Diagenesis and Reservoir Quality of the Hugin Formation Sandstones in the North Sea: A Petrographical Approach
(Master thesis, 2013)The Middle Jurassic Hugin Formation in the Sleipner area has been studied in five wells in the southern Viking Graben in the Norwegian sector of the North Sea. The main objective is to understand how the diagenetic development ... -
Diagenesis and reservoir quality preserving mechanism in the deeply buried Lower to Middle Jurassic Formation in the Halten Terrace, offshore Mid-Norway.
(Master thesis, 2022)Heterolittiske sandsteinsreservoar fra Haltenterrassen har blitt undersøkt for å se på innvirkningen av diagenese på reservoarkvaliteten. For dette studiet har det blitt brukt 27 polerte tynnslip med blå epoxy farging fra ... -
Diagnosing Root Causes and Generating Graphical Explanations by Integrating Temporal Causal Reasoning and CBR
(Journal article; Peer reviewed, 2017)This study proposes a methodology to diagnose the root causes of failures in the domain of oil well drilling. The idea is to combine a Bayesian network, which is generated based on an expert knowledge, with situation-specific ... -
Different aspects of detecting karst with geophysical methods - Tales from the underworld
(Doctoral theses at NTNU;2020:406, Doctoral thesis, 2020)The work in this thesis integrate conventional seismic interpretation, gravity survey data, field data from analogues and state-of-the-art numerical modeling in order to broaden and increase the understanding of the ... -
Differential evolution for early-phase offshore oilfield design considering uncertainties in initial oil-in-place and well productivity
(Peer reviewed; Journal article, 2021)During the early phases of offshore oil field development, field planners must decide upon general design features such as the required number of wells and maximum oil processing capacity (field plateau rate), usually by ... -

A digital approach to modeling tubular wear and its effects on well integrity
(Doctoral theses at NTNU;2022:122, Doctoral thesis, 2022)Drilling of wells for exploration and production of petroleum resources requires thorough analysis of well integrity. Well integrity can be defined as the application of technical, operational and organizational solutions ... -
Digital kartlegging og 3D modellering av en geologisk forekomst
(Master thesis, 2012)I denne oppgaven presenteres teknologiske løsninger og arbeidsmetoder for utredningen av en skiferforekomst utenfor Sandane i Sogn og Fjordane. Forekomsten har store geologiske variasjoner, hvilket fører til problemer ved ... -
Digital well planning - Well Intervention
(Master thesis, 2021)Dagens olje og gass industrien har sett en formidabel fremgang i teknologi og utstyr som er nødvendig for å kunne gjennomføre stadig mer krevende brønnintervensjoner. Brønnplanleggingsprosessen har ikke sett den samme ... -
Digital Well Planning for Completions
(Master thesis, 2021)Den nåværende planleggingsprosessen for brønnkomplettering er i de fleste operatørselskaper en manuell prosess som involverer praktisk tilnærming trinn for trinn. Det er preget av gjentatte beregninger, møter og utveksling ... -
Digital Well Planning: Next Generation Workflow
(Master thesis, 2022)Petroleumsnæringen er inne i en periode med høyt fokus på digitalisering og automatisering. Dette fokuset er spesielt drevet av en ambisjon om å redusere kostnader, effektivisere drift og øke sikkerheten. Flere nye ... -

Digitalization and Automation of Plug and Abandonment Operations
(Master thesis, 2022)In this thesis, the principles to design and implement software application to fully automate the Plug and Abandonment operations is discussed. The application is planned to be developed to enter the data manually from new ... -
Dipole and Nondipole Evolution of the Historical Geomagnetic Field From Instrumental, Archeomagnetic, and Volcanic Data
(Peer reviewed; Journal article, 2021)Although a large number of magnetic declination and inclination measurements are available for the historical period from 1400 to 1900 CE, even the evolution of the axial dipole moment, the most prominent quantity of the ... -
Directional Drilling - Advanced Trajectory Modelling
(Master thesis, 2014)SummaryDrilling operations are a significant cost in the process of recovering hydrocarbons. The operations are advanced and associated with large HSE and financial risks. The main objectives in a successful drilling ... -
Direkte fundamentering på berg
(Master thesis, 2020)Direkte fundamentering på berg er et tema som er viet lite oppmerksomhet. Oppgaven er et bidrag i retningen av økt fokus og forbedret praksis. Det er gjort analyser av samvirket mellom fundament og berg for å utarbeide ... -
Discovery of distinct lithosphere-asthenosphere boundary and the Gutenberg discontinuity in the Atlantic Ocean
(Peer reviewed; Journal article, 2022)The plate tectonic theory requires a rigid lithosphere floating over a weak asthenosphere, separated by the lithosphere-asthenosphere boundary, which has been sometimes interpreted as the Gutenberg discontinuity. Using a ... -
Discussions on rockburst and dynamic ground support in deep mines
(Peer reviewed; Journal article, 2019)The paper is a summary of discussions on four topics in rockburst and dynamic ground support. Topic1 is the mechanisms of rockburst. Rockburst events are classified into two categories in accordancewith the triggering ... -
