Class C's high, early strength gives predictable thickening time and is perfect for use in surface and shallow well applications. GCC's Class C provides superior high-sulfate resistance (HSR) protecting the well from extreme sulfate attack.SDS
More Well Cements
Class G well cement fulfills the onerous requirements of API Specification 10A, such as predictable thickening time, low viscosity, low free fluid, fluid loss control and strength.
GCC's Class H well cement performs excellently in the demanding conditions of deep and horizontal wells and under extreme temperature and pressure. It provides superior high-sulfate (HSR) resistance and protects the well from extreme sulfate attack.
