Comparative evolution of the families composing the total porosity of the Lavoux a) and the St-Emilion b) carbonates with the CO2 pressure conditions of the experiments (atmospheric, 30, 60 and 90 bar). Three families of porosity are represented: macroporosity A (white), macroporosity B (diagonal lines) and mesoporosity (vertical lines), along with the rock fraction (black).
