Description
The following files (.xlsx) are included:
--- Regarding Figure 3 /file Dry-5 and 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.
