Petrography, geochemistry and sedimentology of sandstones from the Central Tertiary Basin of Svalbard – implications for diagenesis and temperature history
(Master thesis, 2019-10-03)Svalbard, representing an uplifted area of the north-western Barents Sea Shelf, provides a unique opportunity for studying on-shore outcrops of the shelf. The present study focuses on Paleocene-Eocene deposits of the Central ... -
The Petroleum Systems of the South Viking Graben, Norway
(Doctoral thesis, 2006-05-05) -
Petroleum, coal and research drilling onshore Svalbard: a historical perspective
(Peer reviewed; Journal article, 2019)The beginning of the Norwegian oil industry is often attributed to the first exploration drilling in the North Sea in 1966, the first discovery in 1967 and the discovery of the supergiant Ekofisk field in 1969. However, ... -
Petrology and Provenance of the Upper Cretaceous Strata in Central Utah
(Master thesis, 2015-06-01)The reservoir quality of sandstones is primarily controlled by the primary composition of the rock volume and the effects of later diagenetic processes. Much work has been done to improve the understanding of diagenetic ... -
Petrophysical properties of deformation bands and their influence on fluid flow in carbonate grainstones: insights from the Maghlaq Fault, Malta.
(Master thesis, 2015-06-08)Deformation bands are tabular, sub- centimeter thick zones, which accommodates shear and/or volumetric deformation. Only a few examples of deformation bands have been documented in porous carbonate rocks, and the knowledge ... -
Petrophysical Properties of Deformed Sandstone Reservoir
(Master thesis, 2012-06-21)Small scale deformation structures that mostly occur in highly porous rocks are called deformation bands. Petrophysical characteristics of deformation bands are different from those of host rock and they can act as barriers ... -

Physical modelling of the interplay between salt-detached gravity gliding and spreading across complex rift topography, Santos Basin, offshore Brazil
(Journal article; Peer reviewed, 2022)The Santos Basin, offshore Brazil contains a complex set of salt-tectonic structures, the origins of which are debated, that is, the Albian Gap and the São Paulo Plateau (SPP). The Albian Gap is a ca. 450 km long, 60 km ... -
Plaster modelling of fault development and geometry in contractional settings
(Master thesis, 2015-06-01)The aim of this study has been to analyse the development of contractional structures using analogue plaster models. Structures similar to natural fault systems are generated using plaster of Paris as the deforming medium ... -
Plaster modelling of fault development in extensional regimes
(Master thesis, 2015-05-31)The full complexity of deformation in natural extensional regimes is complicated, as direct observation in nature is limited in regards to outcrops and structural evolution over time. The aim of this thesis is to analyse ... -
Pleistocene vertical carbon isotope and carbonate gradients in the South Atlantic sector of the Southern Ocean
(Peer reviewed; Journal article, 2003-01-10)We demonstrate that the carbon isotopic signal of mid-depth waters evolved differently from deep waters in the South Atlantic sector of the Southern Ocean during the Pleistocene. Deep sites (>3700 m) exhibit large ... -
Pliocene sea ice evolution in the Iceland and Labrador Sea – A biomarker approach
(Doctoral thesis, 2017-12-07)Sea ice plays a crucial role in the climate system. Although this is broadly acknowledged, the role of sea ice is not fully understood, especially during warmer periods such as the Pliocene (5.88–2.58 Million years ... -
Plume–MOR decoupling and the timing of India–Eurasia collision
(Journal article; Peer reviewed, 2022)The debatable timing of India–Eurasia collision is based on geologic, stratigraphic, kinematic, and tectonic evidence. However, the collision event disturbed persistent processes, and the timing of disturbance in such ... -
The PMIP4 contribution to CMIP6 – Part 4: Scientific objectives and experimental design of the PMIP4-CMIP6 Last Glacial Maximum experiments and PMIP4 sensitivity experiments
(Peer reviewed; Journal article, 2017)The Last Glacial Maximum (LGM, 21 000 years ago) is one of the suite of paleoclimate simulations included in the current phase of the Coupled Model Intercomparison Project (CMIP6). It is an interval when insolation was ... -
Pockmarks i indre Aurlandsfjorden: Aktive eller inaktive lekkasjestrukturer Dannelse, alder og biogeokjemiske prosesser
(Master thesis, 2022-03-07)Ved bruk av høyoppløselige batymetris data er det i indre Aurlandsfjorden, Vest-Norge, kartlagt et område på c. 1.2 km2, på vanndyp mellom 40-72 m.u.h. hvor det er identifisert minst 18 pockmark strukturer. De har en ... -
Point-spread function convolution to simulate prestack depth migrated images: A validation study
(Journal article; Peer reviewed, 2021)Seismic migration commonly yields an incomplete reconstruction of the Earth model due to restricted survey aperture, band-limited frequency content and propagation effects. This affects both illumination and resolution of ... -
Polygonal faults in the northern North Sea
(Master thesis, 2021-06-01)Polygonal faults have been studied in sedimentary basins at the Norwegian continental shelf and globally as non-tectonic normal faults. The polygonal faults have been recognized for a long time, but no one has described ... -
Polygonalforkastninger - karakteristikk og dannelsesmekanismer. En studie basert på tolking av seismiske data fra Norske-Barentshavsmarginen
(Master thesis, 2014-09-22)Polygonale forkastningssystemer (PFS) er bemerkelsesverdige strukturer som er identifisert i en rekke sedimentære bassenger over hele verden. Polygonalforkastninger er normalforkastninger med små sprang som hovedsakelig ... -
