HT CAP-100 - High-Performance Encapsulator

HT CAP-100 is a high-performance encapsulator engineered for water-based drilling fluids in high-temperature, high-pressure (HTHP), and ultra-deep wells. This synthetic polymer inverse emulsion delivers exceptional shale inhibition and cuttings encapsulation, ensuring maximum wellbore stability in extreme drilling environments.

Key Features & Benefits

  • Ultra-High MW: Exceeds 10 million for superior performance
  • Temp Stability: Stable up to 375°F (190°C)
  • Ionic Tolerance: Exceptional Calcium (Ca²⁺) & Magnesium (Mg²⁺) resistance
  • Fast-Acting: Liquid inverse emulsion for rapid dissolution
  • Efficiency: High performance at dosages as low as 0.1%

Technical Specifications

  • Appearance: Off-white liquid
  • Polymer Activity: 28% – 32%
  • Viscosity: 300 – 1500 cP
  • Pour Point: < -20°F (-29°C)
  • Solubility: Highly soluble in water
  • Rheology: Minimal impact on optimized properties

Applications & Recommended Treatment

HT CAP-100 is ideal for unconventional formations, directional drilling, and extended-reach wells. It works in synergy with shale inhibitors, sealing agents, and lubricants to maintain wellbore integrity.

  • Dosage Range: 0.35 – 5 lb/bbl (1 – 14 kg/m³) based on shale lithology.
  • Implementation: Add alternatively with other additives to maintain fluid properties.

Packaging & Storage

  • Available in 265 Gal (900 Kg) totes (IBCs) or 55 Gal (180 Kg) drums.
  • Store in original containers in a dry, cool, well-ventilated area.
  • Protect from extreme temperatures to maintain product integrity.
