While wide-azimuth seismic surveys represent a routine in land environments, in marine environments things go differently. Conventional offshore 3D acquisition is still being performed mainly using narrow azimuth streamer configurations, even in structurally complex areas. Attempts at breaking this paradigm have been recently made by the industry with good results, through the acquisition of some unconventional “Multi Azimuth” (MAZ), “Wide Azimuth” (WAZ), “Rich Azimuth” (RAZ) and Coil Shooting marine surveys. Here we are presenting planning, acquisition and processing results of the advanced marine surveys, a Multi-Azimuth and a Coil shooting (Full azimuth), recently acquired by Eni e&p in Indonesia. We are also presenting a 2D test and successive 3D acquisition of a broad bandwidth (dual sensor) seismic in West Timor area, aimed at exploiting sub thrust geology. At the end we demonstrate that advanced acquisition techniques effectively provide improved geophysical images and more geological insight for exploration compared to traditional techniques.
