Study of the impact of heterogeneity on the modeling of fluid-flow, based on a turbidite reservoir analogue Ainsa-1 quarry outcrop, Spain
(The University of Bergen, 2012-06-01)
Geological heterogeneity includes variations in porosity, lithology, mechanical properties, structure, etc. (Eaton, 2006) and in the case of sedimentary bodies, facies distribution acts as a constraint of them. It is proven ...
Seismiske bølger i havis
(The University of Bergen, 2015-03-23)
Seismiske innsamlinger på havis gir under gitte forhold opphav til kildeinduserte fleksurbølger, og dette problemet oppstår når seismisk energi blir fanget mellom grenseflatene is-luft og is-vann. Fleksurbølgen kan ...
Seismo-tectonics around Lhasa, Tibet
(The University of Bergen, 2011-05-18)
In this thesis I have described the seismic-tectonics of the Tibetan Plateau and around Lhasa as well as introduced the basic situation of seismic stations in Tibet. The focal mechanism, seismic moment and the source depth ...
Re-evaluation and extension of the Marine Isotope Stage 5 tephrostratigraphy of the Faroe Islands region: The cryptotephra record
Previous studies of marine sequences from the Faroe Islands region have identified a series of coarse-grained tephra horizons deposited during Marine Isotope Stage (MIS) 5. Here we reassess the MIS 5 tephrostratigraphy of ...
Deformation bands in porous sandstones, their microstructure and petrophysical properties
(The University of Bergen, 2008-02-27)
Deformation bands are commonly thin tabular zones of crushed or reorganized grains that form in highly porous rocks and sediments. Unlike a fault, typically the slip is negligible in deformation bands. In this dissertation ...
Experimental investigations of Magnetization processes in Chinese loess
(The University of Bergen, 2011-11-25)
Coupled surface process and tectonic modelling of extension-inversion tectonics in the Pyrenees
(The University of Bergen, 2014-09-26)
Integration of ground-based hyperspectral and lidar scanning in virtual outcrop geology
(The University of Bergen, 2011-01-28)
The potential to visualize and analyse geological outcrops in a 3D environment has made terrestrial laser scanning (TLS) a standard method in geological field studies. Lidar models can be integrated with high resolution ...
Estimation of elastic moduli of mixed porous clay composites
We have developed a procedure for estimating the effective elastic properties of various mixtures of smectite and kaolinite over a range of confining pressures, based on the individual effective elastic properties of pure ...
The post-Caledonian history of the Røldal Shear Zone (SW Norway): an apatite fission track study
(The University of Bergen, 2015-04-27)
The post-Caledonian tectonic history and landscape evolution of southwestern Norway is not very well understood and therefore the subject of an ongoing debate. The lack of onshore post-Devonian sediments makes the ...
