Anisotropy
and Stress Home Seismic anisotropy is caused by well-defined physical factors. My father was a pioneer in measuring split shear waves and quantifying anisotropy caused by 3D stress. He performed real-time monitoring of 3D stress field in underground mines using velocities and attenuations of split shear and longitudinal waves. He used permanently installed zondes. I applied the same rock physics transform to oilfield problems on a larger scale – estimating stresses from seismic data. Milestone publications and presentations 2008 · Bakulin, A. , F. Kets, M.
