Abstract
The invention describes a method of lining a well using expandable tubing including the steps of lowering a expandable tubing in a well bore; injecting a sealant composition into said well; letting the sealant composition solidify into a deformable matrix embedding at least a bottom section of said tubing within said well; and expanding the tubing. The invention allows the creation of a high quality seal at the shoe of the expandable casing because the deformable material is highly stressed by the expansion, and it also allows for the rest of the casing to be properly supported and protected by conventional cement, without incurring excessive wait-on-cement times.
