Abstract

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