An analytical plane-strain solution for surface uplift due to pressurized reservoirs
Wangen, Magnus; Halvorsen, Gotskalk; Gasda, Sarah Eileen; Bjørnarå, Tore Ingvald (Peer reviewed; Journal article, 2018)In this paper, we present an analytical plane strain solution for surface uplift above pressurized reservoirs. The solution is based on a Fourier representation of the reservoir pressure. The plane strain model is developed ... -
Geomechanical consequences of large-scale fluid storage in the Utsira Formation in the North Sea
Wangen, Magnus; Gasda, Sarah Eileen; Bjørnarå, Tore Ingvald (Journal article, 2016)In this work we look at the geomechanical implications of injecting large volumes of fluid in the Utsira Formation. Our modelling is based on Biot's poroelasticity in combination with one-phase fluid flow. We study four ... -
Investigation of caprock integrity due to pressure build-up during high-volume injection into the Utsira formation
Gasda, Sarah Eileen; Wangen, Magnus; Bjørnarå, Tore Ingvald; Elenius, Maria (Peer reviewed; Journal article, 2017)In this work, we investigate the pressure-limited storage capacity of the Utsira formation. We employ the use of a simple capacity estimate based on maximum sustainable pressure. Here, the pressure during injection or ...
