Abstract

Summary

3-C seismic receivers in a single vertical well are used to monitor micro-seismic activity in unconventional reservoirs. In such cases, locations of micro-seismic events depend on a velocity model and a particle polarization of a body-wave arrival. In this abstract, we show evidence for the lack of vector fidelity on downhole receivers. We are presenting a workflow to identify receivers with the lack of vector fidelity and a methodology for correcting the sensitivity of the components of the receiver to preserve the vector fidelity. This methodology enabled us to correct a 13° error in event backazimuth in the presented case study.
