Z-99 AN EVALUATION OF PEAK AND BUBBLE TUNING IN SUB-BASALT IMAGING: MODELLING AND RESULTS Summary
As part of the iSIMM project (White et al. 2002), a 6,360 in 3 airgun source array was used to shoot twice a deep seismic profile into a 380 km array of Ocean Bottom Seismometers (OBS) east of the Faroe Islands. The first pass used peak tuning, and the second used bubble tuning, with other source pa...

| Summary: | As part of the iSIMM project (White et al. 2002), a 6,360 in 3 airgun source array was used to shoot twice a deep seismic profile into a 380 km array of Ocean Bottom Seismometers (OBS) east of the Faroe Islands. The first pass used peak tuning, and the second used bubble tuning, with other source parameters constant. The objective was to deliver low frequency energy for deep, long-offset, sub-basalt penetration. The results suggest that towing large guns deep is more important than the tuning method. However, for the gun configuration used, the bubbletuned data are more compact, less reverberant and easier to pick. |
