Black Viper engineers calculate the hydraulic power input to the motor and the mechanical power output of the motor, based on measurements of weight-on-bit (WOB), torque, bit rotational speed and pressure drop across the motor. Input and output values are plotted against one another to produce a torque curve, which indicates maximum achievable power output of the motor.

The WOB can then be adjusted for the given characteristics of the rock structures to be encountered in drilling. Optimum standpipe pressure, operating efficiency, and wear of the motor are also determined.

The hydraulic power required to drive the downhole PDM and drill bit is often less than the mechanical power required to drive the rotating drill string.

Matching the right PDM to the right drill bit is a critical step in the process. Our custom designed PDC bits are specifically designed for the directional drilling industry. They are extremely stable, durable and directional “friendly.”

The PDM utilizes a bent housing between the motor section and the mud lubricated bearing assembly which contains anti-friction bearings. The rugged articulated driveshaft is sealed and lubricated for long service.

Black Viper has designed and is manufacturing our own line of mud lubricated high-performance mud motors. Included in this process is a larger, more robust bearing assembly that utilizes larger bearings in the bearing pack. We use high-tech, Space Age metals in the bearing assembly, cryogenically treated to reduce wear and increase the life of the motor.

The reliability of the drilling motor combined with our custom drill bit designs and MWD systems present attractive alternatives to rotary drilling.

With over 100 years combined experience in directional and horizontal drilling technology, Black Viper can help achieve optimum results in minimum time.
