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 ...
Quality of the Analysis Step in EnKF
(The University of Bergen, 2011-06-15)
In many physical applications we want to characterize the parameters of a system based on indirect observations or measurements. In a reservoir simulator setting, the goal is to simulate the production of hydrocarbons ...
Montøren sitt omsyn til tryggleiksprosedyrar under arbeid med "ikkje-planlagde utfall på HS-anlegg" og utfallsituasjonen sine prestasjonspåverkande faktorar
(The University of Bergen, 2011-05-31)
Dette studiet har teke utgangspunkt i nokre karakteristiske sider ved arbeidsoppgåver som kan påverke handlingar i negativ retning for auka risiko. Desse arbeidsoppgåvene er utført av høgspenning-elektromontørar og ...
The effect of calcite minerale on hydrate stability and CO2 adsorption
(The University of Bergen, 2011-06-01)
The background for conducting this study are the huge unused possibilities for storage of large quantities of the greenhouse gas carbon dioxide in old or depleted oil reservoirs or deep brackish aquifers. The method of ...
Multiphase Flow in Porous Media with Emphasis on CO2 Sequestration
(The University of Bergen, 2011-12-19)
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 ...
Programming with Explicit Dependencies. A Framework for Portable Parallel Programming
Computational devices are rapidly evolving into massively parallel systems. Multicore processors are already standard; high performance processors such as the Cell/BE processor, graphics processing units (GPUs) ...
A 2-D Visualisation Study of the Mechanisms behind Increased Recovery due to Polymer Injection in Sandstone
(The University of Bergen, 2011-11-20)
The potential of synthetic polymer injection, such as hydrolysed polyacrylamide (HPAM), in reservoirs has been a field of study since the 1960's . The main intension of polymer injection is to improve the problems ...
Particle aggregation at the edges of anticyclonic eddies and implications for distribution of biomass
(Copernicus Publications, 2012-06-14)
Acoustic measurements show that the biomass of zooplankton and mesopelagic fish is redistributed by mesoscale variability and that the signal extends over several hundred meters depth. The mechanisms governing this ...
Transport mechanisms for CO2-CH4 exchange and safe CO2 storage in hydrate-bearing sandstone
CO2 injection in hydrate-bearing sediments induces methane (CH4) production while benefitting from CO2 storage, as demonstrated in both core and field scale studies. CH4 hydrates have been formed repeatedly in partially ...
