Energi til norsk veksthusnæring - bruk av naturgass som energibærer og CO2-kilde
(Bioforsk Rapport;, Research report, 2006)Norsk gartnerinæring bruker anslagsvis 1 000 GWh per år. Planteproduksjon i veksthus her i landet har stort behov for elektrisk energi og avhengig av kultur og produksjonsopplegg varierer andelen elektrisk energi fra 50-80 ... -
Jurassic to Early Cretaceous basin configuration(s) in the Fingerdjupet Subbasin, SW Barents Sea
(Journal article; Peer reviewed, 2017-06)The Fingerdjupet Subbasin in the southwestern Barents Sea sits in a key tectonic location between deep rifts in the west and more stable platform areas in the east. Its evolution is characterized by extensional reactivation ... -
Structural evolution of sheared margin basins: the role of strain partitioning. Sørvestsnaget Basin, Norwegian Barents Sea
(Journal article; Peer reviewed, 2017-07)Spatio-temporal analysis of basins formed along sheared margins has received much less attention than those formed along orthogonally extended margins. Knowledge about the structural evolution of such basins is important ... -
Porosity Evolution during Chemo-Mechanical Compaction
(Chapter, 2018)This chapter presents the constitutive equations necessary to interpret laboratory and field data when both solid and pore volume evolve through time due to chemical and mechanical processes. The equations for the porosity ... -
Investigation of a new application for cellulose nanocrystals: a study of the enhanced oil recovery potential by use of a green additive
(Journal article; Peer reviewed, 2018-02)Cellulose nanocrystals (CNC) were investigated for use in a potential new application, enhanced oil recovery. Core flooding experiments were performed on outcrop sandstone cores using CNC particles dispersed in low salinity ... -
Adhesive forces between two cleaved calcite surfaces in NaCl solutions: The importance of ionic strength and normal loading
(Journal article; Peer reviewed, 2018-12-15)The mechanical strength of calcite bearing rocks is influenced by pore fluid chemistry due to the variation in nano-scale surface forces acting at the grain contacts or close to the fracture tips. The adhesion of two ... -
Effects of pore fluids on quasi‐static shear modulus caused by pore‐scale interfacial phenomena
(Peer reviewed; Journal article, 2019)It is evident from the laboratory experiments that shear moduli of different porous isotropic rocks may show softening behaviour upon saturation. The shear softening means that the shear modulus of dry samples is higher ... -
Time lapse seismic analysis of the Tohoku-Oki 2011 earthquake
(Peer reviewed; Journal article, 2019)A detailed time lapse seismic analysis of subsurface movements is presented using seismic 2D lines acquired prior to and after the Tohoku-Oki earthquake offshore Japan in 2011. Estimated movements of the seabed from the ... -
Simulation of immiscible WAG injection in a stratified reservoir -- performance characterization using a new dimensionless number
(Peer reviewed; Journal article, 2019)Water alternating gas (WAG) is a well‐established enhanced‐oil‐recovery process where gas and water are injected in alternating fashion. Good volumetric sweep is achieved as water and gas target both the oil residing in ... -
A laboratory scale approach to wettability restoration in chalk core samples
(Peer reviewed; Journal article, 2019)Wettability in chalk has been studied comprehensively to understand fluid flow mechanisms impacting coreflooding experiments. Wettability becomes paramount in understanding the parameters influencing chalk-fluid interactions. ... -
Modelling of creep compacting outcrop chalks injected with Ca-Mg-Na-Cl brines at reservoir conditions
(Peer reviewed; Journal article, 2019)Numerical and analytical 1D solutions are presented to interpret the link between geochemical alterations and creep compaction (compaction under constant effective stress) in chalk cores. Chemically reactive flow enhancing ... -
Bulk moduli and seismic attenuation in partially saturated rocks: hysteresis of liquid bridges effect
(Journal article; Peer reviewed, 2019-03-20)A key task of exploration geophysics is to find relationships between seismic attributes (velocities and attenuation) and fluid properties (saturation and pore pressure). Experimental data suggests that at least three ... -
The Impact of Salt Tectonics on the Thermal Evolution and the Petroleum System of Confined Rift Basins: Insights from Basin Modeling of the Nordkapp Basin, Norwegian Barents Sea
(Peer reviewed; Journal article, 2019-07)Although the thermal effect of large salt tongues and allochthonous salt sheets in passive margins is described in the literature, little is known about the thermal effect of salt structures in confined rift basins where ... -
Mineral replacement in long-term flooded porous carbonate rocks
(Peer reviewed; Journal article, 2019-09)This study reports mineralogical and physical property changes linked to geo-chemical alterations processes during three ultra-long-term tri-axial tests on outcrop-chalk from Liège (Belgium). The test core plugs were flooded ... -
Effective fluid bulk modulus in the partially saturated rock and the amplitude dispersion effects
(Peer reviewed; Journal article, 2020)Frequency dispersion is a well-known effect in geophysics, which means that waves of different wavelengths propagate at different velocities. Amplitude dispersion is a less-known effect, which means that waves of different ... -
The missing link of Rodinia break up in western South America: A petrographical, geochemical, and zircon Pb-Hf isotope study of the volcanosedimentary Chilla beds (Altiplano, Bolivia)
(Peer reviewed; Journal article, 2020)The assembly of Rodinia involved the collision of eastern Laurentia with southwestern Amazonia at ca. 1 Ga. The tectonostratigraphic record of the central Andes records a gap of ∼300 m.y. between 1000 Ma and 700 Ma, i.e., ... -
Simulation study of wettability alteration enhanced oil recovery during co-current spontaneous imbibition
(Peer reviewed; Journal article, 2020)Naturally fractured reservoirs are highly dependent on capillary forces to recover hydrocarbons during water injection. Water can spontaneously imbibe and expel oil if positive capillary forces exist; purely counter-current ... -
Analysis of filtering techniques for investigating landslide-induced topographic changes in the Oetz Valley (Tyrol, Austria)
