The graphite occurrences of Northern Norway, a review of geology, geophysics, and resources
(Peer reviewed; Journal article, 2020)There are three provinces in Northern Norway in which occurrences of graphite are abundant; the Island of Senja, the Vesterålen archipelago, and the Holandsfjorden area. From these provinces, we report graphite resources ... -
3D interpretation of helicopter-borne frequency-domain electromagnetic (HEM) data from Ramså Basin and adjacent areas at Andøya, Norway
(Peer reviewed; Journal article, 2020)The Ramså Basin is situated on the strandflat on the northeastern side of Andøya between Ramså and Skarstein. It is the only known Mesozoic sedimentary basin onshore Norway and therefore represents an easily accessible ... -
Experimental investigation of stability of silica nanoparticles at reservoir conditions for enhanced oil-recovery applications
(Peer reviewed; Journal article, 2020)To be effective enhanced oil-recovery (EOR) agents, nanoparticles must be stable and be transported through a reservoir. However, the stability of a nanoparticle suspension at reservoir salinity and temperature is still a ... -
Permo–Triassic sedimentary fills and tectonic phases off Mid Norway: seismic investigation of the Trøndelag Platform
(Peer reviewed; Journal article, 2020)Seismic interpretation (2D and new 3D surveys) has been used to investigate sedimentary fills and timing of tectonic activity offshore Mid Norway. This study was focused on upper Permian and Lower Triassic sedimentary basin ... -
Dynamic wettability alteration for combined low salinity brine injection and surfactant flooding on silica surface
(Peer reviewed; Journal article, 2020)Experimental results of dynamic contact angle measurements of low salinity brine and combined low salinity water and surfactant flooding (LSW–SF) on silica surface are presented in this study. Dynamic contact angle experiments ... -
Experimental investigation of the effect of adding nanoparticles to polymer flooding in water-wet micromodels
(Peer reviewed; Journal article, 2020)Recently, the combination of conventional chemical methods for enhanced oil recovery (EOR) and nanotechnology has received lots of attention. This experimental study explores the dynamic changes in the oil configuration ... -
A paradigm for the evolution of human features: Apes trapped on barren volcanic islands
(Peer reviewed; Journal article, 2020)The aquatic ape hypothesis for human evolution can account for all the traits that distinguish humans from chimpanzees. This scientific paradigm has been considered impossible. It would require that human ancestors maintained ... -
Enhancing oil recovery with hydrophilic polymer-coated silica nanoparticles.
(Peer reviewed; Journal article, 2020)Nanoparticles (NPs) have been proposed for enhanced oil recovery (EOR). The research has demonstrated marvelous effort to realize the mechanisms of nanoparticles EOR. Nevertheless, gaps still exist in terms of understanding ... -
From orogeny to rifting: insights from the Norwegian ‘reactivation phase’
(Peer reviewed; Journal article, 2020)Based on observations from the Mid-Norwegian extensional system, we describe how, when and where the post-Caledonian continental crust evolved from a context of orogenic disintegration to one of continental rifting. We ... -
Anatomy of a mega-rock slide at Forkastningsfjellet, Spitsbergen and its implications for landslide hazard and risk considerations
(Peer reviewed; Journal article, 2019)Rock slope failures are a potential source of danger in polar regions. A causal connection between slope failures and climate-related glacial and deglacial processes has been inferred for the growing number of documented ... -
Estimation of in situ anisotropy parameters from two perpendicular walkaway VSP lines in South Pars field
(Peer reviewed; Journal article, 2019)Vertical phase slowness and polarization angle are the in situ parameters of P-wave propagation that can be derived from walkaway vertical seismic profiling (VSP) data. To use these data for estimating anisotropy parameters, ... -
Non-orthogonal beam coordinate system wave propagation and reverse time migration
(Peer reviewed; Journal article, 2019)Grid size has a significant influence on the computation efficiency and accuracy of finite-difference seismic modeling and can change the workload of reverse time migration (RTM) remarkably. This paper proposes a non-orthogonal ... -
AEM in norway: A review of the coverage, applications and the state of technology
(Peer reviewed; Journal article, 2021)From the first use of airborne electromagnetic (AEM) systems for remote sensing in the 1950s, AEM data acquisition, processing and inversion technology have rapidly developed. Once used extensively for mineral exploration ... -
Segmentation of the Caledonian orogenic infrastructure and exhumation of the Western Gneiss Region during transtensional collapse
(Peer reviewed; Journal article, 2021)The (ultra)high-pressure Western Gneiss Region of the Norwegian Caledonides represents an archetypical orogenic infrastructure of a continent–continent collision zone. To test established exhumation models, we synthesize ... -
Multi-isotope tracing of the 1.3–0.9 Ga evolution of Fennoscandia; crustal growth during the Sveconorwegian orogeny
(Peer reviewed; Journal article, 2021)Magmatism between 1.3 and 0.9 Ga at the southwestern margin of Fennoscandia, comprising mainly granitic batholiths and subordinate bimodal volcanic rocks, provides a nearly continuous magmatic record of the Fennoscandian ... -
1.80–1.75 Ga granite suites in the west Troms Basement Complex, northern Norway: Palaeoproterozoic magma emplacement during advancing accretionary orogeny, from field observations
(Peer reviewed; Journal article, 2022)The Ersfjord Granite is part of a suite of c.1.80–1.75 Ga syeno-granites in the West Troms Basement Complex, northern Norway, presumed to belong to the Transscandinavian Igneous Belt (TIB-1) in the Fennoscandian Shield. ... -
Northern Lights Project: Aurora Model Investigation with Sensitivity Studies and Using Different Simulation Methods
(Master thesis, 2022)The Norwegian "Longship" full-scale carbon capture and storage (CCS) project was defined over the Norwegian Continental Shelf (NCS) following the successful Sleipner CO2 storage operation. The Northern Lights project is ... -
Bevaring av kulturminner i grunnen. En evaluering av grunnforholdene i Midtbyen, Trondheim.
(Master thesis, 2022)Sporene bevart i grunnen etter middelalderbyene i Norge er av svært høy nasjonal verdi. Middelalderbyene har hatt bosetning i over 1000 år. Dette har resultert i akkumulasjonen av tykke kulturlag på til sammen trolig 3,5 ... -
