      Edvardsen, Laura; Emmel, Benjamin Udo; Bhuiyan, Mohammad Hossain; Wenner, Sigurd; Gawel, Kamila; Torsæter, Malin (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)
      In this paper we ask the question whether or not electrochemically enhanced deposition of minerals can be utilized to repair leakage paths existing in cement plugs in wells. Electrical polarization of two electrodes may ...
    • 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, ...
