Abstract
Apparatus and method for anchoring a morphable tubular in a wellbore in which an anchoring system is arranged around the circumference of an expandable portion of the tubular member. The anchoring system has a gripper element with oppositely arranged inclined surfaces and wedge elements having inclined surfaces mutually arranged on either side of the gripper element with at least one of the wedge elements being a beam spring. Following morphing of the tubular member the anchoring system is configured to maintain the gripper element in a radially extended position by action of the at least one beam spring and thereby increase the load bearing capacity of the morphed tubular member in the wellbore.
