Petrophysical characterization in paleokarst and effect on reservoir properties
(The University of Bergen, 2012-06-29)
Karst is a geological process that can enhance porosity and permeability within a carbonate succession, thus affecting the heterogeneity producing a substantial effect on the fluid flow. The subject is not widely explored ...
Impacts on oil recovery from capillary pressure and capillary heterogeneities
(The University of Bergen, 2008-06-02)
This thesis summarises the findings made in NFR-funded project “Capillary Pressure and Capillary Heterogeneities”. The focus has been to determine the impact on oil recovery from wettability and fractures in carbonate ...
Effect of ultraviolet radiation on phytoplankton photosynthesis measured using fiber-optical oxygen sensors.
(The University of Bergen, 2009-12-08)
Since the discovery of the Antarctic ozone hole' many studies have been conducted to determine the effect of UV radiation on photosynthetic rate of phytoplankton. It is accepted now that increased levels of UV radiation ...
Gamma-ray flow imaging
(The University of Bergen, 1992-03)
Enhanced Oil Recovery by CO2 and CO2-Foam in Fractured Carbonates
(The University of Bergen, 2013-06-04)
This thesis is a part of an ongoing study of integrated enhanced oil recovery methods in the Reservoir Physics research group at the Department of Physics and Technology at the University of Bergen. The aim of this thesis ...
Measurement of seawater refractive index and salinity by means of optical refraction
(The University of Bergen, 2012-05-22)
The aim of this work has been to construct and test a compact refractometer for accurate measurement of seawater refractive index and salinity. The specific goal was to measure the refractive index of the water sample with ...
Photon, neutrino and charged particle spectra from R-violating gravitino decays
We study photonic, neutrino and charged particle signatures from slow decays of gravitino dark matter in supersymmetric theories where R-parity is explicitly broken by trilinear operators. Photons and (anti-)fermions from ...
CO2 injeksjon for økt oljeutvinning i kalk
(The University of Bergen, 2013-05-31)
Denne masteroppgaven studerer CO2 injeksjon for økt oljeutvinning i kalkstein, og hvordan parametere som sprekker, initielt vann og mobilitetskontroll påvirker oljeproduksjon. Det ble gjennomført 15 eksperimenter med ...
Calibration of the ALICE Photon Spectromter (PHOS) using the neutral pion to gamma gamma decay
(The University of Bergen, 2009-09-01)
The Large Hadron Collider (LHC) is under construction beneath the border between Switzerland and France. If it is successful, it will accelerate and collide protons at 7 T eV per proton in center of mass. Furthermore, it ...
An Experimental Investigation on the Effect of Nitrogen Enriched Air and Heat Transfer on the Maximum Experimental Safe Gap for Propane Gas Explosions
(The University of Bergen, 2012-06-15)
Electrical apparatuses for use in potentially explosive gas atmospheres are required to be enclosed. There are two main requirements in the design of such enclosures. Firstly, they are required to withstand the pressure ...
