Capillary Pressure Effects in the Geological Storage of Carbon Dioxide
Carbon capture and storage has been identified as a key technology in the global effort to reduce carbon emissions and mitigate the adverse effects of climate change. In this thesis we present a series of theoretical and experimental studies pertaining to surface tension effects in the geological …

Modeling CO₂ leakage from geological storage formation and reducing the associated risk
Large-scale geological storage of CO₂ is likely to bring CO₂ plumes into contact with existing wellbores and faults, which can act as pathways for leakage of stored CO₂ Modeling the flux of CO₂ along a leaky pathway requires transport properties along the pathway. We provide an approach based on …

Microscopic study of salt precipitation dynamics during the injection process of CO2 storage in saline aquifers
… by 2050. Carbon Capture, Utilization, and Storage (CCUS), especially geological CO₂ storage in saline aquifers, can store billions of tons of CO₂. However, salt precipitation during injection can clog pores and reduce permeability. Understanding the dynamics of this process, influenced by …

Studio preliminare per la valutazione della fattibilità di un progetto di CO2-ECBM nel bacino carbonifero del Sulcis
Nowadays CO2 geological storage represents a valuable alternative to reduce greenhouse gases release into atmosphere. Correct identification of the location for a suitable reservoir is a complex decisional process because it must consider a great number of criteria mainly concerning environmental, …
