Abstract

This paper presents a seismic acquisition case study in the Angolan deep offshore where coil shooting technique has been designed and implemented to deliver a high fold and full azimuth coverage around a sub-salt target area. During the acquisition phase, near real time 3D modeling was run on-board the seismic vessel as a part of the acquisition QC to assess the achieved coil coverage. The seismic survey was safely completed in three weeks with no incidents recorded. High production rates were achieved thanks to the continuous shooting allowed by the Coil technique. Preliminary fast track processing results of Coil data show encouraging imaging enhancement when compared to the conventional narrow azimuth data that was acquired in the same area and period.
