Abstract
A power head for connection in a tubing string suspended in a subterranean location in a wellbore is useful for removing debris from the wellbore. When the power head is in the closed position, well fluids pumped down the tubing string will flow through the power head. When the power head is moved to the open position by dropping a actuator ball onto a seat in the power head, the power head creates flow down along the annulus to circulate debris laden well fluids into a catch apparatus such as a catch basket or screen. In the open position, nozzles and the eductor create the reverse flow.
