“…First, stacking velocities from the surface seismic survey were used to remove the normal moveout of the traces and traces stacked for each shot gather ( Figure 7). Then a VSPCDP transformation was performed on the entire hydrophone data using a technique outlined in Stewart et al (1998). Reflections on the VSPCDP stacked traces (Figure 8) were observed to correlate to the structural stack of the surface seismic section supplied by a contractor.…”

acquired a high-resolution 3C-2D seismic survey at the Blackfoot field located east of Calgary. To test the feasibility of vertical cable acquisition in a land environment, a 48-channel hydrophone cable was deployed in a 100 m cased and water-filled hole located in the centre of the profile. The additional hydrophone channels were patched into the surface recording spread which allowed for the simultaneous recording of all 151 dynamite shots into the surface geophones and the vertical cable. Initial results of a VSPCDP stack of the entire hydrophone data revealed a continuity of reflectors across the section and good correlation with the surface seismic results. An average of the VSPCDP stacked traces near the hydrophone cable spliced between the surface seismic section demonstrated the ability to obtain reliable images from the hydrophone cable data.
