Abstract
A tool for capturing and retaining a pump down plug or ball which has been released from equipment above in a well bore, concealing the pump down plug from subsequent flow of fluid or other material through the tool, and diverting flow from a normal circulation port toward a bypass port through the tool. The pump down plug seats in, and closes, the circulation port, where the pump down plug is then retained by a tubular receptacle. Increased fluid pressure then shears the tool body loose from its housing, moving it downward to a position lower in the housing. This opens the path through which the pump down plug was released from above. A further pressure increase can be used to open the bypass port through the tool body. When the tool body is released from its first position, a diverter can close over the tubular receptacle and divert movement of fluid and other material away from the area of the circulation port and toward the bypass port.
