Coil Shooting Acquisition – An Efficient Method For Subsalt Exploration

Exploration and development of offshore deep water subsalt reservoirs could be very costly due to the drilling challenges. Seismic image of the reservoir is the key factor for generating the reservoir model that is used for drilling. In the last four years wide-azimuth (WAZ) towed-streamer acquisition has been established as a successful technology for exploration and development of the complex subsalt structures in the Gulf of Mexico. In this paper we present coil shooting acquisition, a novel method to acquire WAZ surveys using circular geometry.
