Reservoir Aspects of CO2 Sequestration

The reduction of CO2 emissions is one of the critical enablers for humanity to continue to rely (partially) on hydrocarbons as source of energy. CO2 storage in saline aquifers or depleted oil and gas fields could potentially contribute for diminishing CO2 emission into the atmosphere and mitigate its adverse effects on the climate. Our research focused on the physical-chemical numerical modeling of CO2 injection into geological formations. The goal is to provide the basis for the development of new models and numerical tools capturing more realistically a spectrum of important physical effects (thermodynamics of water-hydrocarbon-CO2 systems, dissolution and precipitation of minerals, interfacial phenomenal, etc.). Ongoing projects, were conducted mostly as part of the CATO program. They are aimed at a better description of wettability changes in rocks, natural convection and dry-out and sal-precipitation induced by CO2 injection.
