Abstract

A flow transported obturating tool for actuating a valve in a wellbore includes a housing including a first engagement member and a second engagement member, wherein the first and second engagement members each include an unlocked and a locked position, and a core disposed in the housing, wherein the core is configured to actuate both the first engagement member and the second engagement member between the unlocked and locked positions, wherein, when the first engagement member is in the locked position, the first engagement member is configured to locate the obturating tool at a predetermined axial position in the valve, wherein, when the second engagement member is in the locked position, the second engagement member is configured to shift the valve from an open position to a closed position.
