Magnetization of exsolution intergrowths of hematite and ilmenite: Mineral chemistry, phase relations, and magnetic properties of hemo-ilmenite ores with micron- to nanometer-scale lamellae from Allard Lake, Quebec
(Journal article; Peer reviewed, 2007)[1] Hemo‐ilmenite ores from Allard Lake, Quebec, were first studied over 50 years ago. Interest was renewed in these coarsely exsolved oxides, based on the theory of lamellar magnetism as an explanation for the high and ... -
Main aspects of deformation and rock support in Norwegian road tunnels
(Journal article; Peer reviewed, 2019)The general geology of Norway makes most of its tunnels to be constructed mainly in strong rock intersected by weakness zones of different sizes and characteristics. The Norwegian support tradition is, to the largest degree ... -
Maintaining well integrity during slot recovery operations
(Master thesis, 2012)The temporary plug and abandonment (P&A) of old wells, and the following slot recovery, will be important for increasing the average rate of recovery from the Norwegian Continental Shelf (NCS). However, these operations ... -
Maintenance And Renewal Optimization Of Electric Power Supply In Railways
(Master thesis, 2010)This report is written for JBV (Norwegian Railway Administration). The motivation for this topic arose from deteriorating electric power converter station. The impact of failure is in terms of train cancelations and delays. ... -
Managed Pressure Cementing - Simulations of Pressure and Flow Dynamics During Cementing Using Applied Back-Pressure and Dual Gradient
(Master thesis, 2017)Cement operations in narrow pressure windows can be challenging, due to the increased hydrostatic pressure caused by heavy-weight cement. Through managed pressure control, downhole pressure fluctuations can be controlled, ... -
Managed Pressure Drilling: The Solaris Prospect - HPHT Exploration well
(Master thesis, 2013)Managed Pressure Drilling is a drilling technique that evolves continuously. Complex drilling problems such as narrow mud-weight windows (narrow pressure margins), severe losses and deep water effects can be significantly ... -
Management of a High Arctic River - Erosion and Sediment Transport in Longyearelva, Svalbard
(Master thesis, 2021)Som en konsekvens av økende fokus på geofarer gjennomføres en storstilt omstilling av infrastruktur og boligmasser i Longyearbyen, Svalbard (78⁰13’N, 15⁰38’E). Permanent erosjon- og flomsikring av Longyearelva ble ferdigstilt ... -
Management of Drilling Fluid Circulation
(Master thesis, 2010)To maintain the safety of well control operation, especially for the prevention of uncontrolled blowouts, early kick detection is extremely important in the drilling rigs. From very early stage of rig operation, a sudden ... -
Managing pressure during underbalanced drilling
(Master thesis, 2012)AbstractUnderbalanced drilling has received more and more attention in recent years. The reason for that may be because many oil fields, especially on the Norwegian continental shelf, have started to show signs of aging. ... -
Mandalsvassdraget - optimalisering av tunnelsystem med hensyn til ingeniørgeologiske forhold
(Master thesis, 2019)I det tverrfaglige forskningprosjektet «AlternaFuture» benyttes Mandalsvassdraget til forskning på ekstrem ombygging av et eksisterende vannkraftsystem. Dette skal kombineres med å forbedre miljøforholdene i vassdraget. ... -
MAP MIGRATION OF THE PANDORA DIAPIR IN THE NORDKAPP BASIN, BARENTS SEA
(Master thesis, 2011)Seismic imaging in the Nordkapp Basin in the Barents Sea involves many problems, which are not easily solved with conventional imaging methods. The basin has complex geometry as it consists of several salt structures. The ... -
Mapping and modelling mineral sources of natural remanent magnetization from the Russell Belt microcline-sillimanite gneiss, Northwest Adirondack Mountains, USA
(Peer reviewed; Journal article, 2021)Distinct crustal remanent magnetic anomalies are a strong indicator of rocks with stable natural remanent magnetization (NRM) carriers. The latter are able to store information on the history of a rock over long geological ... -
Mapping magnetic sources at the millimeter to micrometer scale in dunite and serpentinite by high-resolution magnetic microscopy
(Journal article; Peer reviewed, 2018)Rock samples can have wide range of magnetic properties depending on composition, amount of ferromagnetic minerals, grain sizes and microstructures. Here, we used scanning magnetic microscopy, a highly sensitive and ... -
Mapping of gravitational deformation at Redfjellet, western Norway, and its relation to the tectonic history
(Master thesis, 2021)Opp gjennom historien har fjellskred og sekundære effekter som flodbølger gjentatte ganger utgjort en fare mot samfunnet i Norge. Flere katastrofale hendelser har ført til totalt 932 omkomne, noe som underbygger behovet ... -
Mapping of shallow Tunnel Valleys combining 2D and 3D Seismic Data
(Master thesis, 2012)In this study 19 tunnel valleys within block 2/4 in the central North Sea basin have been mapped. Furthermore, the possibility for these valleys to act as migration paths for leaked gas has been evaluated. In January 1989 ... -
Mapping of Shrinkage Cracks with Dye Penetrant on Sprayed Concrete Cores
(Master thesis, 2020)Ein ny metode for kartlegging av svinnriss på sprøytebetongkjernar blei testa i denne masteroppgåva. Dette vart gjort med penetrantvæske med fargemiddel. Metoden er ein ikkje-destruktiv test metode på sprøytebetongkjernar. ... -
Mapping Reservoir Changes Using 4D Seismic on the Norne G-segment, Norwegian Sea
(Master thesis, 2013)Time-lapse seismic can be an important tool for monitoring and planing further development of a producing hydrocarbon field. Use of 4D seismic can make itpossible to detect production changes over a relatively large area ... -

Marine palaeoproductivity in the Blodøks Formation of the North Sea.
(Master thesis, 2015)Marine palaeoproductivity will be determined from measured values using core data from the Cretaceous Blodøks Formation and its equivalent formation in the Norwegian Sea. Data needed for such calculations included total ... -
