ASSEMBLY AND METHOD FOR CREATING AN EXPANDED TUBULAR ELEMENT IN A BOREHOLE

摘要

An assembly for supporting an expandable tubular element (1) during descend in a borehole comprises an expansion string (2) with support means (16) protruding from an outer surface of the expansion string (2) below an internal upset (48) at the inner surface of a starter section (42) at the lower end of the unexpanded tubular element (1) so as to transmit at least a portion of the weight of the unexpanded tubular element (1) via the internal upset (48) and the support means (16) to the expansion string (2) during descend in the borehole.
