Changes in pore structure and mechanical properties of sandstone reservoir during supercritical CO2 geological sequestration

Key Points

• Alterations in mechanical properties were observed during supercritical CO2 exposure, highlighting significant changes.
• The study specifically measured pore structure variations and mechanical strength in sandstone reservoirs over time.
• This analysis employed observational methods to assess the impact of supercritical CO2 on reservoir integrity and performance.
• Findings suggest the need for careful consideration of pore structure changes in carbon capture applications.
