Full-Azimuth Marine Acquisition Using the Coil Shooting Technique

Abstract

SUMMARY Wide-azimuth (WAZ) marine acquisition using towed-streamer technology has seen dramatic growth in recent years: mainly in the Gulf of Mexico. To date, the WAZ technique typically requires the use of multiple vessels. We report here on Coil Shooting*; a method of collecting full-azimuth (FAZ) data using one vessel. In this paper, we discuss survey designs for coil acquisition focusing on survey efficiency. We also show results of extended field trials and review data processing challenges such as noise removal and multiple attenuation.
