MONO-DIAMETER WELLBORE CASING

摘要

A method and system for creating a mono-diameter wellbore casing, whereby a tubular liner (210) is radially expanded into contact with a tubular casing (115) by a method of pressurizing a portion of the tubular liner (210) below a first expansion cone (805) and extruding the liner off the first expansion cone (805). The overlap between the liner and casing is then expanded and the portion of the tubular that does not overlap the casing is expanded using a second expansion cone.
