Abstract
Carbon (IV) oxide (CO2) geosequestration represents one of the most promising options for reducing atmospheric emissions of CO2. Capturing carbon dioxide is proposed as one solution to global climate change caused by anthropogenic gases in the atmosphere. CO2 can be stored in aquifer or depleted oil and gas reservoirs. Caprock integrity is assessed based on petrophysics and geomechanics. Theories of rock failure is vital for caprock integrity (factor of safety estimation). Caprock integrity is monitored using Machine Learning. The aim of this study is to evaluate caprock integrity under cyclic stress loadings and identify best reservoirs for CO2 storage. The authors will investigate the impact of pressure on caprock integrity during CO2 injection and evaluate the extent machine learning models can predict caprock integrity.
