Presurvey planning of marine 3D seismic surveys has evolved to be a rigorous pursuit of 1D, 2D, and 3D elastic modeling exercises complemented where appropriate with the reprocessing of available 2D and 3D field data. It is often the case that the resulting recommendations for acquisition parameterization have expensive implications, and a significant emphasis must be placed upon the credibility of the modeling results.

I demonstrate with several multistreamer case studies that presurvey planning studies can be applied with great accuracy. Emphasis is on the quantification of the crossline acquisition footprint, the quantification of long-offset requirements for both AVO and...
