Experimental investigation of deformation mechanisms during shear-enhanced compaction in poorly lithified sandstone and sand
(Peer reviewed; Journal article, 2013-08-27)Shear-enhanced compaction in shallow sandstone reservoirs has been investigated in laboratory experiments using high-pressure triaxial testing of poorly lithified sandstone and sand. We have studied the deformation mechanism ... -
Experimental investigations of Magnetization processes in Chinese loess
(Doctoral thesis, 2011-11-25) -
An experimental study of the effect of water and chlorine on plagioclase nucleation and growth in mafic magmas: application to mafic pegmatites
(Journal article; Peer reviewed, 2023)In this study, the effects of H2O and Cl on the grain size and nucleation delay of plagioclase in basaltic magma were investigated using dynamic and equilibrium experiments at 1150 ∘C, 300 MPa, and oxygen fugacity between ... -
Exploring seismic detection and resolution thresholds of fault zones and gas seeps in the shallow subsurface using seismic modelling
(Journal article; Peer reviewed, 2022)Seismic resolution and illumination issues are sources of challenges in the detailed imaging and detection of subsurface fault architecture and fluid migration. Improved constraints on resolution can provide input into ... -
Exploring the Microseismicity of the Gakkel Ridge from Arctic Sea Ice
(Master thesis, 2013-06-03)Monitoring of microseismicity is an important tool to understand the magmatism, tectonics and hydrothermal circulation of a mid-oceanic ridge. In the presence of sea ice, use of ocean bottom seismometers is not practical, ... -
Extending local magnitude ML to short distances
(Peer reviewed; Journal article, 2019)Local magnitudes calculated at stations less than 10 km from earthquakes in the British Isles are up to one unit of magnitude higher than local magnitudes calculated at more distant stations. This causes a considerable ... -
Extensional inheritance and surface processes as controlling factors of mountain belt structure
(Peer reviewed; Journal article, 2014-12)Surface processes and inherited structures are widely regarded as factors that strongly influence the evolution of mountain belts. The first-order effects of these parameters have been studied extensively throughout the ... -
Extent and Volume of Lava Flows Erupted at 9°50′N, East Pacific Rise in 2005–2006 From Autonomous Underwater Vehicle Surveys
(Journal article; Peer reviewed, 2022)Seafloor volcanic eruptions are difficult to directly observe due to lengthy eruption cycles and the remote location of mid-ocean ridges. Volcanic eruptions in 2005–2006 at 9°50′N on the East Pacific Rise have been well ... -
Facies Analysis and Sandbody Geometry of the Paleogene Battfjellet Formation, Central Western Nordenskiöld Land, Spitsbergen
(Master thesis, 2010)New sedimentological data from the central part of Nordenskiöld Land, Spitsbergen, contributes to the understanding of the depositional processes and sandbody geometry of the Battfjellet Formation (Eocene). A detailed ... -
Facies and sedimentary architectures in the Upper Silurian Ringerike Group, Eastern Norway
(Master thesis, 2022-06-01) -
Facies Architecture and Paleogeography of the Battfjellet Formation, Rypefjellet, Spitsbergen
(Master thesis, 2010-06-01)The shallow marine sandstones of the Battfjellet Fm are part of a regressive mega-sequence that represent the last stages of infilling of the Paleogene Central Basin in Spitsbergen. The Battfjellet Fm is believed to be of ... -
Facies composition and scaling of extensional faults in sedimentary rocks and its applications to modelling of fault zones
(Doctoral thesis, 2010-01-08) -
Facies model for a coarse-grained, tide-influenced delta: Gule Horn Formation (Early Jurassic), Jameson Land, Greenland
(Peer reviewed; Journal article, 2016-05-25)Tide-dominated deltas have an inherently complex distribution of heterogeneities on several different scales, and are less well-understood than their wave- and river-dominated counterparts. Depositional models of these ... -
Facies, Geometry and Paleogeography of the Eocene Battfjellet Formation, Longyearbyen Area, Svalbard
(Master thesis, 2022-06-01)This MSc thesis investigates the facies and architecture variability of the Paleogene Battfjellet Formation in the Longyearbyen area on Svalbard, with the aim to complement the regional framework of the formation. Together ... -
Facies, palynostratigraphy and sequence stratigraphy of the Wilhelmøya Subgroup (Upper Triassic–Middle Jurassic) in western central Spitsbergen, Svalbard
(Peer reviewed; Journal article, 2019)The Wilhelmøya Subgroup (Norian–Bathonian) is considered as the prime storage unit for locally produced CO2 in Longyearbyen on the Arctic archipelago of Svalbard. We here present new drillcore and outcrop data and refined ... -

Fault core and its geostatistical analysis: Insight into the fault core thickness and fault displacement
(Master thesis, 2017-06-23)Fault core is a high-strain zone of a fault, which accommodate intense deformation. Due to high strain, complex structures and intensely deformed fault rocks form in the fault core, which again affects the geometry and ... -
Fault core thickness: Insights from siliciclastic and carbonate rocks
(Peer reviewed; Journal article, 2019-06-02)Fault core accommodates intense deformation in the form of slip surfaces and fault rocks such as fault gouge, cataclasite, breccia, lenses, shale smear, and diagenetic features. The complexity and variation in fault core ... -

Fault Facies Modelling: 3D representation of faults in petroleum reservoirs
(Master thesis, 2008-06-30)The purpose of a reservoir model is to act as a tool for optimizing development and production strategies for subsurface hydrocarbon reservoirs. Such a model is intended to be predictive, and to act as a map for the ones ...
