Title: METHOD FOR REPAIRING A TUBULAR
Abstract:
A method for lining at least a portion of the inner wall of an upstanding tubular includes inserting a liner sleeve (4) into the tubular (1). The liner sleeve (4) comprises a sleeve of flexible sheet material impregnated with and/or coated with a curable polymer composition. The liner sleeve (4) is held in the tubular (1) and a liner sleeve locating tool (18) is inserted into the tubular and inside the liner sleeve. Operating the liner sleeve locating tool (18) holds the outer surface of the liner sleeve in contact with the inner surface of the tubular (1); and curing the polymer composition bonds the liner sleeve (4) to the inner wall. Alternatively the liner sleeve (4) may be filled with fluid to hold its outer surface in contact with the tubular (1) to allow curing and bonding.
