A Two-Fluid Model for Vertical Flow Applied to CO2 Injection Wells
Linga, Gaute; Lund, Halvor (Journal article; Peer reviewed, 2016)Flow of CO2 in wells is associated with substantial variations in thermophysical properties downhole, due to the coupled transient processes involved: complex flow patterns, density changes, phase transitions, and heat ... -
Avoiding Damage of CO2 Injection Wells Caused by Temperature Variations
Torsæter, Malin; Todorovic, Jelena; Lavrov, Alexandre; Gawel, Kamila; Lund, Halvor; Roy, Pratanu; Carroll, Susan (Journal article; Peer reviewed, 2017)Well integrity is a prerequisite for safe geological storage of CO2. Both active and abandoned wells are man-made channels between the storage reservoir and the atmosphere that can become leakage paths over time. The CO2 ... -
CO2 pipeline integrity: A new evaluation methodology
Berstad, Torodd; Dørum, Cato; Jakobsen, Jana Poplsteinova; Kragset, Steinar; Li, Hailong; Lund, Halvor; Morin, Alexandre; Munkejord, Svend Tollak; Mølnvik, Mona Jacobsen; Nordhagen, Håkon Ottar; Østby, Erling (Peer reviewed; Journal article, 2011)A coupled fluid-structure model for pipeline integrity simulations has been developed. The pipe material and fracture propagation have been modelled using the finite-element method with a local fracture criterion. The ... -
Depressurization of carbon dioxide in pipelines- Models and methods
Lund, Halvor; Flåtten, Tore; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2011)A model for two-phase carbon dioxide transport with phase transfer in pipelines is presented. The stiffened-gas equation of state is used for calculating thermodynamical properties. The convergence and accuracy of two ... -
Dynamic Simulation of CO2 Injection Wells
Munkejord, Svend Tollak; Hammer, Morten; Ervik, Åsmund; Lund, Halvor; Skarsvåg, Hans Langva; Odsæter, Lars Hov (Journal article, 2019) -
Potential of enhancing a natural convection loop with a thermomagnetically pumped ferrofluid
Aursand, Eskil; Gjennestad, Magnus Aashammer; Lervåg, Karl Yngve; Lund, Halvor (Journal article; Peer reviewed, 2016) -
Study of Thermal Variations in Wells During Carbon Dioxide Injection
Lund, Halvor; Torsæter, Malin; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2016)Carbon dioxide (CO2) can be injected into the subsurface for the purpose of enhanced oil recovery (EOR), possibly with geological CO2 storage. This procedure brings about a set of unique challenges with respect to well ... -
Thermo-Fluid-Dynamical Modelling of Salt Precipitation During Co2 Injection in Saline Aquifers, and the Effect on Injectivity
Ervik, Åsmund; Lund, Halvor; Hammer, Morten; Aasen, Ailo; Matas, Berta Güell (Journal article, 2019) -
Towards a thorough Validation of Simulation Tools for CO2 Pipeline Transport
Drescher, Michael; Fahmi, Adil; Aursand, Peder; Hammer, Morten; Lund, Halvor; Stang, Hans Georg Jacob; Austegard, Anders (Journal article; Peer reviewed, 2017)In this work the Schlumberger flow assurance tool OLGA and SINTEF Energy Research in-house CFD tool are assessed for their ability to describe depressurization behaviour of CO2 pipelines. For this purpose, three full-bore ... -
Well integrity for CO2 injection from ships: Simulation of the effect of flow and material parameters on thermal stresses
Aursand, Peder; Hammer, Morten; Lavrov, Alexandre; Lund, Halvor; Munkejord, Svend Tollak; Torsæter, Malin (Journal article; Peer reviewed, 2017)Ships have been shown to be the most cost-effective way to transport CO2 from many sources in the Nordic region to offshore storage sites. Injection from ships introduces new challenges for the integrity of CO2 injection ...
