Abstract
A downhole cleanout tool includes a tool housing have a fluid inlet and a fluid outlet, and a filter between the inlet and the outlet. The tool includes a pump that is fluidly coupled to at least the fluid inlet to motivate fluid across the filter. The tool also includes a rotatable housing having a nozzle that is fluidly coupled to the pump outlet. The rotatable housing may rotate about a longitudinal axis of the rotatable housing, and the filter and pump may be disposed within the rotatable housing. Each nozzle may include a nozzle outlet oriented at an angle (a) from a radial axis extending from the longitudinal axis of the rotatable housing to a location where the nozzle outlet intersects the periphery of the rotatable housing such that motivation of fluid through the nozzle results in rotation of the rotatable housing.
