Primary Drainage Capillary Pressure Curves in Heterogeneous Carbonates with Ultracentrifuge and NMR
(The University of Bergen, 2010-06-01)
Capillary pressure is one of the most fundamental rock-fluid characteristics in multi-phase flow, critically influencing both the initial reservoir fluid distribution and the dynamic processes of oil recovery. Thus, it is ...
Measurement of seawater by refractometric methods
(The University of Bergen, 2013-08-23)
The aim of this work has been to design and test a refractometer for accurate measurement of seawater refractive index. The goal was to create a refractometer with a cylindrical embodiment and measure refractive ...
Simplified modelling of explosion propagation by dust lifting in coal mines
(School of Engineering and Electronics, University of Edinburgh, 2007)
Dispersion of accumulated layers of combustible dust by turbulent flow or shock waves ahead of the propagating flame may sustain explosion propagation in coal mine galleries and other industrial facilities. The mechanisms ...
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 ...
Modelling of immiscible WAG with emphasis on the effect of capillary pressure
(The University of Bergen, 2008-04-30)
Development and Integration of on-line Data Analysis for the ALICE Experiment
(The University of Bergen, 2009-04-24)
The ALICE detector setup is a dedicated experiment in Heavy Ion Physics, located at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN)/ Geneva. Its various sub-detectors are ...
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 ...
En eksperimentell studie av CO2 lagring i sandstein og kalkstein med bruk av ulike avbildningsteknikker
(The University of Bergen, 2012-11-20)
De naturlige klimagassene sørger for at middeltemperaturen på jorda er ca. 15 C, og ikke -18 C som den ville vært uten klimagassene. De menneskeskapte (antropogene) utslippene av klimagassene CO2, CH4, N2O og fluorholdige ...
High-order harmonic generation from graphene: Strong attosecond pulses with arbitrary polarization
(American Physical Society, 2013-05-03)
We explore high-order harmonic generation (HHG) from a graphene sheet exposed to intense femtosecond laser pulses based on the Lewenstein model. It is demonstrated that the HHG cutoff frequency increases with graphene ...
Measurement of the top quark pair production charge asymmetry in proton-proton collisions at √s = 7 TeV using the ATLAS detector
This paper presents a measurement of the top quark pair ( tt¯ ) production charge asymmetry A C using 4.7 fb−1 of proton-proton collisions at a centre-of-mass energy s√ = 7 TeV collected by the ATLAS detector at the LHC. ...
