GeoForce® Enhanced Performance Motors
When drilling with mud motors, there are many occasions where bit rotation reduces and increases or the bit/motor may even stall for an instant (microstall). There is often no evidence at the surface for these events, even with detailed observation of the standpipe pressure. The "smoothing out" of fluctuations in drill bit rotary speed and the more consistent torsional loading of the bit can maximize the rate of penetration and reduce wear and tear of internal motor components.
The SperryDrill® GeoForce® motor is designed to offer the highest possible torque throughout the range of maintainable operating differential pressures. Drilling torque is directly proportional to the operating differential pressure across the motor; the higher the operating differential pressure, the higher the output torque.
Benefits
- Greater torque output than conventional motors
- More consistent RPM and torque applied to the bit, increasing ROP, motor life and bit life
- Higher operating temperature ratings for 4 3/4-inch tools (350°F) and 6 3/4- and 9 5/8-inch tools (320°F)
- Improved reliability and performance in harsh environments
- Reduced vibration, improved performance and steerability, increased bit life and better hole quality when run in the FullDrift® bit configuration
- Higher dogleg capability than conventional motors of similar torque output
- More resistant to failures associated with chemical-induced swelling
- Configurations chosen for maximum output using realistic drilling parameters
