HT RM-100 - High-Temperature Low End Rheology Modifier

HT RM-100 is an advanced rheology modifier specifically formulated for water-based drilling fluids in ultra-high temperature, high-pressure (HTHP), and ultra-deep wells. It provides exceptional low-end rheology control and shear-thinning properties, essential for maintaining gel strengths and ensuring cuttings suspension in challenging environments.

Key Advantages

  • Superior thermal stability up to 240°C (464°F)
  • High salinity tolerance – effective in concentrations up to 150,000 mg/L
  • Low application dosage (0.5–1.5%) for cost-effective control
  • Free-flowing dry powder for easy handling and mixing
  • Environmentally friendly formulation
  • Synergistic performance with other fluid additives

Typical Properties

  • Appearance: White solid powder
  • Product Activity: >95%
  • Viscosity: 50–100 cP @ 1% solution
  • Max Temperature Stability: 240°C (464°F)
  • Solubility: Highly soluble in water

Applications & Recommended Use

HT RM-100 is engineered to maintain viscosity at critical low-end rheology points: **6, 3, 10’ & 10” gel strengths**. This ensures proper hole cleaning and prevents sagging by keeping cuttings suspended efficiently, even in high-salinity environments.

  • Ideal For: Ultra-deep vertical and horizontal HTHP drilling operations.
  • Fluid Capacity: Effective in applications using specific gravities up to 2.0.
  • Concentration: Typical dosages range from 0.5–1.5% by weight, depending on hardness and temperature.

Packaging & Storage

  • Available in 25-pound bags for convenient handling.
  • Store in original packaging in a dry, cool, well-ventilated area.
  • Keep container lids securely closed to prevent moisture absorption.
