Simulation of hydrate dynamics in reservoirs
(International Conference on Gas Hydrates, 2011)
Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon ...
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 ...
Monte Carlo simulations of radiative transport in the atmosphere and ocean
(The University of Bergen, 2001)
Measurement of the muon reconstruction performance of the ATLAS detector using 2011 and 2012 LHC proton–proton collision data
This paper presents the performance of the ATLAS muon reconstruction during the LHC run with pp collisions at √s = 7–8 TeV in 2011–2012, focusing mainly on data collected in 2012. Measurements of the reconstruction efficiency ...
Effect of Combined Low Salinity and Surfactant Injection on Oil Recovery in Aged Bentheimer Sandstones at Different Temperatures
(The University of Bergen, 2012-06-01)
A moderate increase in crude oil recovery by reduction in salinity of the injection brine has been observed for numerous laboratory core flood experiments. The underlying mechanisms behind increased recovery by low ...
Adaptive transdure basert på tidsreversering. Målinger på en 5x5 array prototype
(The University of Bergen, 2009-06-11)
Utvikling av adaptiv transduserarray som er ment for tidsreverserende bruk på en olje/gass-separator. Prinsippet består i styring av en transduser oppdelt i små ankeltceller (array). Hver celle styres av sin egen ...
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 ...
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 ...
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 ...
High voltage electrical discharges in the laboratory
(The University of Bergen, 2014-12-18)
A new phenomenon called terrestrial gamma-ray flashes (TGFs) was discovered early in the 1990s by the NASA satellite Compton Gamma-Ray Observatory. The short-duration bursts of highly energetic gamma-rays are caused by ...
