    • The effects of uplift and erosion on the petroleum systems in the southwestern Barents Sea: Insights from seismic data and 2D petroleum systems modelling 

      Ktenas, Dimitrios; Nielsen, Jesper Kresten; Henriksen, Erik; Meisingset, Ivar; Schenk, Oliver (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-05)
      In the past three decades, the hydrocarbon prospectivity has been enigmatic in the southwestern Barents Sea as gas discoveries have dominated over oil. However, more recent discoveries indicate oil potential, especially in the Polheim Platform and Hoop Complex areas. Cenozoic uplift and erosion episodes are critical because they control the duration and depth of maximum burial of source rocks and ...

    • Estimation of net apparent erosion in the SW Barents Sea by applying velocity inversion analysis 

      Ktenas, Dimitrios; Meisingset, Ivar; Henriksen, Erik; Nielsen, Jesper Kresten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      The SW Barents Sea was subjected to significant uplift and erosion during the Cenozoic, processes that are believed to have had a significant impact on hydrocarbon maturation and migration in the area. The current study uses compaction of shale- and sand-dominated layers to make a map of net apparent erosion throughout the SW Barents Sea. The map shows regional trends consistent with deep-seated ...

    • Quantification of the magnitude of net erosion in the southwest Barents Sea using sonic velocities and compaction trends in shales and sandstones 

      Ktenas, Dimitrios; Henriksen, Erik; Meisingset, Ivar; Nielsen, Jesper Kresten; Andreassen, Karin (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-19)
      During specific intervals within Mesozoic and Cenozoic times, several areas of the southwestern Barents Sea were subjected to uplift and erosion. Areas with missing shallow stratigraphic interval sections and major erosion can be seen at several places along interpreted regional profiles in the southwestern Barents Sea. A new Normal Compaction Trend (NCT) for two selected shale– and ...
