Ireland IRE-16

Porcupine Basin

CGG has acquired 10,500 km² of 3D and ~2,000 km of 2D long-offset broadband data in the Porcupine Basin, which has been processed through advanced pre-stack depth imaging, including Full-Waveform Inversion (FWI) velocity modeling. Final data for the Cairenne and Galway surveys is available now.

The data has been processed through Ghost Wavefield Elimination (GWE), advanced demultiple and high-resolution velocity modeling, through Multi-Layer Tomography (Tomo ML) and FWI, to provide broadband data with minimal noise contamination.

The enhanced low frequencies deliver unprecedented deep imaging for this area, with enhanced definition of the prospective deep Jurassic fault blocks and overlying Creataceous-Tertiary wedges.

In addition, the high resolution in the shallow data provides clear, highly-detailed images of channels and other features which are also highlighted by the FWI velocity model.

These state-of-the-art seismic images complement our existing extensive GeoSpec Irish Legacy Database to enhance understanding of this highly prospective area.
