Creep and Consolidation in Pierre Shale - Identification of how time-dependent effects are influenced by alteration in pore fluid pH and changes in stress conditions
Lund, Elisabeth; Kleiven, Marta Laukeland (Master thesis, 2016)The Petroleum Safety Authority of Norway (PSA) has now acknowledged the use of shale as an annular barrier for permanent plug and abandonment (PP&A) operations in the oil industry. Shale can exhibit a natural self-sealing ... -
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 ...
