This high-temperature extreme pressure lubricant is a high-performance, environmentally friendly additive designed for water-based drilling fluids operating under severe downhole conditions. Utilizing a unique chemisorption mechanism, this high-temperature extreme pressure lubricant forms a continuous, tenacious lubricating film on metal surfaces, including drill strings, bottom-hole assemblies (BHA), and casings. As a non-hydrocarbon, non-fluorescing additive, this advanced high-temperature extreme pressure lubricant is safe for personnel, environmentally compliant, and has no adverse effect on wireline logging operations.
The lubricant's molecular structure contains active polar groups that chemically bond to metal surfaces through chemisorption, creating a durable, multi-layer lubricating film that withstands extreme pressures and temperatures. This film remains effective under contact pressures exceeding 50,000 psi and temperatures up to 400°F (204°C), providing reliable lubrication in the most challenging drilling environments. The synthetic base ensures consistent performance without the variability associated with mineral oil-based products.

Recommended Treatment
A typical treatment range of 0.5–2% by volume is recommended, with specific dosage adjustments based on well geometry, temperature, pressure, and drilling fluid properties. For optimal performance, add the High-Temperature Extreme Pressure Lubricant gradually during fluid mixing to ensure uniform distribution and maximum film formation on metal surfaces. Continuous monitoring and adjustment are advised in response to changing downhole conditions.
