At the laboratory scale, carbonate rocks already do not show astrong correlation between P- and S-wave velocities and porosity. The velocity disparitiesbetween carbonates of similar mineralogy and porosity result from different microstructuresderived from their sedimentary facies and subsequent diagenetic transformations. The stilldiscussed applicability of Biot-Gassmann’s equation for fluid substitution in carbonate rocksremains another key issue. We propose an integrated experimental workflow that allows aconsistent checking of the applicability of Biot-Gassmann’s equation and provide key geologicaland microstructural information to understand the petroacoustic signature of carbonate rocks.This approach is implemented on samples representative of two different carbonate formations.The obtained results demonstrate the applicability of Biot-Gassmann's equation for the twostudied carbonate families and show the interrelation of mineralogy and porosity distribution intheir acoustic response. %G English %2 https://ifp.hal.science/hal-02299332/document %2 https://ifp.hal.science/hal-02299332/file/Consistent%20Experimental%20Investigation.pdf %L hal-02299332 %U https://ifp.hal.science/hal-02299332 %~ SDE %~ IFP %~ GIP-BE
