    • The impact of saturation on seismic dispersion in shales — Laboratory measurements 

      Szewczyk, Dawid; Holt, Rune Martin; Bauer, Andreas (Peer reviewed; Journal article, 2018)
      Previous studies found a significant increase of acoustic velocities between seismic and ultrasonic frequencies (seismic dispersion) for shales, which would have to be taken into account when comparing seismic or sonic ...

    • 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, ...

    • Self-Sensing Well Cement 

      Gawel, Kamila; Szewczyk, Dawid; Cerasi, Pierre (Peer reviewed; Journal article, 2021)
      Chemical reactions with reservoir fluids and geology related in-situ stress changes may cause damages to cement sealing material in plugged and abandoned oil, gas and CO2 wells. To avoid leakages, a legitimate monitoring ...
