Claim 14:
15. A ball-in-place plug configured to isolate formation zones within a wellbore, the ball-in-place plug comprising:
an anchoring subassembly configured to secure the ball-in-place plug in the wellbore; and
a flow control subassembly configured to control the flow of fluid through the plug, wherein the flow control subassembly is configured to allow bidirectional flow of fluid through the ball-in-place plug before the ball-in-place plug is activated, and wherein the flow control subassembly is configured to permit only unidirectional flow of fluid through the ball-in-place plug after the ball-in-place plug is activated, wherein the flow control subassembly comprises:
a central chamber;
a ball; and
an offset chamber connected to the central chamber, wherein the offset chamber includes a ball release mechanism that is configured to selectively release the ball from the offset chamber into the central chamber, wherein the ball release mechanism is configured to rupture in response to a force applied to the ball that exceeds a threshold rupture force of the ball release mechanism, and wherein the threshold rupture force is produced in part by a suction force acting on an interior side of the ball, where the suction force is generated by the movement of fluid through the central chamber.
