ABSTRACT:
The present invention relates to systems and methods for controlling downhole motors and drilling systems incorporating such systems and methods. One aspect of the invention provides a downhole drilling system including: a downhole motor, a transmission coupled to the downhole motor, and a drill bit coupled to the transmission. Another aspect of the invention provides a method of drilling a borehole in a subsurface formation including the steps of: providing a drill string including a downhole motor, a transmission coupled to the downhole motor, and a drill bit coupled to the transmission; and rotating the drill string while flowing a fluid through the drill string to the downhole motor, thereby powering the downhole motor, thereby rotating the transmission and the drill bit.
