(Master thesis / Masteroppgave, 2019)Potential field analysis is known to suffer from the problem of "non-uniqueness" in solutions. Gravity data interpretation is a prime example. Anomalous bodies can be detected from the gravity field, but information regarding ...
-
(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 ...
-
(Master thesis / Masteroppgave, 2021)Fluid flow through low permeability rocks is largely controlled by fractures. As a result, the remote detection and characterisation of fractures is critical for projects involving storage or extraction of fluids. A better ...
-
(Master thesis / Masteroppgave, 2017)The principles of signals from vibrators have been investigated over half a century, however such sources are rarely applied in a marine environment. The objective of this thesis is to study the modeling of the pressure ...

(Master thesis / Masteroppgave, 2020)Diffractions can provide information about small scale heterogeneities. However, in many cases, the diffracted energy is masked by the stronger reflections. Thus, techniques for separating diffractions from reflections are ...
-
(Master thesis / Masteroppgave, 2019)Impact craters are a common geological feature found on a variety of planetary bodies throughout the Solar System and can reveal information about the history of the Solar System and its planets. Specifically, crater ...

(Master thesis / Masteroppgave, 2009)Sammendrag På Åknes i Møre og Romsdal, Norge, er det i dalsiden av en fjord oppdaget et potensielt fjellskred. Et ras på Åknes kan lage en enorm flodbølge nede i fjorden. Denne flodbølgen vil ødelegge de nærmeste bygdene ...
-
(Master thesis / Masteroppgave, 2019)The effects of pore pressure and fluid saturation on the seismic velocity changes are coupled and important to discriminate one from the other in the context of time-lapse monitoring of fluid injection into the subsurface ...
-
(Master thesis / Masteroppgave, 2009)Marin seismic acquisition results in signals that are affected by both random and coherent noise. For successful imaging it is important that as much as possible of this noise is attenuated in an early stage of processing. ...
-
(Master thesis / Masteroppgave, 2012)Scandinavian Mountain Range is located at the continental margin of the Eurasian plate. This area is part of the Baltic shield so topography is expected to be generally low. But this is not the case here. In South western ...
-
(Master thesis / Masteroppgave, 2011)Abstract Seismic time migration is a cost and time effective process for imaging of the subsurface. However, the approach is traditionally limited to velocity models with mildly varying lateral variations. The objective ...
-
(Master thesis / Masteroppgave, 2013)In this thesis a new approach, called THEAMTM, is presented. The THEAMTM methodology is a non-invasive tunnel health monitoring method using active seismic. The method incorporates geophysical seismic analysis methods and ...
-
(Master thesis / Masteroppgave, 2013)Marine Seismic Interference (SI) occurs when several seismic vessels operate in close proximity, and the interfering energy from one vessel is recorded as interfering noise by another. Generally, SI is removed by various ...

(Master thesis / Masteroppgave, 2013)Two wide angle 3-Compnent Ocean Bottom Seismometer (OBS) profiles along with associated Land-Stations acquired during 2003 under the EUROMARGINS Program were analyzed during this M.Sc. Thesis. These profiles are named as ...
