Navigate shallow waters with DUG MP-FWI Imaging

Shallow-water environments are notoriously challenging for conventional processing workflows due to the presence of strong, short-period multiples that obscure primary signal. Limitations in common multiple-prediction schemes often result in derived…

Subsalt success with DUG MP-FWI Imaging

Resolving illumination issues caused by complex salt bodies has been a persistent geophysical challenge. DUG MP-FWI Imaging uses all parts of the scattered wavefield to reconstruct the reflectivity and kinematic…

DUG MP-FWI Imaging enables new discoveries with old data

DUG MP-FWI Imaging is not just a solution for modern acquisition. It’s not just for high-density, full-azimuth, long-offset data. While modern acquisition has many benefits, significant uplift can still be…

DUG MP-FWI Imaging: Field data to fluid prediction

Quantitative interpretation requires true amplitudes and high signal-to-noise ratio. DUG MP-FWI Imaging delivers superior pre-stack reflectivity outputs for both AVA analysis, and, elastic rock property and fluid prediction—directly from field…

FWI Imaging under complex geological anomalies

Offshore Brazil: Reducing risk with regional 3D reprocessing

Coloured Pre-Salt Isopach Map relating mature Lagoa Feia source rock presence with Base of Salt structure contours displaying the fetch and hydrocarbon migration pathways to the pre-salt lead. Interpreted seismic…

Maximising the potential of seismic expressions

Spectral decomposition methods are widely used to highlight geological features according to their frequency content. However, the frequencies characterising the targeted event might vary spatially, which complicates their extraction as…
