In one aspect, an apparatus for use in a wellbore is disclosed, including an occlusion retaining mechanism; a rupture member associated with the occlusion retaining mechanism; an inertial member configured to puncture the rupture member in response an inertial event to release an occlusion from the occlusion retaining mechanism. In another aspect, a method for isolating a portion of a wellbore is disclosed, including providing a tubular in the wellbore; deploying a perforation gun in the tubular; deploying a frac plug in the wellbore; setting the frac plug in the wellbore; deploying a frac ball release tool associated with the perforation gun; selectively retaining a frac ball within the frac ball release tool; releasing the frac ball in response to an inertial event via an inertial member associated with the frac ball release tool.
