Abstract: An assembly of a setting tool in combination with a delivery tool for an adaptive support allows delivery of the adaptive support in a condition where it stores potential energy. Relative movement between a mandrel and a surrounding sleeve allows release of the adaptive support at a desired subterranean location. The relative movement to release the adaptive support comes from a setting tool that has a setting sleeve and a supporting connection to the mandrel of the delivery tool. The setting sleeve, when triggered to move by preferably an explosive charge, engages a piston rod assembly supported by the delivery tool mandrel for tandem movement to a mandrel travel stop. The tandem movement is regulated, preferably in the delivery tool, with regulation of fluid flow through a restriction to eliminate component failure due to high impact loads when the travel stop is engaged.

Abstract: Seal elements for establishing fluid seals in a wellbore may be constructed of expandable metal materials. For example, an elongated gland of expandable metal may replace some or all the components in a packing stack of a locking mandrel. The gland may be recessed within the locking mandrel, or narrower than a seal bore of a landing nipple, such that the gland is protected from damage as the locking mandrel passes through landing nipples to reach a target landing nipple. The expandable metal may be induced to chemically react with a brine or other water-based fluid to form metal hydroxides and may thus create a seal with the target landing nipple. Once an intended purpose of the locking mandrel has been achieved, a pressure reversal may be employed to break the seal and/or a mild acid may be introduced to accelerate dissolving of the expandable metal seal.
