Click to download brochure (PDF)FrOG Tech has released two studies in Norway, covering the Norwegian Sea and Western Barents Sea areas. Both studies are based on FrOG Tech’s “bottom-up” approach for basin evaluation and have been developed from the systematic calibration, integration and interpretation of Norske Shell’s regional data-sets and non-exclusive surveys in the areas, combined with publically available data. The studies were originally commissioned by Norske Shell, but are now available to other companies. 

The SEEBASE™ model provides a detailed view of basin elements, including: 

Møre Basin, Vøring Basin, Vigrid Syncline, Gjallar Ridge, Treana Basin, Nordland Ridge, Halten Terrace, Vigra High, Ona High, Nyk High, amongst others in the Norwegian Sea

Bjørnøya Basin, Trømsø Basin, Sørvestsnaget Basin, Hammerfest Basin, Nordkapp basins, Stappen High, Loppa High, Norsel High, Fdgeøya Platform, amongst others in the Western Barents Sea.

Terrane properties are described for the mapped basement terranes, including:

  • Gjallar Terrane, Møre Shetland Terrane, Vøring Terrane, Hebrides Terrane, Utgard Terrane, Trøndelag Platform, Fennoscandian Shield, amongst others in the Norwegian Sea, and
  • Bjørnøya Terrane, Svalbard Terranes, Nordkapp Terrane, Utgard Terrane, amongst others in the Western Barents Sea.
Structural history is unravelled and comprehensive fault maps are included which highlight the importance of some of the major structures in the area, including the Jan Mayen Transform Zone, the Hornsfund Fault Complex, etc. Tectonic events are described from the Caledonian Orogeny to recent. 

Each of the studies includes:

  • A detailed SEEBASE™ basement depth model (Structurally Enhanced view of Economic BASEment) based on the integration of gravity and magnetic data (incl. Depth modelling) with information from wells, seismic data and cross-sections,
  • Maps of basement structures and basement terranes,
  • A regionally consistent structural model showing the evolution of the areas throughout different tectonic events:
    • Maps of active faults and fault kinematics for each event,
    • Comprehensive discussions of the plate tectonic setting for each event, based on plate reconstruction models,
    • Discussions on the implications of basement terrane properties on the structural style in different areas,
  • Maps for Moho depth, crustal thickness, basement thickness, crustal extension, sediment thickness,
  • Petroleum systems:
    • Reservoir potential: 
      • identification of areas with (high) risks for poor reservoirs,
      • highlighting paleo-sediment transport pathways and areas with possible for good reservoirs,
    • Source potential:
      • Discussion of source rock distribution and maturity in different basins,
    • Distribution of volcanic features,
  • Models for basement controlled fluid focusing,
  • An extensive set of magnetic models in both areas and gravity models in the Norwegian Sea,
  • Public domain data-sets including processed and updated gravity and magnetic data for the areas,
  • An ArcGIS project with all the interpretive layers, the processed potential field data-sets and data-sets from the public domain.

In summary, the studies provide a unique regional tectonostratigraphic framework for offshore Norway that can be used as a framework for observations on petroleum systems and plays, or that can provide regionally constrained boundary conditions for input in basin modelling studies.
