Survey Design for Ultra-High Resolution 3D Seismic

This technical report discusses survey design considerations for ultra-high resolution 3D seismic site characterization surveys, particularly in the context of offshore wind farm site characterization. It outlines traditional 3D marine streamer seismic acquisition methods and their limitations, particularly for shallow water and shallow targets. The report describes advancements in acquisition configurations, specifically the use of wide-tow multi-source configurations, which improve near-offset coverage and spatial sampling. The analysis includes comparisons of different source deployment modes, such as Narrow Dual Source, Narrow Triple Source, and Wide-Tow Triple Source, detailing their respective performance in terms of crossline gaps and near-offset data quality. The report emphasizes the importance of tailored seismic solutions based on local geological conditions and the specific objectives of the surveys. It also presents various configurations designed for different water depths and discusses their efficiency and trace density, contributing to improved imaging and data quality for seismic surveys.
