Method and apparatus for forming a mono-diameter wellbore casing
A mono-diameter wellbore casing. The mono-diameter wellbore casing is formed by plastically deforming and radially expanding a first tubular member within a wellbore. A second tubular member is then plastically deformed and radially expanded in overlapping relation to the first tubular member. The second tubular member and the overlapping portion of the first tubular member are then radially expanded again.
1. A method of constructing a wellbore casing structure within a wellbore using a plurality of overlapping wellbore casings, comprising:
determining a desired collapse strength for the wellbore casing structure;
determining a required number of overlapping wellbore casings required to provide the desired collapse strength in the wellbore casing structure; and
radially expanding and plastically deforming the required number of wellbore casings onto one another in overlapping fashion within the wellbore.
