PGS’ Hammerfest Basin ultra-high-density high-resolution dataset is available and will be extended in 2020. The data includes open acreage, and gives insights into a complex area in the Barents Sea through a combination of streamer set-up and advanced imaging technologies, said PGS.
Key features revealed with this dataset that extends from the Finnmark Platform in the southwest into the Hammerfest Basin in the northeast include deep marine sand deposits along the southern flank of the Hammerfest Basin showing variable seismic amplitude anomalies.
At Top Kolmule the tuning thickness is reduced down to approximately 8 m. Seismic amplitude anomalies within various stratigraphic units are clearly identified. Structural traps in the Realgrunnen sandstones and Triassic fluvial channel deposits in the Snadd and Kobbe formation are shown.
An innovative acquisition configuration was designed as the best solution to resolve mixed depth targets in the Barents Sea.
PGS’ planned 2020 survey extension includes open acreage in the Barents Sea and the overall area accounts for around half of the undiscovered resources on the NCS, according to the Norwegian Petroleum Directorate.
Key target areas for hydrocarbon plays in the southwestern Barents Sea are the shallow Kapp Toscana Group sandstones, and deeper, middle Triassic Kobbe Formation sandstones and potentially karstified Carboniferous/Permian carbonates.
‘Proven discoveries made in both geological regimes show the great hydrocarbon potential of this area, but a key challenge in producing an accurate image of the subsurface is creating a reliable velocity model that accounts for the area’s complex geological regime,’ said PGS.
