摘要： A system for circumferentially aligning a downhole latch subsystem in a wellbore. The system includes an outer tool assembly including a latch coupling (108) having a latch profile (110) and a slot subassembly (112) having an axially extending slot profile (114). An inner tool assembly is positionable within the outer tool assembly. The inner tool assembly includes a latch assembly (122) having a plurality of latch keys (124) and an orienting subassembly (126) having a plurality orienting keys (128). In operation, after axial alignment of the orienting subassembly (126) with the slot subassembly (112), rotation of the orienting subassembly (126) causes operable engagement of at least one orienting key (128) with the slot profile (114) and, thereafter, axial alignment of the latch assembly (122) with the latch coupling causes operable engagement of the latch keys (124) with the latch profile (110).

摘要： An apparatus for circumferentially orienting a downhole latch assembly in a wellbore. The downhole latch assembly has a plurality of latch keys including a primary latch key. The apparatus includes a casing string positionable in the wellbore. A window joint is interconnected in the casing string. A latch coupling having a latch profile is interconnected in the casing string downhole of the window joint. An orienting subassembly interconnected in the casing string has an orienting profile positioned uphole of the latch profile such that, after operable engagement of the primary latch key with the orienting profile, axial alignment of the latch assembly with the latch coupling causes operable engagement of the latch keys with the latch profile.

摘要： A system for opening a window (320) in lateral wellbore construction. The system includes a window joint (300) that is operable to be interconnected within a casing string. The window joint (300) has a window (304) formed therein that is defined by at least one score line (306) that creates a preferentially weaken region within the window joint (300) enabling internal removal of the window (304) in a predictable manner without generating wellbore debris. A window removal tool (310) is operable to be run in the casing string. The window removal tool (310) is operably engagable with the window (304) such that actuation of the window removal tool (310) internally removes the window (304) from the window joint (300), thereby opening the window (320).
