    • On the Effect of CO2 on Seismic and Ultrasonic Properties: A Novel Shale Experiment 

      Rørheim, Stian; Bhuiyan, Mohammad Hossain; Bauer, Andreas; Cerasi, Pierre (Peer reviewed; Journal article, 2021)
      Carbon capture and storage (CCS) by geological sequestration comprises a permeable formation (reservoir) for CO2 storage topped by an impermeable formation (caprock). Time-lapse (4D) seismic is used to map CO2 movement in ...

    • Shale Creep as Leakage Healing Mechanism in CO2 Sequestration 

      Cerasi, Pierre; Lund, Elisabeth; Kleiven, Marta Laukeland; Stroisz, Anna Magdalena; Pradhan, Srutarshi; Kjøller, Claus; Frykman, Peter; Fjær, Erling (Journal article; Peer reviewed, 2017)
      Experiments on shale specimens targeted creep deformation in order to investigate whether this mechanism could be relied upon to close fractures and stop leakage near injection wells. Uniaxial compression tests were conducted ...

    • 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 ...
