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.
