A Three-Dimensional Analytical Solution for Reservoir Expansion, Surface Uplift and Caprock Stress Due to Pressurized Reservoirs
Wangen, Magnus; Halvorsen, Gotskalk (Journal article; Peer reviewed, 2019)An analytical solution is presented for the displacement, strain and stress of a three-dimensional poro-elastic model with three layers, where the three layers are an underburden, a reservoir with a given fluid pressure, ... -
An analytical plane-strain solution for surface uplift due to pressurized reservoirs
Wangen, Magnus; Halvorsen, Gotskalk; Gasda, Sarah Eileen; Bjørnarå, Tore Ingvald (Journal article; Peer reviewed, 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 ... -
Assessment of CO2 storage capacity based on sparse data: Skade Formation
Elenius, Maria; Skurtveit, Elin; Yarushina, Viktoriya M.; Baig, Irfan; Sundal, Anja; Wangen, Magnus; Landschulze, Karin; Kaufmann, Roland; Choi, Jung Chan; Hellevang, Helge; Podladchikov, Yuri; Aavatsmark, Ivar; Gasda, Sarah (Journal article; Peer reviewed, 2018)Large North Sea aquifers of high quality are the likely major target for 12 Gt of European CO2 emissions that should be stored in the subsurface by 2050. This involves an upscaling of the present combined injection rate ... -
Coupled Basin and Hydro-Mechanical Modeling of Gas Chimney Formation: The SW Barents Sea
Peshkov, Georgy A.; Khakimova, Lyudmila A.; Grishko, Elena V.; Wangen, Magnus; Yarushina, Viktoriya M. (Peer reviewed; Journal article, 2021) -

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; Peer reviewed, 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 (Journal article; Peer reviewed, 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 ... -
A model of fluid expulsion from compacting tight sedimentary rocks based on the Toggle-Switch algorithm
Wangen, Magnus (Peer reviewed; Journal article, 2022) -
Models for Calcium Carbonate Precipitation in the Near-Well Zone by Degassing of CO2
Wangen, Magnus; Sagen, Jan; Bjørnstad, Tor; Johansen, Harald; Souche, Alban Jean-Rene (Journal article; Peer reviewed, 2016)Calcium carbonate scale formation is a well known problem for water producing wells. Although there are several types of scale forming processes, we investigate the case of calcium carbonate precipitation when the degassing ... -
