    Monobore expandable liner extension system For years, the industry has sought to prove the feasibility of monobore expandable liner extensions as an alternative to conventional casing designs. The goal is to enable the operator to drill deeper exploration and production wells with larger hole sizes at the reservoir. If necessary, the operator can isolate zones that contain reactive shales, subsalt environments, low-fracture-gradient formations or other drilling situations without having to reduce the casing and subsequent drilled hole size into the reservoir. The linEXX Solid Expandable System is a collaborative development between Baker Oil Tools and BP. It was successfully installed in a commercial well in southeast Oklahoma. Deployment included an RC9-R recess shoe run on the 9 5/8-in. parent casing string, FORMlock expandable hanger/packer, 36 joints of 8.0-in. by 0.345-in. wall expandable liner and an RNX guide shoe.
