About

Dr. Olga Vizika-Kavvadias holds a Diploma and a Ph.D. in Chemical Engineering (University of Patras). Since 2013 she is Director of Geosciences at IFP Energies Nouvelles. Her relative research activity is focused on: Water Alternate Gas (WAG) processes, gas condensate and depressurization of mature fields; Experimental investigation and modeling of transport properties of gravity drainage, gas injection processes; Modeling of phenomena occurring during reactive flows in porous media with applications to the geological storage of CO2; Experimental investigation and modeling of the effect of microstructure and heterogeneities at different scales on the displacement mechanisms and macroscopic flow properties of sandstones and carbonates.
