An Efficency-driven Implementation of Multimeasurement Streamer Technology for High-resolution Imaging of Exploration Targets in the Flemish Pass

This paper evaluates the proposition that a multimeasurement system that supports subsequent reconstruction of virtual cables for denser crossline sampling yields benefits in exploration settings where high-resolution data are a necessity to identify and evaluate prospects; benefits include reduced time and maximizing use of the 3D deghosted and reconstructed data sets produced real-time onboard for a largescale acquisition program. The experiment highlights the benefits of using 12.5-m sampling in the crossline direction versus 25 m for final migrated seismic sections, spectral improvements, and geologic attributes from an interpretation system. The results achieved leverages multimeasurement wavefield reconstruction to yield solutions best suited to resolve the geological complexity of this region. It demonstrates that, utilizing this technology and approach, it is possible to very efficiently acquire data with a development type and level of data density (including the crossline component) in an exploration environment.
