An Experimental Study of CO2 sequestration in saline aquifers and gas hydrates
(The University of Bergen, 2014-09-10)
Processes related to the displacement of brine by CO2 were studied in core flood experiments in high-permeable, homogeneous Bentheim sandstone using a medical CT scanner. These processes are of high relevance for prediction ...
Experimental study of diffusive oil recovery during low salinity waterflooding and miscible CO2 injection in sandstones and shales
(The University of Bergen, 2014-11-24)
This experimental thesis presents a study of two diffusive EOR techniques; low salinity waterflooding in 2D sandstone silicon wafer micromodels and miscible CO2 injection in tight shale core samples. Tests were conducted ...
Simulation of viscous instabilities in miscible and immiscible displacement
(The University of Bergen, 2008-06-09)
This study includes modeling of viscous instabilities at both miscible and immiscible displacement. Oil recovery of heavy oil leads to unstable displacement for adverse mobility ratio for both miscible and immiscible ...
Vannbasert eor i oppsprukne bergarter - økt oljeutvinning ved kjemikalietilsetning i injeksjonsvannet
(The University of Bergen, 2010-06-01)
En stor del av verdens hydrokarbonreserver finnes i karbonater. Karbonatreservoarer er komplekse fordi reservoarbergarten ofte er sprø og sprekker lett. Mineralsammensetningen av karbonater gjør poreoverflaten mer tilbøyelig ...
Characterization of Hyper Spectral Irradiance and Radiance Sensors
(The University of Bergen, 2013-09-11)
It is surprisingly problematic to to accurately measure light in the laboratory. Even more so when measuring in the field. There are lots of areas where measuring light spectrum and irradiance outside a laboratory is ...
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 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 ...
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 ...
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. ...
A setup for electronic tests of ATLAS silicon strip detectors
(The University of Bergen, 2001)
