    • Contact Angles in Two-Phase Flow Images 

      Hosseinzade Khanamiri, Hamid; Slotte, Per Arne; Berg, Carl Fredrik (Peer reviewed; Journal article, 2020)
      In this work, we calculate contact angles in X-ray tomography images of two-phase flow in order to investigate the wettability. Triangulated surfaces, generated using the images, are smoothed to calculate the contact angles. ...

    • Dynamic wettability alteration for combined low salinity brine injection and surfactant flooding on silica surface 

      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 ...

    • Fluid Topology in Pore Scale Two‐Phase Flow Imaged by Synchrotron X‐ray Microtomography 

      Hosseinzade Khanamiri, Hamid; Torsæter, Ole (Journal article; Peer reviewed, 2018)
      A flow experiment including drainage and imbibition by water and surfactant was performed on a water‐wet Berea sandstone. The three‐dimensional (3‐D) pore scale changes of the fluid configuration were captured under flow ...

    • Geometrically derived efficiency of slow immiscible displacement in porous media 

      Berg, Carl Fredrik; Slotte, Per Arne; Hosseinzade Khanamiri, Hamid (Peer reviewed; Journal article, 2020)
      The efficiency of a displacement is the fraction of applied work over the change in free energy. This displacement efficiency is essential for linking wettability to applied work during displacement processes. We quantify ...

    • Predicting Resistivity and Permeability of Porous Media Using Minkowski Functionals 

      Slotte, Per Arne; Berg, Carl Fredrik; Hosseinzade Khanamiri, Hamid (Journal article; Peer reviewed, 2019)
      Permeability and formation factor are important properties of a porous medium that only depend on pore space geometry, and it has been proposed that these transport properties may be predicted in terms of a set of geometric ...
