  • Gauteplass, Jarand; Chaudhary, Kuldeep; Kovscek, Anthony R.; Fernø, Martin A. (Journal article, Elsevier, 2015-03-05)
    Pore-level foam generation, propagation, and sweep efficiency were visualized using silicon-wafer micromodels with an accurate representation of sandstone pore structure, grain shapes and sizes based on thin-section analysis. ...
  • Chang, Yu-Fen; Hoffmann, Alex Christian (Journal article, Springer, 2015-01-10)
    In this study the liquid flow in a reverse-flow hydrocyclone is studied experimentally using the Lagrangian approach. Resin beads with densities that are close to the density of the liquid in which they move, i.e. ...
  • Gauteplass, Jarand (Doctoral thesis, The University of Bergen, 2015-01-09)
    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 ...
  • Grøndahl, Øystein (Master thesis, 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 ...
  • Wang, Du-Juan (Doctoral thesis, The University of Bergen, 2014-12-16)
    In our computational fluid dynamics (CFD) calculations the Kelvin-Helmholtz instability (KHI) starts to develop in peripheral collisions. At high energies the shear viscosity of the Quark Gluon Plasma (QGP) flow is ...
  • Selvåg, Julia (Master thesis, The University of Bergen, 2014-12-05)
    Primær oljeutvinning ved trykkavlastning gir ofte lav utvinningsgrad, og etterlater stor restoljemetning i reservoaret. For å forbedre oljeutvinningsgraden kan andre produksjonsmetoder benyttes; vanninjeksjon har i lang ...
  • Fredriksen, Sunniva Brudvik (Master thesis, 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 ...
  • Johansen, Marius Ole (Master thesis, The University of Bergen, 2014-11-20)
    The ALICE detector at CERN is a promising tool for the study of the Quark-Gluon Plasma (QGP), an exotic state of matter thought to be present in the early Universe. The study of partonic energy loss reveals vital information ...
  • Holme, Morten Norlemann (Master thesis, The University of Bergen, 2014-11-20)
    This thesis describes an experimental investigation of applying photodiodes as sensors inside flame detectors exposed to laminar, transient and turbulent gas explosions, and reflecting environment of various degrees. ...
  • Haaland, Stein; Reistad, Jone Peter; Tenfjord, Paul; Gjerloev, Jesper W.; Maes, Lukas; deKeyser, Johan; Maggiolo, Romain; Anekallu, Chrandrasehkar; Dorville, Nicolas (Journal article, WileyAmerican Geophysical Union, 2014-11)
    The magnetopause is a current sheet forming the boundary between the geomagnetic field on one side and the shocked solar wind on the other side. This paper discusses properties of the low-latitude dawn and dusk flanks ...
  • Jemai, Khaled (Doctoral thesis, The University of Bergen, 2014-10-24)
  • Kulkarni, Anuli Avinash (Master thesis, The University of Bergen, 2014-10-16)
    The growth of natural gas transport by pipeline has led to the establishment of a large network of pipelines throughout the world [1]. Transport of natural gas through a network of pipelines is a challenging issue, mainly ...

    This paper presents the electron and photon energy calibration achieved with the ATLAS detector using about 25 fb −1 of LHC proton–proton collision data taken at centre-of-mass energies of s√=7 and 8 TeV. The reconstruction ...
  • Eldevik, Simen (Doctoral thesis, The University of Bergen, 2014-09-25)
    Non-destructive stress measurements of structures are increasingly valued by the industry. Ultrasonic methods have the advantage that acoustic waves propagate with ease through materials, making it possible to probe the ...
  • Brattekås, Bergit (Doctoral thesis, The University of Bergen, 2014-09-19)
  • Paulsen, Vegard Havre (Master thesis, 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 ...
  • Pettersen, Birgitte (Master thesis, The University of Bergen, 2014-09-01)
    Anvendelsen av silika nanopartikler for EOR-formål krever stabile dispersjoner ved typiske reservoarforhold. Optimale silikadispersjoner vil være stabile over lengre tid ved nøytrale pH- verdier og høye elektrolyttko ...
  • Csernai, Laszlo; Wang, Du-Juan; Bleicher, Marcus; Stöcker, Horst (Journal article, American Physical Society, 2014-08-29)
    The flow vorticity development is studied in the reaction plane of peripheral relativistic heavy-ion reactions at energies just above the threshold of the transition to a quark-gluon plasma (QGP). Earlier calculations at ...
  • Csernai, Laszlo; Wang, Du-Juan; Csörgo, T. (Journal article, American Physical Society, 2014-08-01)
    We study an exact and extended solution of the fluid dynamical model of heavy ion reactions and estimate the rate of slowing down of the rotation due to the longitudinal and transverse expansion of the system. The initial ...
