    • Depositional environments and source rock potential of some Upper Palaeozoic (Devonian) coals on Bjørnøya, Western Barents shelf 

      Janocha, Julian; Wesenlund, Fredrik; Thießen, Olaf; Grundvåg, Sten-Andreas; Koehl, Jean-Baptiste Philippe; Johannessen, Erik P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-27)
      Upper Palaeozoic strata are potential sources for hydrocarbon plays on the Norwegian Barents Shelf. The island of Bjørnøya (Bear Island) is located on the western margin of the Barents Shelf and represents an exposed part of the Stappen High, which makes it an excellent location to investigate the source rock potential of this succession. Here, we investigate the organic geochemical composition and ...

    • Linking facies variations, organic carbon richness and bulk bitumen content – A case study of the organic-rich Middle Triassic shales from eastern Svalbard 

      Wesenlund, Fredrik; Grundvåg, Sten-Andreas; Engelschiøn, Victoria Sjøholt; Thießen, Olaf; Pedersen, Jon Halvard (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-03)
      The organic-rich shales of the Middle Triassic Botneheia Formation in Svalbard and its correlative units offshore are considered important source rock intervals for oil and gas generation in the Norwegian Barents Shelf region. Detailed investigation of these intervals is essential to better understand the intra source rock variations and thus to improve exploration models. As source rocks are rarely ...
