Abstract:
1. A method of installing an expandable tubular assembly in a wellbore formed in an earth formation, the tubular assembly including a plurality of expandable tubular elements, the method comprising: installing a first tubular element in the wellbore; installing a second tubular element in the wellbore in a manner that an end part of the second tubular element extends into an end part of the first tubular element thereby forming an overlap portion of the tubular assembly, said overlap portion being positioned in the wellbore such that a radially deformable body is arranged around the overlap portion; and radially expanding the end part of the second tubular element against the end part of the first tubular element in a manner that the end part of the first tubular element becomes radially expanded and said deformable body becomes radially deformed, wherein a body of cement is present between the first tubular element and the wellbore wall, characterized in that the deformable body is a fluidic volume which is pumped between the first tubular element and the wellbore wall before hardening of the cement.
