When Western Falcon of Houston, Texas, USA, a major manufacturer of tubular linings for downhole applications, wanted to design a new high-performance seamless thermoplastic liner, it chose VICTREX® PEEK™ polymer because of its unique combination of tensile strength, chemical resistance, ductility, temperature capabilities and resilience. The new liner, called Extremetube*, offers optimal resistance to damage from artificial lift rod wear, wireline and slickline, coiled tubing, and other common downhole tools.
