(Master thesis / Masteroppgave, 2012)
Seismic data contains reflections along with diffractions. Diffractions in seismic data are related to different features like faults, fractures, pinchouts and rough edges of salt bodies. It follows that suppression of ...
Use of Multiples in VSP Depth Imaging Restricted Access
(Master thesis / Masteroppgave, 2008)
Vertical seismic profiling is a borehole seismic method that provides valuable and reliable information about the local geological structure; with superior resolution compared to surface seismic. The recorded multicomponent ...
(Master thesis / Masteroppgave, 2012)
Glacio-meteorological investigations were conducted on Storbreen glacier, as an attempt to assess the relationship between meteorological conditions at the glacier surface and its mass balance. Primary focus was set on the ...
(Master thesis / Masteroppgave, 2012)
Marine seismic acquisition represents one of the most used geophysical exploration techniques employed in the petroleum industry today. However, one major challenge is that the meaningful part of the data will be distorted ...
(Master thesis / Masteroppgave, 2010)
In a 3D marine survey, often large areas of poor coverage (‘coverage holes’) exist caused by feathering during the actual acquisition. Infill management is introduced to fill those ‘coverage holes’, but a high percentage ...
(Master thesis / Masteroppgave, 2009)
Sea surface profile and reflection coefficient estimates are vital input parameters to various
seismic data processing applications. The common assumption of a flat sea surface when
processing seismic data can lead to ...
A Late Jurassic Boreal echinoderm Lagerstätte from Janusfjellet, central Spitsbergen, Arctic Norway Restricted Access
(Master thesis / Masteroppgave, 2011)
A well preserved, low diversity assemblage of fossil echinoderms is described from the Volgian Slottsmøya Member (Agardhfjellet Formation) on central Spitsbergen. Five species are recognized: the isocrinid Chariocrinus sp. ...
Fossile iskilepolygoner i Finnmark : Utbredelse, dannelse og egenart Restricted Access
(Master thesis / Masteroppgave, 2011)
Fossile iskilepolygoner er kartlagt, beskrevet og datert i Finnmark fylke. Tidligere kartlegginger og observasjoner er samlet, digitalisert og oppdatert. I areal er det nå omtrent et dobbelt så stort område som er registrert ...
(Master thesis / Masteroppgave, 2011)
A newly excavated locality yielding plesiosaurs in the Late Jurassic Slottsmøya Member of the Agardhfjellet Formation, Spitsbergen
shed new light on earlier theories of functional morphology. The propodials of the Slottsmøya ...
(Master thesis / Masteroppgave, 2012)
The main goal of this thesis is to make a detailed lithostratigraphic map of Gressholmen, Rambergøya, Heggholmen and Bleikøya, using an improved topographical database.
Upper Ordovician to Lower Silurian sediments are ...
