Patent ID: 8678097

Claim:
A system for circumferentially aligning a downhole latch subsystem in a wellbore, the system comprising: a casing string positionable in the wellbore; a latch coupling interconnected in the casing string, the latch coupling having a latch profile; a slot subassembly interconnected in the casing string, the slot subassembly having an axially extending slot profile; a tool string positionable within the casing string; a latch assembly interconnected in the tool string, the latch assembly having a plurality of latch keys; and an orienting subassembly interconnected in the tool string, the orienting subassembly having a plurality orienting keys distributed axially in a longitudinal direction of the orienting subassembly, wherein, after axial alignment of the orienting subassembly with the slot subassembly, rotation of the orienting subassembly causes operable engagement of at least one orienting key with the slot profile and, thereafter, axial alignment of the latch assembly with the latch coupling causes operable engagement of the latch keys with the latch profile.
