• Avoiding Damage of CO2 Injection Wells Caused by Temperature Variations 

      Torsæter, Malin; Todorovic, Jelena; Lavrov, Alexandre; Gawel, Kamila; Lund, Halvor; Roy, Pratanu; Carroll, Susan (Journal article; Peer reviewed, 2017)
      Well integrity is a prerequisite for safe geological storage of CO2. Both active and abandoned wells are man-made channels between the storage reservoir and the atmosphere that can become leakage paths over time. The CO2 ...
    • Carbonation of silica cement at high-temperature well conditions 

      Bjørge, Ruben; Gawel, Kamila; Chavez Panduro, Elvia Anabela; Torsæter, Malin (Journal article; Peer reviewed, 2019)
    • Computed X-ray Tomography Study of Carbonate Precipitation in Large Portland Cement Pores 

      Chavez Panduro, Elvia Anabela; Torsæter, Malin; Gawel, Kamila; Bjørge, Ruben; Gibaud, Alain; Bonnin, Anne; Schlepütz, Christian M.; Breiby, Dag Werner (Journal article; Peer reviewed, 2019)
      Cement degradation caused by CO2 exposure is an increasingly important environmental challenge that must be understood, for example, if former oil reservoirs are to be used for CO2 storage. When exposed to CO2-saturated ...
    • Effects of Water Content and Temperature on Bulk Resistivity of Hybrid Cement/Carbon Nanofiber Composites 

      Gawel, Kamila; Taghipour, Ali; Bjørge, Ruben; Wenner, Sigurd; Gawel, Bartlomiej; Ghaderi, Amir; Cerasi, Pierre (Peer reviewed; Journal article, 2020)
      Cement nanocomposites with carbon nanofibers (CNFs) are electrically conductive and sensitive to mechanical loads. These features make them useful for sensing applications. The conductive and load sensing properties are ...
    • Electrochemical enhancement and inhibition of calcium carbonate deposition 

      Edvardsen, Laura; Gawel, Kamila; Wenner, Sigurd; Gawel, Bartlomiej; Torsæter, Malin (Peer reviewed; Journal article, 2020)
      Calcium carbonate is by far the most widespread scaling material. Its deposition in pipes and flowlines has been a long-standing problem for many industries. Hence, a lot of research is devoted to scale inhibition. One of ...
    • Micro- and macroscale consequences of interactions between CO2 and shale rocks 

      Bhuiyan, Mohammad Hossain; Agofack, Nicolaine; Gawel, Kamila; Cerasi, Pierre (Peer reviewed; Journal article, 2020)
      In carbon storage activities, and in shale oil and gas extraction (SOGE) with carbon dioxide (CO2) stimulation fluid, CO2 comes into contact with shale rock and its pore fluid. As a reactive fluid, the injected CO2 displays ...
    • Real Time 3D Observations of Portland Cement Carbonation at CO2 Storage Conditions 

      Chavez Panduro, Elvia Anabela; Cordonnier, Benoit; Gawel, Kamila; Børve, Ingrid; Iyer, Jaisree; Carroll, Susan; Michels, Leander; Rogowska, Melania; McBeck, Jessica Ann; Sørensen, Henning; Walsh, Stuart; Renard, Francois; Gibaud, Alain; Torsæter, Malin; Breiby, Dag Werner (Peer reviewed; Journal article, 2020)
      Depleted oil reservoirs are considered a viable solution to the global challenge of CO2 storage. A key concern is whether the wells can be suitably sealed with cement to hinder the escape of CO2. Under reservoir conditions, ...

    • Salt clogging during supercritical CO2 injection into a downscaled borehole model 

      Berntsen, Andreas Nicolas; Todorovic, Jelena; Raphaug, Martin Hagen; Torsæter, Malin; Chavez Panduro, Elvia Anabela; Gawel, Kamila (Journal article; Peer reviewed, 2019)
      Injection of CO2 into saline storage aquifers is often accompanied by drying of the formation water and salt precipitation. Subsequent salt clogging of a well bore and the near wellbore rock matrix may lead to injectivity ...
