Evolution of small-scale flow barriers in German Rotliegend siliciclastics
Autor: Alexandra Amann-Hildenbrand, Georg Nover, Benjamin Busch, Christoph Hilgers, Rebecca Winkler, Keyvan Osivandi
Publikováno v: Special publications / the Geological Society, London, 435 (141-160)
Many siliciclastic reservoirs contain millimetre-scale diagenetic and structural phenomena affecting fluid flow. We identified three major types of small-scale flow barriers in a clastic Rotliegend hydrocarbon reservoir: cataclastic deformation bands

Changes of petrophysical properties of sandstones due to interaction with supercritical carbon dioxide – a laboratory study
Autor: S. Heikamp, Jutta von der Gönna, Jens Köster, Georg Nover
Publikováno v: European Journal of Mineralogy. 25:317-329
Changes of petrophysical, petrological, mineralogical, mechanical and chemical parameters were studied on sandstones from the Hessian Depression and sandstones from Neidenbach (Eifel) before and after alteration with CO2. The experiments were perform

Carbonate diagenesis and feldspar alteration in fracture-related bleaching zones (Buntsandstein, central Germany): possible link to CO2-influenced fluid–mineral reactions
Autor: Jens E Wendler, Georg Nover, Dieter Pudlo, Norbert Zisser, Jens Götze, Jens Köster, Norbert Kasch, Reinhard Gaupp, Jonas Kley
Publikováno v: International Journal of Earth Sciences. 101:159-176
Fracture-related bleaching of Lower Triassic Buntsandstein red beds of central Germany was related to significant carbonate diagenesis and feldspar alteration caused by CO2-rich fluids. Using cathodoluminescence microscopy and spectroscopy combined w

Relationship between low-frequency electrical properties and hydraulic permeability of low-permeability sandstones
Autor: Andreas Kemna, Georg Nover, Norbert Zisser
Publikováno v: GEOPHYSICS. 75:E131-E141
The relationship between low-frequency electrical properties and hydraulic permeability of rocks has been the focus of geophysical investigations for a long time because it offers a possibility for an in situ and noninvasive permeability estimation o

Anisotropy of permeability and complex resistivity of tight sandstones subjected to hydrostatic pressure
Autor: Norbert Zisser, Georg Nover
Publikováno v: Journal of Applied Geophysics. 68:356-370
The dependence of permeability and complex electrical resistivity on direction was measured for low-permeable sandstone samples from a tight gas reservoir. Both properties were measured in three directions at hydrostatic pressures up to 100 MPa. The

Electrical properties of a graphite-rich quartzite from a former lower continental crust exposed in the Serre San Bruno, Calabria (southern Italy)
Autor: Hartmut Jödicke, Rudolf Markfort, Georg Nover, Jörn H. Kruhl
Publikováno v: Physics of the Earth and Planetary Interiors. 165:56-67
In this study electrical properties of a graphite-rich quartzite from the former lower crust exposed in the Serre San Bruno, Calabria (southern Italy) have been analysed by means of complex electrical conductivity measurements in the frequency range
