Abstract
A downhole drilling motor assembly includes a first motor, a second motor aligned coaxially with the first motor, and a clutch assembly aligned coaxially with the first and second motors. The clutch assembly independently and selectively actuates each of the first and second motors to rotationally drive a drill bit. A related method includes: mounting a drill bit at a distal end of a drill string at a well site; and providing a downhole drilling motor assembly which rotationally drives the drill bit. The clutch assembly is controlled to independently and selectively actuate the first and second motors, and the drill bit is rotationally driven via the independent and selective actuation of the first and second motors.
