3D seismic stratigraphy and reservoir characterization of the Chalk Group in the Norwegian Central Graben, North Sea
(Doctoral thesis, 2011-12-08) -
The Cenozoic western Svalbard margin: sediment geometry and sedimentary processes in an area of ultraslow oceanic spreading
(Peer reviewed; Journal article, 2011-04-17)The northeastern high-latitude North Atlantic is characterised by the Bellsund and Isfjorden fans on the continental slope off west Svalbard, the asymmetrical ultraslow Knipovich spreading ridge and a 1,000 m deep rift ... -
The chalk depositional system in the Central Graben – concepts of regional geology, sedimentology and stratigraphy
(Working paper, 2011-12-08) -
Correlations between the effective permeability and seismic anisotropy of fractured reservoirs
(Doctoral thesis, 2011-08-23)The successful exploitation of many hydrocarbon reservoirs may depend on proper characterization of fractured or composite porous media. However, due to anisotropy and heterogeneity, the characterization of such kind of ... -
Detaljkartlegging av skredfare i Mobergslia, Os kommune, Hordaland
(Master thesis, 2011)Detaljert kartlegging av lausmassane, med hovudfokus på skredavsetjingar og kartlegging av skredfare er utført i området rundt Mobergslia, sør for Liafjellet i Os kommune, Hordaland. Det er laga eit lausmassekart og eit ... -
Estimation of elastic moduli of mixed porous clay composites
(Peer reviewed; Journal article, 2011-01-13)We have developed a procedure for estimating the effective elastic properties of various mixtures of smectite and kaolinite over a range of confining pressures, based on the individual effective elastic properties of pure ... -
Exhumation history and tectonic across the Hardangerfjord Shear Zone, using apatite fission track thermochronology
(Master thesis, 2012-02-09)ABSTRACT The Hardangerfjord Shear Zone (HSZ) is a large scale, ductile low angle shear zone, with SW-NE trending and NW dipping direction in the Caledonian crust. This zone has been formed at about 408-402 Ma (Fossen, 1992, ... -
Experimental investigations of Magnetization processes in Chinese loess
(Doctoral thesis, 2011-11-25) -
Facies Analysis and Sandbody Geometry of the Paleogene Battfjellet Formation, Central Western Nordenskiöld Land, Spitsbergen
(Master thesis, 2010)New sedimentological data from the central part of Nordenskiöld Land, Spitsbergen, contributes to the understanding of the depositional processes and sandbody geometry of the Battfjellet Formation (Eocene). A detailed ... -
From mountains to basins: geochronological case studies from southwestern Norway, Western Australia and East Antarctica
(Doctoral thesis, 2012-03-02) -
High Mountain Melt-Down: Local Perceptions of Global Warming in the Andes and Himalayas
(Master thesis, 2008)Present scientific knowledge about global warming affirms that ice and snow packs in the high mountains of the world are melting at increasing rates (see IPCC 2007 and UNEP 2007). Melting glaciers and receding snowlines ... -
Identifying flood deposits in lake sediments: Changing frequencies and potential links to long-term climate change
(Doctoral thesis, 2011-05-26)This thesis consists of an introduction and three individual papers that investigate the possibility for identifying the sedimentary imprint of catchment processes in lake sediments, emphasising on extreme events and in ... -
Improved quantitative calibration of rock physics models
(Peer reviewed; Journal article, 2011-11)In reservoir characterization, rock-physics models provide the link between seismic observables (density, compressional and shear wavespeeds) and reservoir parameters such as porosity, lithology and fluid saturation. ... -
An integrated approach for seismic characterization of carbonates
(Doctoral thesis, 2010-11-09) -
Integration of ground-based hyperspectral and lidar scanning in virtual outcrop geology
(Doctoral thesis, 2011-01-28)The potential to visualize and analyse geological outcrops in a 3D environment has made terrestrial laser scanning (TLS) a standard method in geological field studies. Lidar models can be integrated with high resolution ... -
Kartlegging av område med potensiell skredfare i Os kommune, Hordaland
(Master thesis, 2011)Frå 2010 trådde plan- og bygningslova i kraft. Den seier at risiko- og sårbarheitanalyse med omsyn på mellom anna skred skal utførast i samanheng med nybygging og merkast på aktsemdkart. Dette er bakgrunnen for at Os ... -

Miocen utvikling av Vøringbassenget, basert på 2D multikanals seismikk
(Master thesis, 2010)2D multikanals seismikk, i kombinasjon med brønndata, er i denne studien benyttet for å studere de kenozoiske sedimentene i Vøringbassenget. I tillegg til den seismiske studien er fire brønner knyttet sammen med det seismiske ... -
Modelling of OBS Data Across the Vestbakken Volcanic Province
(Master thesis, 2011)A P-Wave model of a 384 km long Ocean Bottom Seismometer profile has been modelled by use of ray-tracing. The profile, Bear Island South (BIS-2008), crossses the transtensional Vestbakken Volcanic Province and the boundary ...
