A Field Trial of a Multi-sensor Broadband Seismic Streamer at the Oseberg Field

A new seismic streamer technology, Isometrix, has been developed by WesternGeco. The technology is a multi-sensor marine seismic streamer that measures the full vector of water particle motion, in addition to pressure, and enables separation of the up-going (signal) and down-going (ghost) components of the wavefield, plus a high fidelity calculation of the wavefield between streamers. During the summer of 2011 a field trial of Isometrix, was carried out across the Oseberg field on the Norwegian Continental Shelf. The potential for broadband measurements, wavefield reconstruction and application in time-lapse settings were investigated.
