Full-Azimuth Towed-Streamer Seismic: An Exploration Tool for Pre-Salt Hydrocarbon Exploration Offshore Brazil

Summary With a string of recent discoveries in the pre-salt areas in deep-water offshore Brazil, this hydrocarbon province has proven to be of global importance. The pre-salt reservoirs, however, present many challenges for exploration. In this paper, we describe the acquisition and processing of a fullazimuth towed-streamer seismic survey designed for presalt exploration offshore Brazil. We show that this solution overcomes many of the pre-salt exploration challenges to prov ide high-quality reservoir information in an efficient manner.
