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 ... -
3D Joint Inversion of Scanning Magnetic Microscopy Data
(Journal article; Peer reviewed, 2021)Scanning magnetic microscopy (SMM) is a modern magnetometry technique that maps the magnetic anomalies resulting from small-scale variations of remanent magnetization within a sample. This information is vital to understand ... -
3D Numerical Modeling of Rock Mass Failure in an Uplift Test of a Rock Anchor with Focus on the Role of Rock Joints
(Journal article; Peer reviewed, 2025)This paper aims to numerically study the failure mechanisms of the rock mass during the uplift test of a rock anchor installed in limestone. The rock anchor consisted of a smooth tendon, with short threaded sections at ... -
3D seismic analysis of salt tectonics and depositional systems in the Kwanza Basin (offshore Angola): from basin dynamics to geohazard analysis
(Master thesis, 2012)This thesis uses the combination of 2D and 3D seismic data and seismic attributes to investigate and understand the interaction between the salt tectonics and depositional systems in the Kwanza Basin (offshore Angola-block ... -
3D Seismic Interpretation and Evaluation of Survey Area SG9803, Caurus Prospect, SW Barents Sea
(Master thesis, 2013)3D seismic survey SG9803 was carried out in 1998 in the south-western Barents Sea. On the basis of 3D seismic data a wildcat well 7222/11-1 in platform area of Loppa High was drilled in 2008. This prospect is called Caurus. ... -
3D seismic interpretation in a deep-marine depositional environment from Lower Congo Basin offshore Angola
(Master thesis, 2013)3D seismic data from the offshore Congo Basin, Angola has been performed in order to do geological interpretation of deep-marine deposits and understand the depositional system in the basin. Architectural elements, such ... -
3D seismic interpretation in a deep-water depositional environment from Lower Congo Basin
(Master thesis, 2013)This Master of Science (M.Sc.) thesis focuses on the detailed characterization and interpretation of deep-water depositional system within Lower Congo Basin, offshore Angola. The application of seismic geomorphology has ... -
3D seismic interpretation of the depositional morphology of the Middle to Late Triassic fluvial system in Eastern Hammerfest Basin, Barents Sea
(Journal article; Peer reviewed, 2015)Integration of seismic, well and outcrop analog data provided realistic definition of the depositional morphology of the Snadd Formation in the Eastern Hammerfest Basin, Barents Sea. In this work the morphology of the ... -
3D Seismic Modelling of Thin Intrusions
(Master thesis, 2014)This study presents seismic modeling of two intrusions, modeled as boreholes.The modeling was done over homogenous one-layered models in both 2D and 3D,and a two-layered model in 3D. The goal of the study was to see if ... -
3D-geologisk modellering og inndriftsestimering av utvalgte deler av Krokskogtunnelen
(Master thesis, 2020)På veien mot en papirløs arbeidsplass spiller BIM-modellering en sentral rolle. En 3D-geologisk modell over antatt bergmassefordeling mot dypet er et av elementene som er vanlig å inkludere i en BIM-modell. I denne ... -
3D-modellering av bergmasse og stabilitetsvurdering av planlagt tunnel ved E6 Langnesberga
(Master thesis, 2024)E6 forbi Langnesberga har blitt identifisert av Meld. St. 14 (2023–2024) (2024) som et av de mest skredutsatte veiene i Trøndelag. Det er besluttet å bygge en tunnel gjennom Langnesberga for å unngå denne eksponeringen. ... -
