• CO2 mobility reduction using foam stabilized by CO2- and water-soluble surfactants 

      Føyen, Tore Lyngås; Alcorn, Zachary Paul; Fernø, Martin; Barrabino, Albert; Holt, Torleif (Peer reviewed; Journal article, 2020)
      Foam can reduce CO2 mobility to improve the sweep efficiency during injection into subsurface geological formations for CO2 storage and enhanced oil recovery. However, CO2 foams are thermodynamically unstable, so they must ...
    • An Evaluation of Graphene Oxides as Possible Foam Stabilizing Agents for CO2 Based Enhanced Oil Recovery 

      Barrabino, Albert; Holt, Torleif; Lindeberg, Erik (Peer reviewed; Journal article, 2018)
      Graphene oxide, nanographene oxide and partially reduced graphene oxide have been studied as possible foam stabilizing agents for CO2 based enhanced oil recovery. Graphene oxide was able to stabilize CO2/synthetic sea water ...
    • First Approach to Measure Interfacial Rheology at High-Pressure Conditions by the Oscillating Drop Technique 

      Barrabino, Albert; Holt, Torleif; Bjørkvik, Bård Johan Arnt; Lindeberg, Erik Gøsta Brun (Peer reviewed; Journal article, 2021)
      An oscillating drop rheometer capable of operating under conditions of high pressure and high temperature has been built. The oscillating drop mechanism was able to support pressures as high as 1300 bar and successfully ...
    • Increased CO2 storage capacity using CO2 -foam 

      Føyen, Tore Lyngås; Brattekås, Bergit; Fernø, Martin; Barrabino, Albert; Holt, Torleif (Peer reviewed; Journal article, 2020)
      Reduction of the CO2 mobility is beneficial during subsurface sequestration of anthropogenic CO2 in saline aquifers and hydrocarbon reservoirs by mitigating flow instabilities leading to early gas breakthrough and poor ...
    • Partitioning of non-ionic surfactants between CO2 and brine 

      Barrabino, Albert; Holt, Torleif; Lindeberg, Erik Gøsta Brun (Peer reviewed; Journal article, 2020)
      The partitioning of non-ionic surfactants in a CO2/synthetic brine system was studied for a selection of surfactants at reservoir conditions for CO2 enhanced oil recovery and aquifer storage. Alkyl and alkylphenol ethoxylates ...
