Multiphoton ionization and stabilization of helium in superintense xuv fields
(American Physical Society, 2011)
Multiphoton ionization of helium is investigated in the superintense field regime, with particular emphasis on the role of the electron-electron interaction in the ionization and stabilization dynamics. To accomplish this, ...
Numerical Modeling of Supercritical ‘Out-Salting’ in the “Atlantis II Deep” (Red Sea) Hydrothermal System
(Bentham Open, 2007)
Supercritical water behaves close to that of a non-polar fluid and its ability to dissolve salt ions is very low. In rifting locations world-wide, where hot vents occur, it has been shown that seawater attains supercritical ...
Pore-to-Core Laboratory Upscaling and Visualization of Enhanced Oil Recovery and CO2 Storage
(The University of Bergen, 2015-01-09)
<p>The global energy demand increases, and the need for hydrocarbon reserve growth is evident. The maturation of hydrocarbon formations worldwide combined with declining rate of major oil and gas discoveries, have caused ...
An Experimental Study of the Influence of Major Damage of Flame Gap Surfaces in Flameproof Apparatus on the Ability of the Gaps to Prevent Gas Explosion Transmission
(The University of Bergen, 2010-06-10)
Electrical apparatuses for use in the presence of explosive gas atmospheres have to be specially designed to prevent them from igniting the explosive gas. Flameproof design implies that electrical components producing ...
Enhanced Oil Recovery by CO2 and CO2-foam Injection in Fractured Limestone Rocks
(The University of Bergen, 2013-06-03)
This thesis is part of an ongoing study of integrated enhanced oil recovery methods in Reservoir Physics group at the Department of Physics and Technology at the University of Bergen. This experimental thesis investigates ...
Flow Components and Initial State CM Fluctuations
(Jagiellonian University, 2012)
At the LHC, the strong collective flow is observed in Pb+Pb collisions, as shown by the azimuthal correlations in the transverse-momentum distributions of the produced particles. We calculate flow components in a relativistic ...
Observations of field aligned currents in the plasma sheet. Two kinds of field aligned currents generated during magnetotail convection
(The University of Bergen, 2009-05-08)
Hydrate Formation and CH4 Production from Natural Gas Hydrates - Emphasis on Boundary Conditions and Production Methods
(The University of Bergen, 2009-05-13)
Natural gas hydrate is a solid state of gas and water at low temperature and high pressure. Gas hydrates are known to form hydrate plugs in production line, and has thus generally been considered a problem to the oil ...
