Abstract: A borehole plug or packer for treating is designed to be flowed back to a surface location after use. When the treatment is concluded pressure from above is relieved or lowered, and well fluid is flowed back, so that the plug or plugs disengages at slips designed to resist differential pressure from above. The application of differential pressure from below causes the lower slips to release one or more of such plugs in the hole into specialized sub surface or surface capture equipment so that well pressure is relieved before removal of the plugs from specialized subsurface or surface capture equipment. Sensors to obtain and store data can be incorporated into the plugs or into objects landed on the plugs so that when brought to the surface the data can be processed and used in aid of production.

The application of differential pressure from below causes the lower slips to release one or more of such plugs in the hole into specialized sub surface or surface capture equipment so that well pressure is relieved before removal of the plugs from specialized subsurface or surface capture equipment. At least one apparatus is used to bridge transitions in wellbore dimension on the way to the surface and close the gaps to allow produced formation fluid to continue taking a packer or plug past the well diameter transition.

Packers or plugs are captured above, below or at a wellhead in a receptacle. Production ensues without milling with the captured plugs or packers in place or removed.

Abstract: A valve assembly for a plug to close off a zone in the well for further treatment above the plug features a valve member initially pinned in an open position where flow up to a predetermined level can move through without dislodging the valve plug to move to its associated seat. If the perforating gun misfires a replacement gun can be run in with flow as the plug is still retained in the position for flow through the plug. On the other hand flow around the plug above a predetermined level will shear retainers for the plug and let the plug land on its seat closing flow in a downhole direction for treatment.
