Abstract
A seismic prospecting method allowing positioning in space of geologic events in the neighborhood of a well and calculation of the dip and the direction of dip. Seismic waves are transmitted into the formation, and three-axis seismic sensors placed in the well and coupled with the formation surrounding the well receive seismic data corresponding respectively to components along the three axes of seismic waves reflected by discontinuities in the formation in response to the transmitted seismic waves. Orientation data defining orientation in space of the three-axis seismic sensors is assigned to the seismic data. Processing operators corresponding to the three components are applied in parallel to the seismic data, allowing selection, from polarized waves received at each of multi-axis sensor, of P or S seismic waves useful for characterization of the formation in a neighborhood of the well, locating in space, at each of the multi-axis sensors, respective origin directions of the polarized waves, and positioning in space of the seismic events that generated the polarized waves.
