(Master thesis, 2021)Nordkappbassenget er plassert i det sørøstlige Barentshavet utenfor Norge og ble dannet da det norske-grønnlandshavet og Eurasiabassenget åpnet seg.Nordkappbassenger inneholder flere saltstrukturer men distribusjonen ... -
Paleosols in the Triassic De Geerdalen and Snadd formations
(Master thesis, 2015)Parts of the Late Triassic De Geerdalen Formation and the Middle to Late Triassic Snadd Formation have been investigated through facies analysis of outcrop and core data. The purpose has been to identify paleosols, relate ... -
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 ... -
Parameter Detection in real time Drilling Data - Create a Matlab agent to forecast changes in formation hardness
(Master thesis, 2017)Nowadays, being cost efficient is a major issue of the oil and gas sector. Reducing Non Productive Time (NPT) is one of the solutions to tackle this challenge. As a result, the industry is always looking for more solutions ... -
Parameter Study for Mobility of Rock Avalanches and Rock Collapses in Western Norway.
(Master thesis, 2023)I hvilken grad enkelte parametere som bergart, substrat og topografi påvirker mobiliteten til fjellskred («Rock collapse» og «Rock avalanche») er ikke velstudert. To nylige skredhendelser i de europeiske alpene, «Flücthorn ... -
Particle scale reservoir mechanics
(Doktoravhandlinger ved NTNU, 1503-8181; 116, Doctoral thesis, 2002)When a petroleum reservoir is produced, the mechanical state of stress is changing, which leads to alteration of rock mechanical behaviour, of fluid flow, and of geophysical parameters. Numerical schemes have been developed ... -

Past slope collapse and current unstable slopes along a cliff at Hyllestad Kommune
(Master thesis, 2018)With the aim of a complete national database of potential unstable slopes, the Geological Survey of Norway currently carries out systematic geological mapping of rock slopes organized in counties. As part of the survey of ... -
Pavement wear and airborne dust pollution in Norway
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:133, Doctoral thesis, 2008)In several large cities in Norway the traffic volume is high. The use of studded tires and other friction enhancing measures during winter leads to significant pavement wear, which in turn leads to an increase in the amount ... -
Påvirkning av avsetningsmiljø og diagenese på reservoarkvalitet i reservoarerer fra trias på Trøndelagsplattformen og Ellingråsagrabenen
(Master thesis, 2019)Formålet med denne masteroppgaven har vært å avgjøre hvordan avsetningsmiljø og diagenese påvirker reservoarkvaliteten i reservoarer fra trias på Trøndelagsplattformen og i Ellingråsagrabenen. Hvordan evaporitter fra trias ... -
