On the relative importance of global and squirt flow in cracked porous media
(Journal article, 2014)A unified theory of global and squirt flow in cracked porous media was developed several years ago on the basis of a combination of the dynamic T-matrix approach to rock physics. The theory has been successfully used to ... -
Rock physics interpolation Used for velocity modeling of chalks: Ontong Java plateau example
(Peer reviewed; Journal article, 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 incorporate ... -
Sedimentology and seuence stratigraphy of the late cretaceous lowe Ferron Sandstone: Application of 3-D geocellular modelling to the drunkards wash CBM-field in central Utha, USA
(Master thesis, 2010)Deposition of the Ferron Sandstone Member occurred during a widespread regression of the Western Interior Seaway during the Turonian. The Ferron is informally subdivided into two units. The Upper Ferron, ferronensis sequence ... -
Seismic characterization of reservoirs with multiple fracture sets using velocity and attenuation anisotropy data
(Journal article, 2011)Knowledge about the spatial distribution of the fracture density and the azimuthal fracture orientation can greatly help in optimizing production from fractured reservoirs. Frequency-dependent seismic velocity and attenuation ... -
The seismotectonics of western Skagerrak
(Peer reviewed; Journal article, 2011-04-20)The seismically active Skagerrak region in the border area between Denmark and Norway has traditionally been associated with uncertain earthquake locations due to the limited station coverage in the region. A new seismic ... -
Sr/Ca in Calcitic Tests of Benthic Foraminifera - A Potential Water-Depth Proxy?
(Peer reviewed; Journal article, 2009)Well-preserved low-Mg calcite tests of modern benthic foraminifera from a depth transect off SW Norway show decreasing Sr/Ca with increasing water depth (r = –0.84). The Mg/Ca ratios also decrease with increasing water ... -
Structural development of the Håsteinen Devonian Massif, its Caledonian substrate and the subjacent Nordfjord–Sogn Detachment Zone - a contribution to the understanding of Caledonian contraction and Devonian extension in West Norway
(Doctoral thesis, 2008-05-30)In western Norway, the contractional history of the Caledonian Orogeny ended with the Scandian continentcontinent collision between Baltica and Laurentia at around 420-400 Ma, resulting in formation of eclogites in the ... -
Temperature variability within the upper water masses of the western tropical Atlantic during rapid climate transitions
(Master thesis, 2010-01-20)Rapid reorganization of the ocean circulation in the Atlantic Ocean has been linked to widespread varations in climate on both millennial and glacial-interglacial timescales. The response of the tropical Atlantic upper ...
