Seismic Interferometry in a Crosshole-RVSP Experiment

H009 Seismic Interferometry in a Crosshole-RVSP Experiment F. Poletto* (OGS) L. Petronio (OGS) & F. Miranda (Eni E&P) SUMMARY Seismic interferometry uses the correlation of traces recorded at different locations to simulate virtual sources where only receivers are used. The process provides virtual seismograms with the advantage of enlarging the coverage in seismic exploration. We apply seismic interferometry by using the traces of a mixed borehole/surface survey and process virtual reverse VSP (VRVSP) signals together with crosshole signals. Wireline VSP and surface seismograms were acquired by using vibrator sources at different offsets and receivers installed into two instrumented wells and
