    • 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 ...

    • 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 ...

    • 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 ...

    • Orientational mapping of minerals in Pierre shale using X-ray diffraction tensor tomography 

      Mürer, Fredrik Kristoffer; Madathiparambil, Aldritt Scaria; Tekseth, Kim Robert Bjørk; Di Michiel, Marco; Cerasi, Pierre; Chattopadhyay, Basab; Breiby, Dag Werner (Peer reviewed; Journal article, 2021)
      Shales have a complex mineralogy with structural features spanning several length scales, making them notoriously difficult to fully understand. Conventional attenuation-based X-ray computed tomography (CT) measures density ...

    • 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 ...

    • Workflow for Sensitivity Analysis and Decision Making on the Lower Limit of the Mud-Weight Window in an Overpressured Formation 

      Paglia, Jacopo; Eidsvik, Jo; Cerasi, Pierre (Peer reviewed; Journal article, 2020)
      When drilling a well it is important to choose a reasonable mud density to ensure safe operations. This is not a trivial task because a balanced mud-weight has a complex relation to the uncertain formation conditions and ...
