Evaluation of the compositional changes during flooding of reactive fluids using scanning electron microscopy, nano-secondary ion mass spectrometry, x-ray diffraction, and whole-rock geochemistry
Zimmermann, Udo; Madland, Merete Vadla; Nermoen, Anders; Hildebrand-Habel, Tania; Bertolino, Silvana A.R.; Hiort, Aksel; Korsnes, Reidar; Audinot, Jean-Nicolas; Grysan, Patrick (Journal article; Peer reviewed, 2015-05)Outcrop chalk of late Campanian age (Gulpen Formation) from Liège (Belgium) was flooded with MgCl2 in a triaxial cell for 516 days under reservoir conditions to understand how the non-equilibrium nature of the fluids altered ... -
How stress and temperature conditions affect rock-fluid chemistry and mechanical deformation
Nermoen, Anders; Korsnes, Reidar I.; Aursjø, Olav; Madland, Merete V.; Kjørslevik, Trygve A.C.; Østensen, Geir (Journal article; Peer reviewed, 2016-03)We report the results from a series of chalk flow-through-compaction experiments performed at three effective stresses (0.5, 3.5, and 12.3MPa) and two temperatures (92 and 130◦C). The results show that both stress and ... -
Incorporating electrostatic effects into the effective stress relation — Insights from chalk experiments
Nermoen, Anders; Korsnes, Reidar Inge; Storm, Eirik V.; Stødle, Trond; Madland, Merete Vadla; Fabricius, Ida Lykke (Journal article; Peer reviewed, 2018-01)Which forces are responsible for holding highly porous chalks together? We use the effective stress to quantify the electrostatic effects around particle contacts originating from the adsorption of ions onto charged mineral ... -
Porosity and permeability development in compacting chalks during flooding of nonequilibrium brines: Insights from long-term experiment
Nermoen, Anders; Korsnes, Reidar I.; Madland, Merete V.; Hiort, Aksel (Journal article; Peer reviewed, 2015-05)We report the complete chemical alteration of a Liège outcrop chalk core resulting from a 1072 flow-through experiment performed during mechanical compaction at 130°C. Chemical rock-fluid interactions alter the volumetric ... -
Streaming potential - qualification of method and investigating the impact of brine in sandstone core plugs
Horvei, Bendik (Master thesis, 2017-06-15)Streaming potential is an electrokinetic phenomenon caused by relative motion of ions close to a charged surface when a fluid moves past it. By measuring the streaming potential, information related to the surface ...
