Moray Firth - UK - 2018

PGS18001MOF 3D GeoStreamer

New Moray Firth data ideal for evaluation of UKCS Frontier Areas
Website Map for Survey PGS18001MOF
Poorly understood reservoirs and petroleum systems in the Moray Firth revealed by high-quality GeoStreamer 3D seismic data. Increased resolution and advanced imaging results will aid understanding and optimize exploration opportunities and discoveries.
Play types in this immature area of the CNS derived from the Kimmeridge Clay source. Upper Jurassic and Lower Cretaceous sandstone reservoirs with structural and stratigraphic traps. Up dip migration through sandstones and 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.
