HT RM-100 - High-Temperature Low End Rheology Modifier
HT RM-100 is an advanced rheology modifier specifically formulated for water-based drilling fluids used in ultra-high temperature, high-pressure, and ultra-deep wells (both vertical and horizontal). Designed to deliver exceptional low-end rheology control, this polymer combined with other components enhances the viscosity of drilling fluids, ensuring optimal hole cleaning and cuttings suspension under extreme conditions. With excellent stability in freshwater and high-salinity brines, HT RM-100 provides superior shear-thinning properties, making it an essential additive for maintaining low-end gel strengths in challenging drilling environments.
Advantages
- Free-flowing dry powder for easy handling and mixing
- High salinity tolerance – effective in brine concentrations up to 150,000 mg/L
- Low application dosage (0.5–1.5%) for cost-effective viscosity control
- Environmentally friendly formulation with minimal ecological impact
- Superior thermal stability – remains effective at temperatures up to 240°C (464°F)
- Works synergistically with other rheology modifiers and fluid additives for optimized drilling performance
Applications & Recommended Use
- High-temperature, high-pressure (HTHP) drilling operations
- Freshwater and high-salinity brine drilling fluids
- Low-end rheology control in ultra-deep wells
- Drilling operations requiring effective cuttings suspension and fluid stability
- Applications using specific gravities up to 2.0
HT RM-100 is designed to optimize the low-end rheology parameters of high-performance water-based drilling fluids in ultra-deep, high-temperature, and high-pressure wells. It effectively controls viscosity, enhances hole cleaning, and reduces the risk of wellbore instability.
This product is ideal for:
HT RM-100 is engineered to create and maintain viscosity at the critical low-end rheology points: 6, 3, 10’ & 10” gel strengths. It ensures proper hole cleaning and prevents sagging by keeping cuttings suspended efficiently, even in high-temperature and high-salinity environments.
Recommended treatment levels vary depending on total hardness, solids content, and temperature conditions, with typical concentrations ranging from 0.5–1.5% by weight.
