Abstract
SUMMARY Nowadays microseismic monitoring technology is widely used for the field control of hydraulic fracturing used in the production of unconventional hydrocarbon and geothermal resources. In the paper I show my results on developing software with graphic-user interface for microseismic data processing. It allows interactive processing including trigger-files extraction, band pass filtering, arrival-time picking, polarization analysis. This software was applied to process real dataset with a particular focus on polarization analysis of shear waves. Polarization analysis revealed evidence of splitting (cross-type shape of polarization hodogram). It is an important observation as it proves anisotropic properties of rocks treated by hydrofrac.
