Zusammenfassung:A method of installing a tubular assembly in a wellbore formed in an earth formation is disclosed whereby the tubular assembly includes a plurality of expandable tubular elements. The method comprises installing a first tubular element in the wellbore, and 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. The end part of the second tubular element is radially expanded 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.
