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 ...
Crude oil components with affinity for gas hydrates in petroleum production
(The University of Bergen, 2007-06-28)
Some crude oils are believed to contain natural inhibiting components that can prevent hydrate plugging of oil pipelines in petroleum production. A method for classification of the oils that form hydrate plugs, as opposed ...
Measurement of non-linear acoustoelastic effect in steel using acoustic resonance
(The University of Bergen, 2014-09-25)
Non-destructive stress measurements of structures are increasingly valued by the industry. Ultrasonic methods have the advantage that acoustic waves propagate with ease through materials, making it possible to probe the ...
Robust Multiscale Control-volume Methods for Reservoir Simulation
(The University of Bergen, 2012-04-30)
The impact of lysine and arginine ratios in plant-based protein diets on appetite, growth performance and gene expression of brain neuropeptide Y (NPY) and cholecystokinin (CCK) in juvenile cobia (Rachycentron canadum)
(The University of Bergen, 2013-01-31)
Aquaculture of cobia, Rachycentron canadum is hampered by lack of good feeding protocols and nutritionally optimized diets. Studies on the role of appetite and feeding behavior regulating neuropeptides in cobia have not ...
Biodiversity studies in Afrotropical moth flies (Diptera: Psychodidae)
(The University of Bergen, 2011-09-01)
NB! The nomenclatural acts proposed herein are not validly published according to the International Code of Zoological Nomenclature and must therefore be considered mere suggestions rather than valid scientific names(ICZN, ...
Phylogeography of Phycodrys rubens (Linnaeus) batters from mainland Norway and Svalbard based on nuclear and mtDNA sequences and microsatellites
(The University of Bergen, 2014-04-01)
Phycodrys rubens is a common cold temperate red macroalga in the North Atlantic, a region with a diverse natural history that has shaped the phylogeography for many species. In this study microsatellite loci as well as ...
Modelled mass balance of Xibu glacier, Tibetan Plateau: sensitivity to climate change
(International Glaciological Society, 2010-06-01)
Due to a lack of in situ measurements, model-based studies of glacier mass balance in the Tibetan Plateau are very limited. An energy-balance model is applied to analyse the mass-balance sensitivity of Xibu glacier, in the ...
High resolution seismic stratigraphic analysis: An integrated approach to the subsurface geology of the SE Persian Gulf
