Lubricants, Cleaners & Sticking-Release Agents
Liquid Lubricants for Drilling Fluids (Standard / Oil-Based / Specialty)
A series of liquid lubricants in standard, oil-based and specialty grades, engineered to reduce mud friction and drill-string wear and to improve drilling efficiency. The range covers water-based and oil-based systems, service temperatures up to 200 °C, and salt- and calcium/magnesium-contaminated environments.
APPLICATIONS
Application scenarios
- 01Torque and drag reduction in directional and horizontal wells
- 02Oil-based and high-temperature salt-saturated muds up to 200 °C
- 03Specialty grade for extreme-pressure lubrication and low-fluorescence requirements

Note: The fluorescence level specification applies only to non-fluorescent liquid lubricants, and the surface tension reduction rate specification applies only to specialty lubricants; other liquid lubricants are not tested for these items.
USAGE
Usage
Add directly to the circulating mud with good mixing; typical dosage is 1.0%-3.0% by weight depending on the target friction reduction. Verify compatibility with the base mud by pilot testing.
