Abstract

A method is disclosed for drilling a wellbore. The method includes operating a turbine-type mud motor having a bi-center drill bit coupled to it, and applying an axial force to the bit which is selected so that the bit drill:, in a directionally stable manner. In one embodiment, the motor is a steerable motor operated to maintain a selected trajectory of the wellbore.
