- The following files (.xlsx) are included: --- Regarding Figure 3 / Dry-15MPa The elastic modluli of the dry sample. The data are obtained directly from stress-strain apparatus. --- Regarding Figure 4/file Brine Brine saturated sample : the elastic moduli of fully brine saturated sample. --- Regarding Figure 5 / file V1+V2 The influence of the dead volume : the bulk moduli from the measurement as the dead volume changed. --- Regarding Figure 6/ file Oil Brine saturated sample : The elastic moduli when the sample is saturated with oil. --- Regarding Figure 7/ files Brine&oil The bulk modulus and attenuation at apparent frequencies --- Regarding Figure 10/ files Vp_Vs_dry Vp and Vs velocities and the deduced aspect ratio, crack density distribution and crack porosity (introduced in the paper). --- Regarding Figure A2/ files Data_uncertainty Data measured at different time and different traces, which are used to estimate the uncertainty of the the attenuation.
