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.

Method and apparatus for wellbore control

A method for fluid treatment of a borehole including a main wellbore, a first wellbore leg extending from the main wellbore and a second wellbore leg extending from the main wellbore, the method includes: running a wellbore tubing string apparatus into the first wellbore leg; conveying a plug into the wellbore tubing string apparatus to actuate a plug-actuated sleeve in the wellbore tubing string apparatus to open a port through the wall of the wellbore tubing string apparatus covered by the sleeve; employing a plug retainer to retain the plug in the tubing string against passing outwardly from the tubing string apparatus; allowing fluids to flow toward surface outwardly from the tubing string apparatus; and performing operations in the second wellbore leg.
