oa 2D Marine Seismic Acquisition for Sub-salt Objectives in the Red Sea

SAUDI ARAMCO recently acquired a very large regional 2D reconnaissance marine seismic program in the Red Sea. The objectives of the project were to identify and map potential leads both above and below salt bodies in the Red Sea basin. Streamer length and depth were tested for their impact on low frequency data recovery and imaging of deep objectives. Prestack depth migration results show improvement in deep imaging as the maximum offset is increased from 7200 meters to 10,330 meters. The greatest improvement in depth image quality occurs when offsets of up to 9200 meters are included. New solid streamer technology proved valuable for acquiring the long offsets required by this project while maintaining continuous operations.
