      Nourani, Meysam; Tichelkamp, Thomas; Hosseinzade Khanamiri, Hamid; Johansen, Trine; Hov, Ingrid Karlsen; Gawel, Bartlomiej; Torsæter, Ole; Øye, Gisle (Peer reviewed; Journal article, 2020)
      Experimental results of dynamic contact angle measurements of low salinity brine and combined low salinity water and surfactant flooding (LSW–SF) on silica surface are presented in this study. Dynamic contact angle experiments ...
    • Effect of CO2 tax on energy use in oil production: waterflooding optimization under different emission costs 

      Angga, I Gusti Agung Gede; Bellout, Mathias; Kristoffersen, Brage Strand; Bergmo, Per Eirik Strand; Slotte, Per Arne; Berg, Carl Fredrik (Peer reviewed; Journal article, 2022)
      Tackling emissions from hydrocarbon production is a necessity because hydrocarbon production will last for a prolonged time. As a popular hydrocarbon production method, waterflooding operation is energy-intensive and ...

    • Lithology classification of whole core CT scans using convolutional neural networks 

      Chawshin, Kurdistan; Berg, Carl Fredrik; Varagnolo, Damiano; Lopez, Olivier (Peer reviewed; Journal article, 2021)
      X-ray computerized tomography (CT) images as digital representations of whole cores can provide valuable information on the composition and internal structure of cores extracted from wells. Incorporation of millimeter-scale ...
    • A predictive model for the wettability of chalk 

      Nourani, Meysam; Schovsbo, Niels Hemmingsen; Jahanbani Ghahfarokhi, Ashkan; Nielsen, Carsten Møller; Sigalas, Lykourgos; Meyer, Aurelien Gabriel; Olsen, Dan; Stemmerik, Lars (Peer reviewed; Journal article, 2020)
      Wettability is usually measured in special core analyses of limited plug samples according to typically costly and time-consuming procedures. For comparative purposes, wettability is considered an index. The two most ...
