• Closing of Micro-cavities in Well Cement upon Exposure to CO2 Brine 

      Chavez Panduro, Elvia Anabela; Torsæter, Malin; Gawel, Kamila; Bjørge, Ruben; Gibaud, Alain; Yang, Yi; Sørensen, Henning; Frykman, Peter; Kjøller, Claus; Breiby, Dag Werner (Journal article; Peer reviewed, 2017)
      Long-lasting cement plugging of wells is crucial for successful CO2 storage in underground reservoirs. It requires a profoundly improved understanding of the behavior of fractured cement under realistic subsurface conditions ...
    • 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 ...
    • Nanoscale imaging of shale fragments with coherent X-ray diffraction 

      Chattopadhyay, Basab; Madathiparambil, Aldritt Scaria; Mürer, Fredrik Kristoffer; Cerasi, Pierre; Chushkin, Yuriy; Zontone, Federico; Gibaud, Alain; Breiby, Dag Werner (Journal article; Peer reviewed, 2020)
      Despite the abundance of shales in the Earth’s crust and their industrial and environmental importance, their microscale physical properties are poorly understood, owing to the presence of many structurally related mineral ...
    • 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, ...
