Abstract

A method of anchoring a morphable tubular in a wellbore includes providing a first tubular member including an expandable portion having an anchoring system arranged around a circumference thereof, the anchoring system including a gripper element, two wedge elements having inclined surfaces oriented to engage two oppositely arranged inclined surfaces of the gripper element, wherein each wedge element includes a beam spring, which are oppositely arranged to act against the inclined surfaces of the gripper element, locating the expandable portion in an existing tubular in a wellbore, introducing fluid pressure to an inner surface of the expandable portion and morphing the expandable portion towards the existing tubing so that the gripper element engages an inner surface of the existing tubing, reducing the fluid pressure, and maintaining engagement of the gripper element on the inner surface by action of the at least one beam spring axially on the gripper element.
