WINDOW JOINT FOR LATERAL WELLBORE CONSTRUCTION AND METHOD FOR OPENING SAME |
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). |
