Abstract
Systems and methods of down-hole power generation are disclosed, which provide for the generation of electrical power in a down-hole environment for use by down-hole tools such as logging tools, telemetry, and electric control circuit. The electrical generator is operably coupled to a turbine shaft of a hydraulic turbine, and operates at a first rotational speed in response to a rotation of the turbine shaft. The turbine shaft is also coupled to a down-hole actuator such as a rotary drill bit such that the actuator operates at a second rotational speed in response to the rotation of the turbine shaft. A gearbox is operably coupled between the actuator and the turbine shaft to permit operation of the generator and actuator at different rotational speeds by the rotation of the turbines shaft.
