Abstract

Summary

Wave propagation in unconventional reservoirs can be very complex. Both thin layering and hydraulic fracturing perturb significantly the wave field that propagates in such formations, showing potential strong anisotropic effects. Therefore, the accuracy of the numerical simulations of travel times, amplitudes and polarization is critical for the purpose of microseismic monitoring: these parameters are indeed used in events locations and characterization (source mechanism and magnitude). While there exists a wide variety of finite-difference schemes aimed at solving the Eikonal equation in anisotropic media, it is necessary to solve transport and polarization equations to get the other three parameters instead of using the traveltime gradients to infer them. In the present paper, we propose a finite-difference, perturbation based scheme to solve for all three equations in 3D VTI velocity models.
