CO2 Flow, Alteration And Geomechanical Response In Confining Units – An Experimental ApproachGreen Open Access
Skurtveit, Elin; Sundal, Anja; Soldal, Magnus; Sauvin, Guillaume; Bjørnarå, Tore Ingvald (Lecture, 2018)Seal integrity during injection operations is a topic of great interest both within the CO2 storage community, for wastewater injection and traditional reservoir pressure support. The Little Grand Wash fault, central Utah, ... -
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. ... -
Experimental percolation of supercritical CO2 through a caprock
Angeli, Matthieu; Soldal, Magnus; Skurtveit, Elin; Aker, Eyvind (Journal article, 2009)Leakage of CO2 into the atmosphere is the most crucial concern for geological storage of anthropogenic CO2. Leakage routes could develop through existing wells and pipelines, but also by natural migration of CO2 rich ... -
Inferring microseismic source mechanisms and in situ stresses during triaxial deformation of a North-Sea-analogue sandstone
Griffiths, Luke; Dautriat, Jérémie; Rodriguez, Ismael A Vera; Iranpour, Kamran; Sauvin, Guillaume; Park, Joonsang; Sarout, Joel; Soldal, Magnus; Grande, Lars; Oye, Volker; Dewhurst, David; Mondol, MD Nazmul Haque; Choi, Jung Chan (Peer reviewed; Journal article, 2019)Monitoring microseismic activity provides a window through which to observe reservoir deformation during hydrocarbon and geothermal energy production, or CO2 injection and storage. Specifically, microseismic monitoring may ... -
Influence of CO2 on rock physics properties in typical reservoir rock: A CO2 flooding experiment of brine saturated sandstone in a CT-scanner
Alemu, Binyam Lema; Aker, Eyvind; Soldal, Magnus; Johnsen, Øistein; Aagaard, Per (Journal article, 2011)Laboratory core flooding experiment was run to investigate the joint use of electrical resistivity, ultrasonic velocities and 3D images of fluid distribution to improve current understanding of CO2 and brine behaviour ...
