Modeling and Inversion of CSEM Data using Green's Function Methods
(The University of Bergen, 2014-06-01)
The aim of the present study is to develop new approximations to the integral equation for 3D Controlled Source Electromagnetic (CSEM) synthetic data. Several scattering approximations to the integral equation have previously ...
Structural analysis of the Jebel Fadeloun anticline, Tunisia: Impact of fractures and faults on the petrophysical properties of carbonate rocks
(The University of Bergen, 2015-06-01)
Recognizing the structure, evolution and fluid flow within the earth's crust is a critical issue for both academic and applied geoscience. This study presents structural analysis of an anticline, which aim is to elucidate ...
Gravity modeling: Calculations based on porosity-density context
(The University of Bergen, 2010-06-17)
A normal way to model the gravity from a layered model is to determine the densities from the velocities, and then adjusting the densities within acceptable ranges to get a satisfactory fit with the observed gravity. In ...
Physical and Chemical Processes in the Bjerkreim-Sokndal Magma Chamber
(The University of Bergen, 2010-03-19)
Deformation of sandstone reservoirs. Insight from experiments and field studies
(The University of Bergen, 2014-09-18)
Tectonostratigraphic evolution of a multi-episodic rift. The northern Norway - Greenland rift: from post-orogenic exhumation to deep marine turbidites
(The University of Bergen, 2015)
The aim of this project is to improve the tectonostratigraphic understanding of the northern part of the Norwegian passive continental margin, the so-called Lofoten margin, and contribute to the wider understanding of ...
Dissolved gases in hydrothermal plumes from Artic vent fields
(The University of Bergen, 2013-10-30)
Recent discoveries of active vent fields on slow and ultraslow spreading ridges have revealed that hydrothermal activity is more common than previously assumed. In the Norwegian-Greenland Sea, two such vent fields are ...
Exploring the Microseismicity of the Gakkel Ridge from Arctic Sea Ice
(The University of Bergen, 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, ...
Isotopic composition of Pb in tree rings of Norway spruce (Picea abies) from the Fensfjorden area, western Norway
(The University of Bergen, 2012-06-01)
The annual growth of tree rings makes the trees as possible archive of the past atmospheric pollution. However, several aspects addressed in literature such as post-depositional mobility of Pb, intra-ring heterogeneity ...
Rock physics and seismic AVA analysis of gas hydrate-bearing sediments
(The University of Bergen, 2014-06-02)
Large amount of natural gas are present in submarine sediments and permafrost areas in the form of gas hydrates. Gas hydrates are a large potential future energy resource, and may contribute to the methane balance in the ...
