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 ... -
Diskusjon av opprinnelsen til deformasjonsstrukturane i dalbotnsedimenta i Innfjorden
(Master thesis, 2010)Innfjorden ligg i Møre og Romsdal kommune. Bergartane i område har vore utsett for store trykk- og temperatur på kjenningar under danninga av den kaledonske fjellkjeden. Gjentatte istider har gravd utdalar og fjordar og ... -

Dissolution and carbonation of mechanically activated olivine-Investigating CO2 sequestration possibilities
(Doctoral Theses at NTNU, 1503-8181; 2010:5, Doctoral thesis, 2010)Mineral carbonation used for CO2 sequestration faces three main challenges: increasing the overall carbonation rate, handle large amounts of feedstock and products, and developing a practical process with commercially ... -
Dissolution of CO2 in Aquifer Due to Natural Convection
(Master thesis, 2011)CO2 is the main compound identified as affecting the stability of the Earth’s climate of all greenhouse gases generated globally. It contributes significantly to climate warming and has risen from about 280ppm immediately ... -
Distributed Acoustic Sensing (DAS) As a New Tool For Subsurface Imaging
(Master thesis, 2022)Seismic imaging has been developed through last decades, that it becomes an important tool for subsurface imaging, which is used by various academic and exploration communities, helping them making better decisions when ... -
Distributed acoustic sensing of ocean-bottom seismo-acoustics and distant storms: A case study from Svalbard, Norway
(Peer reviewed; Journal article, 2023)Distributed acoustic sensing (DAS) leverages an ocean-bottom telecommunication fiber-optic cable into a densely sampled array of strain sensors. We demonstrate DAS applications to passive acoustic monitoring (PAM) through ... -
Distribution of Hydrate Inhibitors in Processing of Gas-Condensate
(Master thesis, 2013)The formation of gas hydrates have been known to cause serious problems with blockages in natural gas pipelines, wellbore and natural gas processing units. The offshore sector of the North Sea comes into focus owing to ... -
