Abstract: A vectored annular cleaning system (VACS) includes a tool body having a first end, a second end, an outer surface and an inner surface defining an internal bore. A valve system is arranged in the internal bore. The valve system includes a valve and an actuator member including a central passage. The actuator member extends from the valve toward the second end. A valve actuator is shiftably connected to the tool body and mechanically connected to the actuator member. The valve actuator includes a plurality of drag blocks and one or more spring members. The one or more spring members radially outwardly bias the plurality of drag blocks.

Abstract: A reverse circulation debris cleanup tool has a pressure control valve that closes up a passage through the body based on a sensed well condition to help pressure control the well when rams close around the tool to isolate the surrounding annulus. The sensor can hold the valve open for a predetermined time to allow debris removal operations and then close. The debris chamber below an eductor in a VACS tool can be thousands of feet long and the valve can provide protection during running in or removal of the tool from well pressure events so as to avoid using shear rams and losing the bottom hole assembly in the borehole and a fishing operation to get it out.

Abstract: A debris management tool including a housing; an opening in the housing; a closure member movable between a closed position and an open position based upon centrifugal input. A method for managing debris in a borehole including rotating the tool as in any prior embodiment at a selected speed to cause centrifugal force to open the closure member; increasing pressure in a fluid surrounding the tool; entraining debris in fluid entering the tool due to differential pressure.
