Abstract

We present an analysis of guided waves generated by microseismic events in the low-velocity Eagle Ford shale. The relative strength of guided wave energy is used to qualitatively differentiate between events that are occurring inside and outside of the Eagle Ford. The dependence of guided wave energy on event depth is first confirmed through synthetic modeling, with dispersion curves predicted from an analytical solution being used to separate between direct arrivals and guided waves. A qualitative differentiation criterion is developed, and then successfully applied to real data that suffer from large depth location uncertainty.
