OSLO, Norway – PGS has issued a new ultra-high-density high-resolution dataset over the Hammerfest basin in the Norwegian Barents Sea.
The data, which includes coverage of open acreage, is said to resolve the challenges of exploration in this geologically complex area through a combination of streamer setup and advanced imaging technologies. Altogether it extends from the Finnmark Platform in the southwest into the Hammerfest basin in the northeast. Some of the main findings include:
Deep marine sand deposits along the southern flank of the Hammerfest basin showing variable seismic amplitude anomalies
The combination of densely recorded data and imaging techniques delivering a high-resolution seismic image: at top Kolmule the tuning thickness is reduced down to around 8 m (26.2 ft)
Clear identification of seismic amplitude anomalies within various stratigraphic units
Structural traps in the Realgrunnen sandstones and Triassic fluvial channel deposits in the Snadd and Kobbe formations.
PGS’ planned 2020 survey extension includes open acreage in the Barents Sea, an area thought to hold half Norway’s undiscovered hydrocarbons resources.
According to the company, target areas for hydrocarbon plays in the southwestern Barents Sea are the shallow Kapp Toscana Group sandstones and deeper Mid-Triassic Kobbe Formation sandstones, and potentially karstified, Carboniferous/Permian carbonates.
