SHOE FOR EXPANDABLE LINER SYSTEM |
摘要 |
An apparatus to protect the mounting area of casing when subsequently attaching a tubular is disclosed. A sleeve (20) that defines a sealed cavity (28) having a loose incompressible material (30) inside covers the mounting location on the casing. The cementing of the casing takes place through the sleeve. After the cementing, the sleeve is drilled out and the incompressibl e material is removed to the surface with the drill cuttings. A tubular (66) i s inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. At the end of expansion, the run in sho e (84) on the tubular is retrieved.
