Vibrator data were recorded for 15 s with a sampling interval of 1 ms, which after correlation gave 5 s of full bandwidth data. The shotpoint interval was 50 m, using 52 trace streamer at 25 m trace interval, and the total line length was about 15 km. In A new marine vibrator built by Industrial Vehicles Intemational the final displays two adjacent CDPs were added for signal-tonoise (WI) with support from Britoil, was tested in the Gulf of purposes. The test was conducted by GECO Geophysical with Figure 1 shows an enlarged portion of the stacked section obtained support from several major oil companies. The corresponding tests, one of GECO's vessels will be equipped with a set of 6 data window for the air gun data is shown in Figure 2 for comparison.
