Abstract:
A method and apparatus for completing a well through expansion of tubing enable construction of the well or at least part of the well with a mono-diameter or substantially no inside diameter reduction with subsequent casings/liners. Prior to lining an extended section of the borehole, forming a discrete enlarged portion of the extended section with a relatively larger inner diameter than the remainder of the extended section of the borehole occurs where overlapping tubing sections are to be located. For some embodiments, an open-hole clad expanded in the enlarged portion of the extended section of the borehole provides an inner surface for receiving a bottom of a first expanded liner and optionally a top of a second expanded liner.
