f Possibility for monitoring seismic sources in boreholes

In this work, we report a feasibility study for monitoring seismic sources in boreholes. We compute the radiation patterns of borehole sources for different frequency ranges and the load directions. A study of radiation patterns is certainly important and not only to predict all possible seismic events but also to analize the source performance itself. This study has several practical applications: for example, if a source of seismic energy corresponds to a rotational load (as in a drill-bit experiment), the measured three component displacement field can be an indicator to conclude whether the source drilling performance is satisfactory or not.
