Compare to the even wall downhole motors the conventional downhole motors are widely used in oil and gas well drilling because of the big cost advantages. In oil and gas well drilling operations the reliability is more important than any other factors. We provide most reliable downhole motors to customers to help them saving as much drilling cost as possible.
To fit different bore hole environment we provide different power sections as follow:
- Clean Water Base Mud Power Sections
- Salty Water Base Mud Power Sections
- Oil Base Mud Power Sections
- High Temperature Power Sections
- Hard Rubber Power Sections
Besides we also accept custom making orders as per customers’ detailed technical requirements.
