Abstract
A mud turbine apparatus includes a rotor including an inner ring configured to be positioned around a drill pipe, an outer ring that is positioned around and spaced apart from the inner ring, a plurality of magnets coupled to the outer ring, and a plurality of blades coupled to and extending between the inner ring and the outer ring. The apparatus also includes a stator including a housing configured to fit into an annulus between the drill pipe and a surrounding tubular, and to receive the outer ring at least partially therein, and a plurality of coils that communicate with the magnets, such that in a first mode of operation, the rotor rotates to assist fluid flow therethrough and decrease drilling fluid pressure in the annulus, and in a second mode of operation, the rotation of the rotor impedes fluid flow therethrough and increases drilling fluid pressure in the annulus.
