Experimental and analytical assessment of Draupne shale seal integrity for CO2 storage sites
Soldal, Magnus; Skurtveit, Elin; Bohloli, Bahman; Wilkinson, Heidi; Choi, Jung Chan; Griffiths, Luke; Smith, Halvard (Lecture, 2019)Carbon dioxide (CO2) capture and storage is one of the most important measures to reduce the atmospheric concentration of CO2. To ensure safe storage, operations must be conducted in way that respects operational limitations. ... -
Frictional Properties and Seismogenic Potential of Caprock Shales
Bohloli, Bahman; Soldal, Magnus; Smith, Halvard; Skurtveit, Elin; Choi, Jung Chan; Sauvin, Guillaume (Peer reviewed; Journal article, 2020)Fractures and faults are critical elements affecting the geomechanical integrity of CO2 storage sites. In particular, the slip of fractures and faults may affect reservoir integrity and increase potential for breach, may ... -
