Fracture-generated permeability and groundwater yield in Norway
Gjesdal, Otilie; Gudmundsson, Agust; Fjeldskaar, Ingrid (NGU Bulletin (439), Journal article, 2002)The transport of groundwater in bedrock is largely determined by interconnected fractures and their apertures. The conditions by which fractures become interconnected are thus of primary importance in understanding ... -
Permeability development during hydrofracture propagation in layered reservoirs.
Brenner, Sonja L.; Gudmundsson, Agust (NGU Bulletin (439), Journal article, 2002)Hydrofractures are generated by internal fluid overpressure and together with shear fractures, contribute significantly to the permeability of water, oil or magma reservoirs. We use boundary-element models to explore the ... -
The importance of hydraulic gradient, lineament trend, proximity to lineaments and surface drainage pattern for yield of groundwater wells on Askøy, West Norway.
Lie, Hallstein; Gudmundsson, Agust (NGU Bulletin (439), Journal article, 2002)Groundwater and lineament studies were made on Askøy, an island northwest of Bergen. In addition to field measurements of lineaments and associated fractures, a total of 2695 photolineaments and 409 topolineament were ...
