More Information
Summary:An apparatus to protect the mounting area (202) of casing and a locating profile (209) and optionally a sliding sleeve valve (200) and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner (218) is intended and the expanded liner is to be cemented in place. A barrier sleeve (204) , nose (207) , and outer sleeve (210) define a sealed cavity having a loose incompressible material (208) inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings.
