Abstract
An expansion apparatus for expanding a portion of a tubular comprises at least two expansion members adapted for selective deployment against a wall of a tubular. The expansion apparatus may be controlled to select a first expansion member to be deployed and the apparatus operated to expand a section of the tubular. The deployed expansion member may then be inactivated or retracted, such that the expansion member is no longer deployed against the wall of the tubular or is otherwise rendered inoperative, and a second expansion member can then be deployed and a further section of the tubular expanded.
