OSLO, Norway – PGS has released a newly reprocessed dataset, which includes acreage offered in the Central Viking Graben of the North Sea under the UK’s 32nd licensing round.
PGS19M04VIK is said to be a high-density, AVO-compliant seismic dataset that defines stratigraphy and basin structures.
It covers producing fields in the region such as Beryl, Bruce, Maclure and Nevis, and highlights near-field upside potential and exploration targets.
The dataset also extends onto the East Shetland Platform, defining the basin configuration into the Triassic and imaging the transition to and the structure of the platform.
Known fields range from Triassic-Jurassic structural closures to Eocene injectites in the depocenters. Eocene injectites have been the targets of various successful drilling campaigns, the company added.
There could also be potential in Paleozoic structures at the margin and on the East Shetland Platform.
PGS’ reprocessing of legacy GeoStreamer data involved regeneration of P-UP with 2020 workflows and application of demultiple methods, including the separated wavefield imaging (PGS SWIM).
The company also used PGS FWI, based on reflections and refractions, to create a high-resolution, high-fidelity velocity model.
