Abstract: An apparatus for controlling a downhole tool comprises a generator for generating electricity; a rotor connected to the generator; an electronic circuit electrically connected to the generator; a sensor for sensing movement of the rotor, the sensor being electrically connected to the electronic circuit; and a valve for wellbore fluid and for activating or deactivating a tool or function of the downhole tool, the valve being controllable by being electrically connected to the electronic circuit. The generator is configured to generate electricity to at least the electronic circuit when a flow of wellbore fluid drives the rotor. A corresponding method of controlling a downhole tool comprises configuring the electric circuit to open or close the valve depending on a variation or pattern of a flow rate, controlling the downhole tool.

Abstract: A flow diverter including a bypass element to divert at least a first portion of drilling fluid from a drill string to the borehole annulus. The first portion of fluid, or bypass flow, may be provided to the borehole annulus to clear cuttings generated by a drill bit of a BHA. The remaining fluid flow, or BHA flow, may be expelled through the bottom of the BHA. The fluid discharged through the BHA may enter the annulus and flow upward with the fluid flow diverted through the flow diverter to aid in clearing cuttings. The flow diverter also includes a choke housing disposed concentrically within a drill collar and containing a plurality of chokes to regulate bypass flow. An actuation system may be coupled to the flow diverter to control opening/closing of the chokes and to measure flow rate of the first portion of fluid and/or the remaining fluid.
