A mono-diameter wellbore casing is formed by radially expanding a first tubular liner off of a mandrel into contact with a second tubular liner. The first and second tubular liners are positioned within the wellbore in an overlapping relationship. The overlapping portions of the tubular liners include thin wall portions with compressible annular members that are expanded into contact with each other.
