Capturing the coupled hydro-mechanical processes occurring during CO2 injection – example from In Salah
(Peer reviewed; Journal article, 2014)At In Salah, CO2 is removed from the production stream of several natural gas fields and re-injected into a deep and relatively thin saline formation, in three different locations. The observed deformation on the surface ... -
Combined positron emission tomography and computed tomography to visualize and quantify fluid flow in sedimentary rocks
(Peer reviewed; Journal article, 2015-09-22)Here we show for the first time the combined positron emission tomography (PET) and computed tomography (CT) imaging of flow processes within porous rocks to quantify the development in local fluid saturations. The coupling ... -
Fault Zone Characterization and Monitoring of CO2 Storage using Full Waveform Inversion
(Master thesis, 2023-06-01)CO2 storage in geological formations is essential to limit global warming and reduce the effects of climate change. In order to store CO2 safely and prevent leakage, proper sealing mechanisms are required. Faults are complex ... -
Fully-implicit simulation of vertical-equilibrium models with hysteresis and capillary fringe
(Peer reviewed; Journal article, 2016-02)Geological carbon storage represents a new and substantial challenge for the subsurface geosciences. To increase understanding and make good engineering decisions, containment processes and large-scale storage operations ... -
The Longyearbyen CO2 Lab: Fluid communication in reservoir and caprock
(Peer reviewed; Journal article, 2017-08)The Longyearbyen CO2 Lab of Svalbard, Norway was established to estimate the potential for geological carbon sequestration at Spitsbergen. Several monitoring wells were drilled in and around the planned CO2 injection site. ... -
On the use of vertically averaged models to simulate CO2 migration in a layered saline aquifer
(Master thesis, 2010-06-01)Geologic and flow characteristics such as permeability and porosity, capillary pressure, geologic structure, and thickness all influence and affect CO2 plume distribution to varying degrees. These parameters do not necessarily ... -
An Open-Source Toolchain for Simulation and Optimization of Aquifer-Wide CO2 Storage
(Peer reviewed; Journal article, 2016-02-04)Planning and execution of large-scale, aquifer-wide CO2 storage operations will require extensive use of computer modelling and simulations. The required computational tools will vary depending on the physical characteristics ... -
Robust simulation of sharp-interface models for fast estimation of CO2 trapping capacity in large-scale aquifer systems
(Peer reviewed; Journal article, 2016-02)Modeling geological carbon storage represents a new and substantial challenge for the subsurface geosciences. To increase understanding and make good engineering decisions, containment processes and large-scale storage ... -
Simulation of geomechanical effects of CO2 injection in cold aquifers with possibility of hydrate formation
(Chapter; Peer reviewed, 2011)The injection of CO2 in saline aquifers can have a significant impact on the geochemistry and the geo-mechanics of the reservoirs. Due to this injection, minerals will dissociate in regions with low pH or precipitate in ... -
Simulation of hydrate dynamics in reservoirs
(Chapter; Peer reviewed, 2011)Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon dioxide ... -
SUCCESS: SUbsurface CO2 storage–Critical elements and superior strategy
(Peer reviewed; Journal article, 2011)SUCCESS is a Center for Environmental Energy Research in Norway and performs research related to geological storage of CO2 in the subsurface. The SUCCESS centre is established by the Research Council of Norway together ... -
Theoretical studies of CO2 hydrates formation and dissociation in cold aquifers using RetrasoCodeBright simulator
(Peer reviewed; Journal article, 2014)Abstract: - Hydrates of CO2 and water can form during aquifer storage if the reservoir has regions where conditions of pressure and temperature are inside the hydrate forming conditions. A very common assumption is that ...
