Integrated Core Analysis Frameworks: Unlocking the Potential of Carbon Capture and Storage

Carbon Capture and Storage (CCS) is a critical technology for reducing greenhouse gas emissions and mitigating climate change. Successful CCS deployment relies on a comprehensive understanding of subsurface reservoirs, requiring specialized core analysis distinct from conventional Exploration and Production (E&P) practices. Integrated core analysis frameworks provide an interdisciplinary approach to evaluate both caprock and reservoir characteristics, delivering crucial insights into the long-term behavior and safety of CO2 storage sites. These frameworks underpin computational modeling, calibration, and risk assessment essential for maintaining storage integrity and effectiveness.

This paper introduces a tailored Integrated Core Analysis Framework designed specifically for CCS applications, addressing the unique containment and storage challenges associated with CO2 injection. The framework advances conventional core analysis by incorporating enhanced methodologies in rock mechanics, geochemistry, routine core analysis (RCA), and special core analysis (SCAL). It integrates novel laboratory techniques such as pre- and post-aging studies and detailed mineralogical analyses to better understand reservoir behavior. These enhancements allow for precise characterization of rock properties, stress distribution, and mineral alterations under CO2 exposure. Ultimately, the framework enables accurate prediction of CO2 behavior, mechanical stability assessments, and geochemical interaction evaluations, safeguarding the structural integrity and long-term success of CCS projects.
