Improving high-resolution imaging

Enhanced amplitude fidelity and thin-bed resolution were the key processing objectives in the reprocessing sequence. The updated workflow, optimized for broadband, was a 3D prestack full-waveform inversion (FWI), which produced a high-resolution velocity model to reduce the effects of shallow channels and near-sea-bottom uncertainties. Current depth imaging, with support of the latest multiple attenuation techniques, focused the subchalk reflections and enhanced fault resolution in the target areas.

The West Wick 3D reprocessing presents a unique opportunity to map the behavior and distribution of thin sands with accuracy.
