CEMENTING SOLUTIONS / CEMENT RETARDERS

MTR™ & HTR™

MTR™

MTR™

Applications
  • Global use
  • Freshwater, seawater or saltwater
  • 120-250°F (50-120°C)
  • All cements, including reactive cement
Advantages
  • Linear thickening time response with both temperature and concentration
  • Improved test-to-test repeatability
  • Extreme right-angle set thickening time curves
  • Minimal inhibition to early compressive strength development
  • Does not cause early or middle test viscosity humps
  • Can be delivered as a water-based liquid additive

HTR™

HTR™

Applications
  • Global use
  • Freshwater, seawater or saltwater
  • High-temperature performance: 250-380°F (120-195°C) or higher with an intensifier
  • All cements, including reactive cement
Advantages
  • Linear thickening time response with both temperature and concentration
  • Improved test-to-test repeatability
  • Extreme right-angle set thickening time curves
  • Minimal inhibition to early compressive strength development
  • Does not cause early or middle test viscosity humps
  • Does not require a retarder intensifier even up to 380°F (195°C)
  • Can be delivered as a water-based liquid additive

Mid- and High-Temperature Cement Retarders

Generic mid- and high-temperature retarders pose a number of operational challenges, including issues with repeatability, linearity and correlation of pilot blend to field blend. At certain temperatures, retarders can be inconsistent—further complicating the design process and potentially placing the cement job at risk. MTR™ and HTR™ have been engineered to minimize or even eliminate these issues.
