(Master thesis, 2023)Utforming av bergskjæringer langs offentlig vei skal følge krav i Statens vegvesens håndbok N200 Vegbygging. Håndbok N200 har hjemmel i vegloven, og deler av håndboken er bygd opp på grunnlag av den europeiske standarden ... -
Hydrogeologiske forhold på Svelvik CO2 feltlaboratorium og ved Svelvikryggen - Med fokus på grunnvannsstrømning i RS2, tidevannsforhold og vannkjemi
(Master thesis, 2023)Svelvikryggen er en glasifluvial avsetning som ligger i Drammensfjorden ved Svelvik. Over den åpne og den lukkede akviferen på Svelvikryggen befinner det seg i dag et CO2 feltlaboratorium som SINTEF eier. Der forskes det ... -
Geomechanics and Rock Physics of Anisotropic Overburden Shales
(Doctoral theses at NTNU;2023:326, Doctoral thesis, 2023)Shales, with their diverse composition and complex properties, present an interesting research subject and a challenging material to work with. As they constitute a significant portion of the overburden in most currently ... -
The northern Vøring outer ridges complex: new structural and sedimentary constraints
(Master thesis, 2023)Denne masteroppgaven fokuserer på å finne nye strukturelle og sedimentære avgrensninger for geometrien til Nykhøyden som ligger i den ytre delen av Vøringbassenget; en del av den midtnorske riftmarginen. Gjennom dette ... -

Capillary washboarding during slow drainage of a frictional fluid
(Peer reviewed; Journal article, 2023)Numerous natural and industrial processes involve the mixed displacement of liquids, gases and granular materials through confining structures. However, understanding such three-phase flows remains a formidable challenge, ... -
ETP SMR Strategic Research and Innovation Agenda (SRIA)
(Research report, 2023)Officially recognized by the European Commission in 2008, ETP SMR successfully combines interdisciplinarity and deep commitment from its members. Its significance is underlined by the increasing political and strategic ... -
Optimizing the Rate Balance Between Multiple CO2 Injectors for the Aurora Storage Site
(Master thesis, 2023)Den globale utfordringen med å redusere klimagassutslipp har nødvendiggjort utviklingen av effektive strategier for fangst og lagring av karbon (CCS). Denne oppgaven fokuserer på optimalisering av CO2-injeksjonsoperasjonen ... -
Full-scale pullout tests of rock anchors in a limestone quarry focusing on bond failure at the anchor-grout and grout-rock interfaces
(Peer reviewed; Journal article, 2023)Rock anchors are a common safety measure for stabilising large-scale infrastructure, such as bridge towers, retaining walls, rock slopes and windmills. There are four principal failure modes for rock anchors: (a) tensile ... -
Bayesian rock physics inversion using a localized ensemble-based approach - with an application to the Alvheim field
(Peer reviewed; Journal article, 2023)We describe, implement and show results of a localized ensemble-based approach for seismic AVO inversion with uncertainty quantification. Ensembles are simulated from continuous prior probability distributions for fluid ... -
Inclusion of advection in fractures in the line source equation for analysis of thermal response tests
(Peer reviewed; Journal article, 2024)Proper design of larger ground source heat pump installations, and borehole thermal energy storages (BTES) requires determination of on-site thermal properties of the ground by performing a thermal response test (TRT). The ... -
Design of a test facility for oil-water separation and water treatment
