Abstract
An opening cone for a mechanical stage collar is used during a cementing operation in a wellbore. The mechanical stage collar includes ports activated by the opening cone. The opening cone includes a cylindrical midsection and a conical end section defining a hollow path through the opening cone and a ball suspended in a cage in the cylindrical midsection between a first profile with a first set of ribs and a second profile with a second set of ribs. The second profile is disposed downhole of the first profile and the second set of ribs is pressure rated to rupture at a predetermined pressure and release the ball into the conical end section. The ball is configured to plug the hollow path of the opening cone when released into the conical end section to stop flow through the hollow path.
