Abstract
A reaming tool includes a housing having a connection at one end for coupling to a pipe string. The housing defines at least one of a rotor and a stator of a turbine. A rotor shaft is rotatably supported on the housing. The rotor shaft has an interior passage and defines the other of a stator and a rotor of the turbine. The rotor shaft has a coupling at one end to attach a well intervention tool. A flow diverter is disposed within the housing. The flow diverter comprises ports to selectively direct flow of fluid from an interior of the housing to either (i) an annular space between the housing and the rotor shaft, or (ii) the interior passage of the rotor shaft. The flow diverter is operable to change direction of the flow of fluid by changing a flow rate of the flow of fluid.
