Method and apparatus for casing expansion

A mono-diameter wellbore (10) casing. The mono-diameter wellbore (10) casing is formed by plastically deforming and radially expanding a first tubular member (155) within a wellbore (10). A second tubular member is then plastically deformed and radially expanded in overlapping relation to the first...

Zusammenfassung:	A mono-diameter wellbore (10) casing. The mono-diameter wellbore (10) casing is formed by plastically deforming and radially expanding a first tubular member (155) within a wellbore (10). A second tubular member is then plastically deformed and radially expanded in overlapping relation to the first tubular member (155). The second tubular member and the overlapping portion of the first tubular member (155) are then radially expanded again.
