Drilling Motors
All Hess DHT mud motors are designed, manufactured and tested in conformance with ISO 9001 and API specifications.
Hess DHT’s Mud Motors are designed with a mud lubricated bearing assembly to withstand high bottom hole temperatures, high operating torques, and high weight-on-bit loads. Bi-directional angular contact thrust bearings are used in this bearing assembly to accommodate weight-on-bit loads and radial loads. An optional near bit stabilizer or eccentric pad can be used with the motor.

About Our Mud Drilling Motors
The Mud Lubricated Bearing Assembly is designed to withstand extreme drilling conditions and high temperatures. This makes it suitable to use with Positive Displacement Power Sections or Turbines. The Bearing Assembly features a high precision bi-directional angular contact bearing pack that gives a uniform load distribution and high weight on bit capacity. In addition, this mud lubricated bearing assembly is radially supported over its entire length and can, therefore, tolerate very high side loads.
Features:
- Designed using state of the art technology
- Ball Bearings generate less friction than carbide/diamond button bearings
- Bi-Directional Angular Contact Bearing Pack – Tensile or compression load is supported by all 14 Bearings
- Bearing Assembly is radially supported over its entire length
- Special Tungsten Carbide Flow Restrictors – Highly resistant to wear, inherently stronger than our competitor’s tool.
- Short bit-to-bend length
- Increased reliability – No Belleville Springs, our Motors have logged thousands of drilling hours in the harshest conditions
- Maximum operating temperature is 350 degrees Fahrenheit (Limited by power section operating temperature)
- Can be run with Positive Displacement Power Sections or Turbines
Benefits:
- Higher operating temperatures
- Higher radial load capacity
- Easy to service; Beneficial in remote locations
- No chain reaction failures
- Versatile; Operates in a wide variety of drilling fluids
- Higher dynamic weight-on-bit capacity
