An approximate hybrid method for modeling of electromagnetic scattering from an underground target
(The University of Bergen, 2010-12-09)
The detection of a potential petroleum reservoir is achieved through inversion of electromagnetic data acquired in sea floor receivers. Inversion of electromagnetic data requires a number of repeated solves of the ...
(The University of Bergen, 2012-04-23)
Methods for probability density estimation are traditionally classified as either parametric or non-parametric. Fitting a parametric model to observations is generally a good idea when we have sufficient information ...
Dualgraden til noen determinentelle varieteter
(The University of Bergen, 2008)
Field-case simulation of CO2-plume migration using vertical-equilibrium models
When injected in deep saline aquifers, CO2 moves radially away from the injection well and progressively higher in the formation because of buoyancy forces. Analyzes have shown that after the injection period, CO2 will ...
Determining individual variation in growth and its implication for life-history and population processes using the Empirical Bayes method
The differences in demographic and life-history processes between organisms living in the same population have important consequences for ecological and evolutionary dynamics. Modern statistical and computational methods ...
Dynamic Capillary Effects in the Simulation of Flow and Transport in Porous Media: A New Linearisation Method
(The University of Bergen, 2014-12-25)
In this thesis mathematical models with and without dynamic capillary effects are developed to model water flow and solute transport through a porous medium. The system of equations are discretised using the finite volume ...
Robust Control Volume Methods for Reservoir Simulation on Challenging Grids
(The University of Bergen, 2010-02-19)
Optimization of CO2 Geological Storage Cost
(The University of Bergen, 2013-12-01)
Carbon dioxide capture and storage (CCS) is a promising strategy to battle the climate change by injecting large-scale of carbon dioxide back to underground formations and storing the carbon dioxide possibly permanently. ...
Numerical Tools for Multicomponent, Multiphase, Reactive Processes: Flow of CO2 in Porous Medium
(The University of Bergen, 2006-06-02)
Electrical conductivity of fractured media: A computational study of the self-consistent method
(Society of Exploration Geophysicists, 2012)
Effective medium theory can be used to link conductivity estimation methods with prior knowledge about the distribution of fractures in the investigated geological structure. In the literature, little work has been ...
