Abstract:
A bearing section for a positive displacement mud motor for directional drilling in which the deflection of the drill bit is remotely adjusted by bending the drive sub using an offset flex drive mechanism to adjust between desired settings. The bearing section is adjustable from the surface without the need for trips of the bottom hole assembly to the surface.

Claim (Index 13):
The method of directing a positive displacement mud motor of  claim 12 , in which the offset flex drive mechanism comprises a fixed adjustment ring segment fixed to the inside of the outer housing at a location central between the lower end and the upper end; a plurality of electromagnets embedded in an inner surface of the fixed adjustment ring segment; a moving adjustment ring segment, located inside the outer housing at a location central between the lower end and the upper end; the moving adjustment ring segment being movable rotationally within the outer housing from a neutral position on an opposite side of the inside of the outer housing from the fixed adjustment ring segment to a bent position in which the moving adjustment ring segment is in contact with the fixed adjustment ring segment; and a plurality of permanent magnets embedded in a surface of the moving adjustment ring segment which is adjacent to the inside surface of the outer housing when the moving adjustment ring segment is in the neutral position and which is in contact with the fixed adjustment ring segment when the moving adjustment ring segment is in the bent position; and the step of the control circuit activating the offset flex drive mechanism comprises the control circuit changing a polarity of the plurality of electromagnets.
