Mud Motors

National Oilwell Varco offers the most versatile array of downhole motors available for straight or directional drilling. Rotary power is produced by a Monoflo positive displacement progressing cavity mud motor. The mud motor power sections offer a wide range of bit speeds and torques and can be tailored to function in both high bottom-hole temperatures and inverted mud systems. Motors are available with a fixed or an adjustable housing located between the motor and the bearing assembly. The adjustable housing is easily rig adjustable from zero (or straight) to a three-degree bend in 12 increments or a four-degree bend in 18 increments.

Most motors have an optional near bit stabilizer. Concentric or eccentric stabilizers or pads can also be provided to stabilize the top or middle of the motor.

National Oilwell Varco manufactures motors from 1 7/16" to 11 1/4" diameter and offers sales and service support via an international network of facilities.
