Deltaic clinothems − Digital data capture, geometries, and reservoir implications
(The University of Bergen, 2008-12-15)
Subsurface reservoir models are typically limited by a lack of spatially accurate geometric data on bedform architecture and geometry, which are key controls on fluid flow. Outcrop analogues have long been utilized as a ...
Bruddsystem og spenningsfelt tilknyttet tunneltraséen Ringveg Vest i Bergen
(The University of Bergen, 2003)
Denne hovedfagsoppgaven er en del av forundersøkelsene som er utført i sammenheng med tunnelprosjektet Ringveg Vest i Bergen kommune, Hordaland, som har driftstart i 2005. Ringveg Vest er planlagt å ligge cirka 4 kilometer ...
Rock physics interpolation Used for velocity modeling of chalks: Ontong Java plateau example
(Bentham Open, 2010)
Chalks are pelagic carbonate sediments that are deposited in deep-water environments. Their elastic behaviour is controlled by a combination of depositional conditions and subsequent diagenesis. In this paper, we ...
Experimental investigation of deformation mechanisms during shear-enhanced compaction in poorly lithified sandstone and sand
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 ...
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 ...
Northern hemisphere glaciation during the globally warm early late Pliocene
The early Late Pliocene (3.6 to ,3.0 million years ago) is the last extended interval in Earth’s history when atmospheric CO2 concentrations were comparable to today’s and global climate was warmer. Yet a severe global ...
Seismic Attributes for Carbonates
(The University of Bergen, 2009-06-02)
Seismic attributes can reveal important information about rock properties, and rock physics modeling provide a link between geological and seismic parameters. Carbonate rocks can have wide variations in properties due to ...
From mountains to basins: geochronological case studies from southwestern Norway, Western Australia and East Antarctica
(The University of Bergen, 2012-03-02)
Paleoclimate changes inferred from stable isotopes and magnetic properties of organic-rich lake sediments in Arctic Norway
Stable isotope measures in organic matter are frequently used as indicators of past climate change. Although such analyses can provide valuable information, there is considerable uncertainty associated with studies of ...
Ice-sheet dynamics and glacial development of the Norwegian continental margin during the last 3 million years
(The University of Bergen, 2007-06-29)
This thesis is mainly about the dynamics of the palaeo-ice sheets that covered Scandinavia, Barents Sea and Svalbard during the last glaciation. Morphological interpretation of regional and detailed bathymetric data sets ...
