Abstract
A debris cleanup tool uses a movable eductor to reconfigure the flow scheme through the tool. During the debris pickup mode, pressurized fluid is delivered to through the tubing to the eductor inlet. The outlet of the eductor is into the surrounding annulus where the flow splits with most going to the surface and the rest down and into a mill making cuttings. The flow into the mill takes the cuttings to a collection volume and then screens the internal flow stream before directing it into the eductor inlet. The eductor body can be repositioned to close the eductor outlet to the annulus and open the outlet into the housing to allow reverse flow. In one embodiment a ball is dropped and pressure is built to break a shear pin to shift the eductor body and to open a bypass around the ball.
