MONO DIAMETER WELLBORE CASING

摘要

An apparatus (120) and system for radially expanding and plastically deformi ng an expandable tubular member (110) where the system comprises an anchoring mechanism (148) adapted to mate with an end of the expandable tubular member (110), a tubular member (125) releasable coupled to the anchoring mechanism (148) /, an adjustable expansion mandrel (140), and an actuator (134) couple d to the adjustable expansion mandrel (140) to controllably longitudinally displace the adjustable expansion mandrel (140) relative to the expandable tubular member (110). The expansion mandrel (140) is controllably expanded t o a larger diameter for radial expansion of the expandable tubular mandrel (11 0) or collapsed to a smaller outside diameter.
