Effect of Field Caprock Shale Exposure to CO2 on Its Mechanical Properties—A Comparison of Experimental Techniques
Cerasi, Pierre; Duda, Marcin; Edvardsen, Laura; Agofack, Nicolaine; Bhuiyan, Mohammad Hossain (Peer reviewed; Journal article, 2022)Laboratory tests were performed on the Draupne shale formation, which may serve as a seal over CO2 storage sites. Different techniques were used to assess the integrity and mechanical properties of the shale, with the main ... -
Mechanical response of cement and shale admixtures under cyclic triaxial loading monitored by in-situ synchrotron micro-computed tomography
Madathiparambil, Aldritt Scaria; Mirzaei, Fazel; Tekseth, Kim Robert Bjørk; Cordonnier, Benoit; Agofack, Nicolaine; Cerasi, Pierre; Renard, Francois; Chattopadhyay, Basab; Breiby, Dag Werner (Peer reviewed; Journal article, 2024)Understanding the mechanical behaviour of natural soils as mixed with cement for stabilization is crucial for civil engineering developments. The response of cement-soil admixtures when subjected to cyclic loads is a largely ... -
Micro- and macroscale consequences of interactions between CO2 and shale rocks
Bhuiyan, Mohammad Hossain; Agofack, Nicolaine; Gawel, Kamila; Cerasi, Pierre (Peer reviewed; Journal article, 2020)In carbon storage activities, and in shale oil and gas extraction (SOGE) with carbon dioxide (CO2) stimulation fluid, CO2 comes into contact with shale rock and its pore fluid. As a reactive fluid, the injected CO2 displays ... -
Thermo‑Poromechanical Properties of Pierre II Shale
Agofack, Nicolaine; Cerasi, Pierre; Sønstebø, Eyvind Frode; Stenebråten, Jørn (Peer reviewed; Journal article, 2022)During the injection of carbon dioxide (CO2) for CO2 capture and storage (CCS) operations, the near-well (including casing, cement, and rock around it) can undergo several thermal loadings. These loadings can significantly ...
