Dual-temporal prediction of wellbore condition and phase behavior during transient CO2 injection and leakage in saline aquifers

Key Points

• Wellbore integrity under transient CO2 injection conditions is crucial for ensuring safe storage.
• Modeling predicts phase behavior changes and potential leakage risks over time during CO2 injection.
• Analysis of wellbore conditions integrates transient models to forecast risks associated with CO2 leakage.
• Findings may enable safer geological storage of carbon dioxide in saline aquifers, supporting climate change mitigation efforts.
