KLASS G (HSR) 

Reference standard: API Spec 10A; ГОСТ 1581–96

Producer: NORM Cement Plant

Areas of use

KLASS G (HSR) is Portland cement with high sulfate resistant characteristics, designed for cementing work in the drilling of oil and gas wells.

Applications

  • Oil Wells construction
  • Water wells
  • Gas wells
  • Pipelines
  • Foundation works on offshore platform support bases
  • For cement plug

Advantages

Given the complexity of the application and extreme conditions of temperature and pressure, well cement HSR class G fulfills demanding requirements, such as a predictable thickening time (set time), high sulfate resistance, long-term performance, fluid loss control, low viscosity and mechanical resistance.
