Monotonicity Conditions for Discretization of Parabolic Conservation Laws
(Master thesis, 2009-06-02)In the recent years monotonicity of control volume methods for elliptic equations has been studied. A discrete maximum principle is established in Keilegavlen et al. [18], and a set of monotonicity conditions on general ... -
Multidimensional Fourier Transform on Sparse Grids
(Master thesis, 2009-06-01)When working on multidimensional problems, the number of points needed when using a tensor product grid. This is known as the curse of dimensionality. In this thesis we propose a set of sparse grids, which can be used to ... -
A Multiscale Approach to Estimate Large Scale Flow and Leakage from Geological Storage
(Master thesis, 2010-06-01)Deep saline aquifers offer the greatest storage capacity for geological storage. However, the formations might be extensive and because of the oil and gas legacy the aquifers are frequently perforated by abandoned wells. ... -
Non-commutative Harmonic Analysis: Generalization of Phase Correlation to the Euclidean Motion Group
(Master thesis, 2010-06-10)This thesis is about noncommutative harmonic analysis, and generalization of phase correlation to the euclidean motion group and application in image processing. -
Nonhydrostatic pressure in ocean models with focus on wind driven internal waves
(Doctoral thesis, 2010-02-05) -
Numerical methods for modeling geothermal energy extraction
(Master thesis, 2009-11-20)Modeling of flow in porous media is an important scientific research area, and has been so for decades. It is also one of the major topics within applied mathematics. Models for flow in porous media are for example important ... -
Numerical modeling of shear stimulation in naturally fractured geothermal reservoirs
(Doctoral thesis, 2018-03-22)Shear-dilation-based hydraulic stimulations are conducted to create enhanced geothermal systems (EGS) from low permeable geothermal reservoirs, which are initially not amenable to energy production. Reservoir stimulations ... -

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 ... -
Postinjection Normal Closure of Fractures as a Mechanism for Induced Seismicity
(Peer reviewed; Journal article, 2017-10-04)Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns related to hydraulic stimulation in Enhanced ... -
