engaging the engagement assembly with a recessed interior profile recessed into an interior surface of a sleeve located within the wellhead housing above a crown plug receptacle to prevent axial movement between the engagement assembly and the sleeve by protruding a key of the engagement assembly out of an outer housing of the engagement assembly and into engagement with the recessed interior profile;
- latching a latch assembly coupled to a linear actuator of the engagement assembly to the device used within the well;
- and
- wherein protruding the key comprises moving a tapered surface of the linear actuator within the outer housing to engage and protrude the key.
A system for use with a device in a well, the device including a shoulder and a sleeve comprising a recessed interior profile and the device being located at a fixed location near the surface of or deeper within the well, the system comprising:
- an engagement assembly comprising:
- an outer housing comprising a bore and a plurality of openings formed through a wall of the outer housing;
- a linear actuator comprising a tapered surface positioned within the outer housing;
- and
- a plurality of keys, each key configured to protrude through one of the openings to engage with the recessed interior profile of the sleeve and prevent axial movement between the engagement assembly and the sleeve;
- wherein engagement by the outer housing with the shoulder prevents further movement of the outer housing, and further movement of the tapered surface within the outer housing protrudes the keys into engagement with the recessed interior profile;
- and
- a latch assembly coupled to and moveable by operation of the linear actuator and configured to extend and retract from an end of the engagement assembly to latch to the device.
