Abstract

Systems and methods are disclosed herein for simultaneously milling an obstructions and collecting the resulting debris within a wellbore in an oil-and-gas setting. An example debris collection tool can include a motor, centrifugal pump, gear boxes, bailers, and a pass-through milling bit. A series of shafts can pass through the internal components of the tool and cause various components to rotate when driven by the motor. The gear boxes can lower the speed and increase the torque of rotating downhole components. The tool therefore can simultaneously drive the pump and milling bit at different speeds and torques. The centrifugal pump can include a flow control mechanism at allows the tool to control the flow of drilling fluid from the centrifugal pump into the surrounding subsurface.
