Moray Firth - UK - 2018

PGS18002MOF 3D GeoStreamer® (In Processing)

New Moray Firth data for evaluation of UKCS 31st round blocks
Website Map for Survey PGS18002MOF
The Inner Moray Firth region has had, until now, a lack of modern 3D seismic data. This new high-quality 3D seismic will enable geological models to be updated for enhanced prospectivity evaluation in the UKCS 31st Round.
This overlooked area has Lower-Middle Devonian and Kimmeridge Clay source rock potential. Reservoir intervals can be found in Permian to Upper Jurassic and Lower Cretaceous sandstones, with both structural and stratigraphic trapping. Updip migration can occur through sandstones and via major faults.
Multi-sensor GeoStreamer acquisition with triple source has provided high-density data. State-of-the-art processing technology includes Complete Wavefield Imaging (CWI). Shallow and deep targets will be imaged using anisotropic TTI Kirchhoff PSDM. Final PSDM available by September 2019.
