Results from a 3D field trial with a seismic acquisition and processing method based on continuous wavefields

This paper describes the acquisition setup and results from a field trial conducted with a novel marine seismic acquisition and processing methodology that utilizes continuous wavefields. Compared to a conventional survey previously acquired in the same location, both the peak sound pressure and sound exposure levels were reduced significantly. The lateral sampling was improved and trace density increased without loss of acquisition efficiency. The imaging results of the field trial data show deep penetration equivalent to the conventional data despite the significantly lowered source output.
