Abstract:
A reclosable multi-zone isolation tool including a piston assembly with a lock out feature. The tool has an outer and inner tubular having an annular flow path defined there between, and a central flow path defined by the inner tubular. The annular flow path is in fluid communication with the first zone, while the central flow path is in fluid communication with the second zone. A sleeve is positioned in the annular flow path and axially moveable between an open and closed position. A mandrel is positioned within the inner tubular and coupled to the sleeve to actuate the sleeve between the open and closed position. A pressure responsive piston assembly is coupled to the mandrel in order to actuate the sleeve to the open position. Once in the open position, the piston assembly is “locked out,” thereby allowing the mandrel and sleeve to move relative to the piston between the open and closed positions.

Claim (Index 1):
An apparatus for isolating a first zone from a second zone in a subterranean wellbore, the apparatus comprising:\n an outer tubular; an inner tubular positioned within the outer tubular, thereby forming an annular flow path there between that is in fluid communication with the first zone, wherein the inner tubular defines a central flow path therein that is in fluid communication with the second zone; a sleeve positioned in the annular flow path to control fluid flow there through, the sleeve being axially moveable relative to the outer and inner tubular between a closed position and an open position; a mandrel slidingly positioned within the inner tubular and coupled to the sleeve, the mandrel being operable to shift the sleeve between the open and closed position; and a piston assembly positioned around the mandrel, the piston assembly comprising: a piston housing; and\n a piston slidingly positioned within the piston housing and selectively coupled to the mandrel, the piston being operable to receive pressure from within the central flow path and thereby move the sleeve to the open position, \n wherein, once in the open position, the piston is operable to become locked out such that the mandrel is free to move relative to the piston and the sleeve is free to move between the open and closed positions.
