Abstract

Summary

In the context of hydraulic stimulation of unconventional reservoirs, locating induced microseismic events is crucial. It allows mitigating hazards, helps improve the interpretation of the stimulated reservoir volume and optimize the well geometries. To obtain precise hypocenters one should use accurate traveltimes and wide network aperture. In this abstract we improve the aperture of a vertical array of sensors by adding secondary arrivals to the location process.

First, we illustrate the contribution of the multi-arrivals event location algorithm on synthetic data set using the direct and reflected P-waves. Then, we apply the technique to a real data set from Woodford play, Oklahoma, USA. We demonstrate that the use of the additional reflected P-wave improve the location accuracy and allows for a better interpretation of the microseismic data.
