• 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 ...
    • Experimental Investigation of the Influence of Injection Pressure and Clay Smear on Fault Reactivation for Co2 Storage 

      Griffiths, Luke; Park, Joonsang; Cerasi, Pierre; Edvardsen, Laura; Wüstefeld, Andreas (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)
      Induced microseismicity from subsurface engineering projects such as geothermal heat exploitation and CO2 storage can be a show-stopper and halt the development of a site. While microseismicity correlates with fluid injection ...
    • Impact of Innovations from the Norwegian CCS Research Centre (NCCS) 

      Tangen, Grethe; Kim, Inna; Brunsvold, Amy; Mølnvik, Mona J.; Vevelstad, Solrun J.; Skurtveit, Elin; Roussanaly, Simon; Munkejord, Svend T.; Cerasi, Pierre; Eliasson, Peder (SINTEF Proceedings;7, Chapter; Research report; Conference object, 2021)
      We have evaluated the potential impact of the research and innovation performed in the Norwegian CCS Research Centre (NCCS). In this context, impact was evaluated along several axes. Examples include reduced emissions, ...
    • 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 ...
    • Monitoring of Co2 Well Plug Integrity. Electrical Response of Cement/CNF Sensor to Mechanical Load, Water Saturation and Carbonation 

      Gawel, Kamila; Wenner, Sigurd; Taghipour, Ali; Szewczyk, Dawid; Edvardsen, Laura; Brocks, Anette; Hagen, Anna Stroisz; Gawel, Bartlomiej; Bjørge, Ruben; Ghaderi, Amir; Cerasi, Pierre; Malin, Torsæter (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)
      CO2 storage wells will eventually need to be permanently plugged and abandoned. Subsidence, fault/fracture reactivation or chemical degradation can all adversely affect well plug integrity leading to CO2 leakages. Thus, ...
    • 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 (Peer reviewed; Journal article, 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 ...
    • Simulation of stress hysteresis effect on permeability increase risk along a fault 

      Rongved, Mats; Cerasi, Pierre (Journal article; Peer reviewed, 2019)
      CO2 sequestration projects will in the coming years include both aquifer and depleted oil and gas field sites, with different stress paths and history. Stress changes and stress concentration effects on faults will have ...
