Patent ID: 7552776

Claim:
A method of coupling a tubular member to an existing tubular member in a borehole located in a subterranean formation comprising: installing a tubular liner and an expansion device in the borehole; overlapping the tubular liner with an existing tubular member; injecting fluidic material into the borehole; pressurizing a portion of an interior region of the tubular liner; radially expanding at least a portion of the liner in the borehole by extruding at least a portion of the liner off of the expansion device and into engagement with the existing tubular member; wherein the tubular member comprises: a first tubular section comprising a first outer diameter; an intermediate tubular section coupled to the first tubular section comprising an intermediate outer diameter; and a second tubular section comprising a second outer diameter coupled to the intermediate tubular section comprising a second outer diameter; wherein the first and second outer diameters are greater than the intermediate outer diameter; and wherein an outer surface of the intermediate tubular section comprises a sealing member comprising a first annular layer comprising an elastomer coupled to the outside surface of the intermediate tubular section and a second annular layer comprising a metal coupled to the outside surface of the first annular layer.
