Apparatus for completing a subterranean well and associated methods of using same

摘要

Apparatus and method of forming an opening through a tubular structure in a subterranean well. The apparatus comprises a milling guide (236) having a guide profile (244) formed thereon which is operative to guide a cutting tool (232) to contact the tubular structure. An anchor portion (234) of the milling guide (236) grippingly engages the tubular structure to thereby axially and rotationally align the milling guide with the tubular structure. A hydraulic advance mechanism (228) axially displaces the cutting tool (232) relative to the milling guide (236).
