In this paper we present results from a reduced volume and a hexa-source test recently conducted in the Barents Sea offshore Norway. In this relatively shallow water environment with 200-300m water depth, we show that good quality seismic imaging can be obtained with significantly smaller air-gun source volumes than what the marine seismic industry have traditionally deployed. Furthermore, we present data results from, to the best of our knowledge, an industry first wide source tow hexa-source acquisition, with very high resolution and quality down to the reservoir level of 1-2sec seismic two-way travel time.
