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 4):
An apparatus as defined in  claim 1 , wherein:\n the piston comprises a shear screw that selectively couples the piston to the mandrel; and the piston housing comprises a snap ring slidingly engaging an outer surface of the piston such that the piston is allowed to move relative to the snap ring in a first direction whereby the sleeve is in the open position, wherein, once in the open position, the snap ring mates with a groove on the outer surface of the piston, whereby the piston is locked out from movement relative to the snap ring in a second direction opposite the first direction.
