Integration of local materials for their use in oil well cementing

Abstract: Algeria has several minerals that can be incorporated into the production of petroleum cement. Indeed, this work mainly focuses on the effect of incorporating non-reactivated barite into a class G clinker intended for the cementing of oil wells, and thus producing a local petroleum cement. The research methodology involves a systematic study of the effects of partial replacement of clinker with various proportions of barite (10, 20 and 30%) on properties such as mechanical properties, setting time, density and specific surface area (SSA) of the cementitious system. Advanced techniques such as the ZETIUM analytical machine are used to analyze the mineral compositions and assess the influence of these replacements. A comprehensive testing program is conducted to evaluate the performance of the new G-grade petroleum cement, including compressive and flexural strength tests, with emphasis on parameters relevant to oil well cementing applications. The results obtained demonstrate the potential of partial replacement of clinker in the manufacture of a new class G petroleum cement. The optimized composition presents comparable or improved mechanical properties compared to traditional sulfate-resistant Portland cement (SRC). In addition, the reduced dependence on clinker with the integration of barite as a replacement material contributes to a decrease in greenhouse gas emissions and energy consumption, in line with the objectives of sustainable development and environmental preservation.
