Optimization of Swell Noise Specifications as Part of Survey Design

A34 OPTIMIZATION OF SWELL NOISE SPECIFICATIONS AS PART OF SURVEY DESIGN Abstract 1 A swell noise simulation was carried out during the survey design of a 3D acquisition planned by Total in the Norwegian Sea. The motivation for this study was that reprocessing of previous 2D data in the area had shown great sensitivity to swell noise of some programs of the forecasted 3D processing sequence (especially shot interpolation and pre-stack migration in time or in depth). Swell noise contaminated records were simulated by adding real noise records to shot points recorded in quiet conditions. The full processing sequences (Pre-Stack
