Abstract

Summary

This paper examines the impact of anisotropic dispersion on P-wave reflections. We show a modest effect on the amplitude and large effect on the phase, the latter of which could be mistaken for azimuthal velocity variations. We present a Bayesian inversion based on a forward modelling technique aimed at recovering layer thickness, fracture density, and fracture length in a thin-layer example. Our results show that the large-scale fractures can be clearly distinguished from microcracks despite the presence of interfering reflections, provided we have a sufficiently accurate background velocity model.
