(Master thesis, 2011)Mineralization of molybdenite were discovered in the Kleivan granite, Lyngdal and document that the ore-forming potential of this rare example of a differentiated, A-type, granite. The cryptic zonation up through the igneous ... -
Monitoring Overburden and Reservoir Changes from Prestack Time-Lapse Seismic Data: Applications to Chalk Fields
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:37, Doctoral thesis, 2007)Reservoir compaction due to hydrocarbon production has been observed in several North Sea reservoirs, especially the chalk reservoirs in the southern part. This compaction leads to changes in porosity and permeabilities ... -
Morphometric analysis of sediment conduits on a bathymetric high: Implications for palaeoenvironment and hydrocarbon prospectivity
(Journal article; Peer reviewed, 2018)Canyons and other sediment conduits are important components of the deep-water environment and are the main pathways for sediment transport from the shelf to the basin floor. Using 3-D and 2-D seismic reflection data, ... -
MPD Case and Trend-Study Operational Time Analysis
(Master thesis, 2011)Managed Pressure Drilling (MPD) is a pressure control and management-technology that has been around for over a decade and that is believed by service providers to have the potential of highly in-creased use in the future. ... -
MPD Heave Lab: CBHP Simulations and Hydraulic Analysis
(Master thesis, 2013)Drilling performed from floating drilling rigs subjected to heave motion may be challenging. As the drillstring is suspended in slips during connection, the entire drillstring follows the motion of the floating rig. In ... -
MRST Vertical Equilibrium Model analysis for CO2 Storage
(Master thesis, 2023)Hovedformålet med denne studien er å importere Aurora-modellen, som er utviklet ved Universitetet i Oslo i samarbeid med Gassnova og Ross Offshore, inn i MATLAB Reservoir Simulation Toolbox (MRST) for å anvende funksjonen ... -
Multi-criteria studies and assessment supporting the selection of locations and technologies used in co2-egs systems
(Peer reviewed; Journal article, 2021)The paper describes application of the cross-impact method in the process of selecting locations and technologies used in a geothermal system based on energy accumulated in a dry rock formation, where CO2 is used as the ... -
Multi-dimensional semi-analytical model for axial stick?slip of a rod sliding on a surface with Coulomb friction
(Journal article; Peer reviewed, 2019)A multi-dimensional lumped element model of a long non-rotating rod that moves on a slick surface with both dynamic and static Coulomb friction is outlined. The rod is accelerated to a constant velocity, and the free end ... -
Multi-isotope tracing of the 1.3–0.9 Ga evolution of Fennoscandia; crustal growth during the Sveconorwegian orogeny
(Peer reviewed; Journal article, 2021)Magmatism between 1.3 and 0.9 Ga at the southwestern margin of Fennoscandia, comprising mainly granitic batholiths and subordinate bimodal volcanic rocks, provides a nearly continuous magmatic record of the Fennoscandian ... -
