    • HyGreGel: A new class of gel systems for water diversion by in-depth reservoir placement 

      Najafiazar, Bahador (Doctoral theses at NTNU;2019:336, Doctoral thesis, 2019)
      High water production is typically a major problem late in the life cycle of a water flooded hydrocarbon reservoir. Reservoir heterogeneity plays a significant role in creating this problem. An example is highly permeable ...

    • Identification of Nanocellulose Retention Characteristics in Porous Media 

      Aadland, Reidun Cecilie Grønfur; Dziuba, Carter Jordan; Heggset, Ellinor Bævre; Syverud, Kristin; Torsæter, Ole; Holt, Torleif; Gates, Ian D.; Bryant, Steven (Journal article; Peer reviewed, 2018)
      The application of nanotechnology to the petroleum industry has sparked recent interest in increasing oil recovery, while reducing environmental impact. Nanocellulose is an emerging nanoparticle that is derived from trees ...

    • Large Scale Tertiary CO2 EOR in Mature Water Flooded Norwegian Oil Fields 

      Lindeberg, Erik Gøsta Brun; Grimstad, Alv-Arne; Bergmo, Per Eirik Strand; Wessel-Berg, Dag; Torsæter, Malin; Holt, Torleif (Journal article; Peer reviewed, 2017)
      A technical-economical model for a large-scale infrastructure combining CO2 EOR and aquifer storage has been used to construct a scenario including 23 Norwegian Continental Shelf oil fields that have been identified as ...

    • Polymer Gels Made with Functionalized Organo-Silica Nanomaterials for Conformance Control 

      Najafiazar, Bahador; Wessel-Berg, Dag; Bergmo, Per Eirik Strand; Simon, Christian; Yang, Juan; Torsæter, Ole; Holt, Torleif (Journal article; Peer reviewed, 2019)
      Deep placement of gel in waterflooded hydrocarbon reservoirs may block channels with high water flow and may divert the water into other parts of the reservoir, resulting in higher oil production. In order to get the gel ...
