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 14):
The method of directing a positive displacement mud motor of  claim 12 , in which the offset flex drive mechanism comprises an adjustment gear mounted within the outer housing by an extension fitting within an offset bore in a mounting sleeve mounted inside the outer housing at a location central between the lower end and the upper end, the adjustment gear having an offset bore through which the flexible drive sub passes; a pinion gear rotationally coupled to the adjustment gear, mounted on a shaft with a driven gear on an opposite end from the pinion gear; a driving gear fixed on an outside of the flexible drive sub; and a control shaft actuator coupled to the control circuit for axially moving the shaft from a position where the driven gear is disengaged from the driving gear to a position where the driven gear engages the driving gear; and the step of the control circuit activating the offset flex drive mechanism comprises the control circuit causing the control shaft actuator to axially move the control shaft to engage the driven gear and the driving gear for a time sufficient to change between the neutral position and the bent position.
