Abstract
A reclosable multi-zone isolation tool including a mandrel assembly with a pull-force lock feature. The tool includes 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 moveable between an open and closed position. A mandrel assembly is slidingly positioned within the inner tubular and coupled to the sleeve to actuate the sleeve between the open and closed position only when a push force is applied. If a pull force is applied, the mandrel assembly 'locks out,' thereby preventing movement of the sleeve.
