ABSTRACT:
A method of installing an expandable tubular assembly in a wellbore, the tubular assembly including a plurality of expandable tubular elements, comprising: installing a first tubular element in the wellbore; installing a second tubular element in the wellbore such that an end part of the second tubular element extends into an end part of the first tubular element, arranging a radially deformable body around the overlapping portion; and radially expanding the end part of the second tubular element against the end part of the first tubular element such that the end part of the first tubular element becomes radially expanded and the deformable body becomes radially deformed, wherein a body of cement is present between the first tubular element and the wellbore wall, and wherein the deformable body is a fluidic volume that is pumped between the first tubular element and the wellbore wall before hardening of the cement.
