Sandeep Kumar, SIMULIA Industry Process Consultant, presented Decoding Cement-CO2 Interactions: Geochemical Models Illuminate Well Cement Alterations in CCUS Wells at the SIMULIA Energy Day in Houston, Texas.

Abstract: This presentation explores the intricate chemistry of cement-CO2 interactions within the context of Carbon Capture, Utilization, and Storage (CCUS) wells. Our focus is on deciphering the complexities of cement-CO2 interactions and investigating the alterations occurring in well cement as a consequence of exposure to CO2 in CCUS environments.

Leveraging advanced geochemical models, specifically integrated into Abaqus, this presentation aims to enhance our understanding of the mechanisms governing the cement carbonation process and predict the extent of carbonation in well cementing. Our discussion extends to the implication of carbonation on cement sheath integrity and its crucial role in providing zonal isolation within the wellbore.

To complement theoretical predictions, we incorporate findings from a comprehensive survey of experiments, providing practical insights. The discussion emphasizes the impact of carbonation on cement sheath integrity and its critical role in zonal isolation, contributing to the development of resilient wellbore cement formulations and improved strategies for maintaining long-term integrity in CCUS wells. This comprehensive exploration aims to advance our knowledge and guide practical applications for sustainable CCUS initiatives.
