Characterization of Linked Polymer Solutions (LPS) – Influence of salinity and divalent ions
(The University of Bergen, 2011-05-31)
Water flooding with addition of polymers cross-linked by polyvalent ions (LPS) has proven to increase the oil recovery both in field applications and laboratory studies, but with constraints on the brine salinity. With of ...
NMR measurements of wettability alternation in Berea Sandstone
(The University of Bergen, 2011-11-28)
When a new oil reservoir is discovered and a production strategy is chosen the knowledge about wettability characteristics for the field is of outermost importance. Wettability is a key factor for fluid distribution ...
An Experimental Study of Pool Fires and Validation of Different CFD Fire Models
(The University of Bergen, 2011-06-06)
Computer programs developed to predict a possible fire scenario is today an important tool when working with fire safety. In this context different Computational Fluid Dynamics models, so called CFD models, where the domain ...
Optimization Models for Turbine Location in Wind Farms
(The University of Bergen, 2012-05-24)
The topic of this thesis is wind farm optimization. The goal is to be able to decide where to install wind turbines within a given region in order to maximize the power output in two different scenarios: For a fixed number ...
Methane and carbon dioxide exchange production studies from exposed natural gas hydrate
(The University of Bergen, 2010)
Two laboratory experimental setups have been designed in collaboration with the Reservoir Physics Group at the Department of Physics and Technology. The equipments have been completed and tested. The first experiment was ...
Comparison of residual oil cluster size distribution, morphology and saturation in oil-wet and water-wet sandstone
We imaged an oil-wet sandstone at residual oil saturation (Sor) conditions using X-ray micro-tomography with a nominal voxel size of (9 μm)3 and monochromatic light from a synchrotron source. The sandstone was rendered ...
Multiphase Flow in Porous Media with Emphasis on CO2 Sequestration
(The University of Bergen, 2011-12-19)
Formulas as programs
Alma-0 is a programming language supporting declarative programming, which combines the advantages of imperative and logic programming paradigms. This work explores declarative programming by extending the interpretation ...
The Effect of Fluid Viscosity on Hydrocyclone Performance: Design and Commissioning of an Experimental Rig and Results
(The University of Bergen, 2011-06-30)
Hydrocyclones are used in the process industry for a variety of applications. The product streams from the wells in the oil and gas industry include produced sand, which have to be removed as it interferes with control ...
Karakterisering av strømning gjennom en forkastning med fault facies- og standardmodell ved bruk av reservoarsimulator
(The University of Bergen, 2011-11-21)
Forkastninger har en betydelig innvirkning på strømninger i et reservoar. Hittil har forkastninger blitt modellert som en flate eller et plan i vanlige reservoarsimulatorer, men studier har vist at forkastninger ofte må ...
