Abstract

Microseismicity is better observed when receivers are located in wells, because the ambient noise is much lower. On the other hand, the standard Wadati’s method is not reliable for estimating the time origin in that case, as the Vp/Vs ratio can not be assumed to be constant for all events. This problem can be fixed adding further receivers at the Earth surface for the time origin estimation. Finally, using jointly surface and borehole receivers, we can better locate the hypocentres, illuminate the reservoir by seismic tomography and highlight possible fluid pathways. The enhanced Earth’s images so obtained can enhance processes as hydrocarbon production, gas storage and CO2 sequestration.
