Method of forming a high-strength sealed connection for expandable tubulars

A method of forming a sealed tubular joint, said method comprising the steps of:

• providing a first radially expandable tubular member having external male threading and a first free end, the external male threading including a first incomplete thread and a first hooked thread, the first incomplete thread being located at least adjacent the first free end of the first tubular member;
• providing a second radially expandable tubular member having internal female threading and a second free end, the internal female threading including a second incomplete thread and a second hooked thread, the second incomplete thread being located at least adjacent the second free end of the second tubular member;
• coating at least one of the external male threading and the internal female threading with a greaseless elastomeric sealant;
• coupling the first tubular member and the second tubular member, said coupling thereby providing a threaded connection;
• disposing the greaseless elastomeric sealant between the external male threading and the internal female threading and into adherence with each of the external male threading and the internal female threading;
• curing the greaseless elastomeric sealant, said curing thereby providing a cured greaseless elastomeric sealant that is extended between and adhered to the external male threading and the internal female threading and has an elastic modulus less than about 2.0 MPa (290 p.s.i);
• and
• radially expanding the threaded connection, until the cured greaseless elastomeric sealant is thereby elongated at least about 45 percent while remaining extended between and adhered to the external male threading and the internal female threading.
