Abstract
A method and apparatus for wellbore control include a downhole facing ball stop and sealing area that can stop and seal with an actuator ball migrating toward surface with wellbore returns or production. The downhole facing ball stop operates with the returning actuator ball to create a seal against any returns or production migrating toward surface such that well control is provided until the ball is removed from the sealing area or a bypass is opened around the seal.
