Geometrically derived efficiency of slow immiscible displacement in porous media
(Peer reviewed; Journal article, 2020)The efficiency of a displacement is the fraction of applied work over the change in free energy. This displacement efficiency is essential for linking wettability to applied work during displacement processes. We quantify ... -
Geophysical characterisation of two segments of the Møre-Trøndelag Fault Complex, Mid-Norway
(Journal article; Peer reviewed, 2011)The Møre-Trøndelag Fault Complex (MTFC) has controlled the tectonic evolution of Mid Norway and its shelf for the past 400 Myr through repeated reactivations during Palaeozoic, Mesozoic and perhaps Cenozoic times, the very ... -
Geophysical expression of the Leka Ophiolite, Norway modeled from integrated gravity, magnetic and petrophysical data
(Journal article; Peer reviewed, 2018)The ca. 497 Ma Leka Ophiolite Complex (LOC) comprises oceanic lithosphere that formed near the margin of Laurentia in a suprasubductionzone setting. The LOC was obducted onto Laurentia in the Early Ordovician and later ... -
Geophysical Mapping and Paleomagnetic Study of the Leka Ophiolite Complex
(Doctoral theses at NTNU;2019:32, Doctoral thesis, 2019)This thesis presents the results of a geophysical study of the Leka Ophiolite Complex (LOC) in central Norway, carried out to refine the understanding of the LOC’s sub surface geometry, fault structure and structural ... -
Geophysical mapping of the mafic and ultramafic rocks of the Seiland Igneous Province from the kilometer to the micrometer scale
(Doctoral theses at NTNU;2018:328, Doctoral thesis, 2018)The Seiland Igneous Province (SIP) is the largest complex of mafic and ultramafic intrusions in northern Norway, and one of the best preserved deep-seated magmatic plumbing systems in the world. The province, generated ... -
Geophysical Monitoring of CO2 Injection in Saline Aquifers
(Doctoral thesis at NTNU;2014:267, Doctoral thesis, 2014)Carbon capture and storage (CCS) is a prerequisite to meet the internationally agreed upon target of limiting the emissions of CO2. The international energy agency has a goal that CCS should cover 14% of the CO2 emission ... -
Geoscience for CO2 storage: an introduction to the thematic collection
(Peer reviewed; Journal article, 2022)This is a summary of a collection of 12 research papers in a thematic set. It is clear that in the transition towards a carbon-neutral future, CO2 storage will be a critical technology for decarbonization of society, ... -
Geosciences and Reservoir Engineering Aspects in Optimizing Katla Field Development Plan
(Master thesis, 2011)Katla field was selected to be one of the first fast track projects in 2010. The field is operated by Statoil and the co-owners are Total, Petoro, Exxon Mobile and Conoco Phillips. The Katla template is connected to Oseberg ... -
Geospatial Analysis of Copper-Rich Ferromanganese Crust and Seafloor Massive Sulfide Occurrences on the Extended Norwegian Continental Shelf
(Master thesis, 2023)SAMMENDRAG Hovedmål for forskningen: Geospatial Analyse av kobberrike ferromanganesekruster og seafloor massive sulfideforekomster på et utvalgt fragment av den utvidede norske kontinentalsokkelen. Studiens omfang: ... -
Gevingåsen tunnel: Injeksjon og effekten av berginjeksjon i Gevingåsens bergarter
(Master thesis, 2010)Tunneldriving gir en potensiell risiko for uventede grunnforhold. En slik risiko er å treffe på store mengder grunnvann under høyt trykk. Men også mindre vannlekkasjer kan skape problemer i tunneler eller i omgivelsene. ... -
Giant paleo-seafloor craters and mass wasting associated with magma-induced uplift of the upper crust
(Peer reviewed; Journal article, 2022)Giant seafloor craters are known along many a continental margin with recurrent mass-wasting deposits. However, the impact of breakup-related magmatism on the evolution of such craters is barely understood. Using high-quality ... -
Gibbs-like phenomenon inherent in a lumped element model of a rod
(Journal article; Peer reviewed, 2017)The underlying assumption of a lumped element model is that a spatially distributed physical system can be approximated by a topology of discrete entities. The impact of this assumption is illustrated by a model of a ... -
GIS-analyse av terrengendringer i kvikkleirefarlige områder med eksempler fra Trøndelag
(Master thesis, 2023)I Norge har det gått en rekke kvikkleireskred gjennom historien. Noen av disse har knapt vært merkbare, mens andre har fått katastrofale følger. Gjerdrumskredet i 2020 er et eksempel på det siste, da det resulterte i store ... -
Gjennomførbarhet for bruk av TBM ved Rogfast
(Master thesis, 2013)Den planlagte undersjøiske veitunnelen mellom Randaberg og Bokn vil bli verdens lengste i sitt slag. Med 25,5 km to-løpstunnel vil Rogfast bli en ny milepel i tunnelbygging. Rogfast vil også være den dypeste (ca. 390 m ... -
Gjennomførbarhet med roadheader som drivemetode på ny togtunnel i Oslo
(Master thesis, 2021)Fram mot 2040 er det forventet en betydelig befolkningsvekst på Østlandet. For å håndtere flere reisende må togkapasiteten gjennom Oslo sentrum økes. Begrensede arealer i dagen gjør at mulighetene i undergrunnen må utnyttes. ... -
Glacial geomorphology and Late Quaternary glacial History of Hornstrandir, NW Iceland
(Master thesis, 2015)The Late Quaternary and Holocene glacial history of Hornstrandir, NW Iceland, have been investigated. The area is of special interest because it s almost unstudied. Several researchers have proposed that ice free plateaux ... -
Glacial, fluvial and contour-current-derived sedimentation along the northern North Sea margin through the Quaternary
(Peer reviewed; Journal article, 2021)The thick sequence of Quaternary sediments preserved within the northern North Sea contains important information about the glacial history, palaeo-oceanographic conditions and slope stability of this region during the ... -
Global existence and decay estimates of the Boltzmann equation with frictional force
