Enhanced oil recovery (EOR) by carbon dioxide (CO 2) injection is a critical technique in the
decarbonization process of the world. This method involves injecting CO 2 into existing …

The past two decades of research on Carbon Capture and Storage (CCS) seem to have
finally become fruitful as global leaders and energy-intensive industries are cooperating to …

CO 2 geological utilization and storage (CGUS) is an important technology to achieve a
deep cut of global CO 2 emissions. CO 2 leakage from the subsurface may impair the …

Deep saline aquifers are among the most favorable geological sites for short-and long-term
carbon geosequestration. Injection of CO2 into aquifers causes various hydro-physical …

CO 2 sequestration is an effective technology for reducing greenhouse gas effect. To ensure
the safety, assessment of well applicability should be conducted before CO 2 sequestration …

Maintaining well integrity is critical to the success of geologic carbon storage (GCS) and
carbon dioxide enhanced oil recovery (CO 2-EOR) operations. Wells that experience …

Presence of microannuli at the cement interfaces in wellbores could provide a path for fluid
leakage. In this study, we combined experimental analysis and numerical modelling to …

Depleted hydrocarbon reservoirs are a promising target for CO 2 sequestration. Injection of
cold CO 2 into such geological reservoirs will cause thermal stresses and strains in wellbore …

Many studies on CO 2 injection monitoring focus on fault stability risks due to increased pore
pressure. However, the temperature of the injected fluid can also significantly impact the …

Abstract In Carbon Capture and Storage (CCS) procedures, it is important to determine the
stability of the wellbore during carbon dioxide (CO2) injection and part of this involves …
