ATV logs, ellipticity data, and stress inversion results from boreholes in the BedrettoLab

This dataset contain ATV logs, ellipticity data, and stress inversion results from borehole CB1(MB1), CB2(MB2), CB3(MB3), MB4, MB5, MB8, ST1, and ST2 in the Bedretto Underground Laboratory (BedrettoLab). The ATV.zip file contain the acoustic amplitudes, traveltimes, traveltime-derived borehole radii, and binary masks of the borehole damage areas (breakouts, keyseats, and pre-existing fractures). The ellipticity.zip file contain the ellipticity data derived from the ATV traveltime log of each borehole, including the ellipse axis azimuths and ellipse axis ratios of the ATV-measured borehole cross-sections. The stress_inversion.zip file contain stress data inverted from ellipticity of each borehole, including the principal stress orientations and relative stress magnitudes.
