Investigating the Compressive Strength Plateau of Geopolymer Cement under HPHT

The modern oil and gas industry excessively uses Ordinary Portland Cement (OPC) as their preferred cementing choice. However, the industry is quickly realizing that OPC’s mechanical properties fail to uphold its objectives in deeper wells with higher temperature and pressure. Due to its weak ceramic characteristics, Ordinary Portland cement’s mechanical performance is limited, especially in wells with high temperature and pressure. Comparatively, Geopolymeric materials can better tolerate these work conditions. The scope of study is mainly on designing Geopolymer cement compositions, preparing class G cement composition and testing in accordance to the American Petroleum Institute. The obtained results will be compared in terms of compressive strength with class G cement slurries. The study will comprise standard weight cement slurry.
