ABSTRACT:
A body and driveshaft extension for down hole drilling motors to allow the down hole assembly to operate as part of a drill string responsive to selected manipulations of the drilling fluid flow rate, carried out at the earth surface, to assume either a straight hole drilling configuration or a directional drilling configuration by choice of the driller.
In the directional drilling configuration, the drill head driving output shaft rotates about a centerline deflected from the motor general centerline. The point of deflection is between the drilling motor and the drill head.
