Closing of Micro-cavities in Well Cement upon Exposure to CO2 Brine
Chavez Panduro, Elvia Anabela; Torsæter, Malin; Gawel, Kamila; Bjørge, Ruben; Gibaud, Alain; Yang, Yi; Sørensen, Henning; Frykman, Peter; Kjøller, Claus; Breiby, Dag Werner (Journal article; Peer reviewed, 2017)Long-lasting cement plugging of wells is crucial for successful CO2 storage in underground reservoirs. It requires a profoundly improved understanding of the behavior of fractured cement under realistic subsurface conditions ... -
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 ...
