Abstract
A wellbore system includes an upper body, a lower body, removably coupled to the upper body, and a passage extending through both the upper body and the lower body, the passage being aligned and extending through an interface between the upper body and the lower body. The wellbore system also includes a latch piston, confined to the lower body, the latch piston being moveable responsive to an applied pressure via the passage. The wellbore system further includes a latch piston retaining ring, confined to the lower body.
Claims17
A wellbore system, comprising:
- an upper body;
- a lower body, removably coupled to the upper body;
- a passage extending through both the upper body and the lower body, the passage being aligned and extending through an interface between the upper body and the lower body;
- a second lower body, different from the lower body, the second lower body being removably coupled to the upper body via one or more fasteners, the second lower body having a passage portion configured to align with a portion of the passage extending through the upper body;
- a latch piston, confined to the lower body, the latch piston being moveable responsive to an applied pressure via the passage, the latch piston moving relative to both the upper body and the lower body;
- and
- a latch piston retaining ring, confined to the lower body.
A wellbore tool kit, comprising:
- an upper body having a first passage extending from a first end to second end;
- a lower body having a second passage extending axially from a top end to a piston chamber, the lower body further comprising:
- one or more gripping components, the gripping component being movable, relative to both the upper body and the lower body, responsive to a pressure applied via the first passage and the second passage;
- and
- one or more gripping component retainers;
- a second lower body having a third passage extending axially from a second top end to a second piston chamber, the second lower body being removably coupled to the upper body via one or more fasteners, wherein the third passage aligns with the first passage when the second lower body is coupled to the upper body;
- wherein the upper body is removably coupled to the lower body such that an interface is formed between the second end and the top end, the first passage and the second passage being aligned when the upper body is coupled to the lower body.
A wellbore system, comprising:
- an upper body;
- a first lower body, configured to removably couple to the upper body;
- a second lower body, different from the first lower body, configured to removably couple to the upper body in place of the first lower body;
- a passage extending through the upper body and through at least one of:
- the first lower body when the first lower body is coupled to the upper body;
- or
- the second lower body when the second lower body is coupled to the upper body;
- wherein the passage extends through an interface between the upper body and at least one of the first lower body or the second lower body;
- a latch piston, confined to at least one of the first lower body or the second lower body, the latch piston being moveable responsive to an applied pressure via the passage, the latch piston moving relative to the upper body and relative to at least one of the first lower body or the second lower body;
- and
- a latch piston retaining ring, confined to at least one of the first lower body or the second lower body.
