Moray Firth - UK - 2018

PGS18003MOF 3D GeoStreamer

New Moray Firth data ideal for evaluation of UKCS Frontier Areas
Website Map for Survey PGS18003MOF
The Inner Moray Firth region has lacked modern 3D seismic data. This new high-quality 3D seismic will enable the geological models to be updated for prospectivity evaluation.
Overlooked area in the CNS with Lower to Middle Devonian source rock potential in addition to Kimmeridge Clay. Permian to Upper Jurassic and Lower Cretaceous sandstones reservoir levels with structural and stratigraphic traps, up dip migration through sandstones, major faults with effective seals.
Multisensor GeoStreamer acquisition with triple source provides high-density data, processed using state-of-the-art technology, including Complete Wavefield Imaging (CWI). Shallow and deep targets have been imaged using anisotropic TTI Kirchhoff PSDM. Final PSDM data is available.
