Source-geophone azimuth from 3-C seismic polarization
Saúl Ernesto Guevara, Robert R. Stewart
The source-geophone azimuths from an offset source shot into a 3-C seismic line (over the Blackfoot field, Alberta) are determined using polarization analysis. We find that the refracted S-wave arrivals, P-S reflections, and ground roll all give good estimates of the actual shot-receiver geometry. First-breaking P-wave energy does not provide a consistent direction of arrival.
