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 ... -
Mechanical and physical behavior of high-porosity chalks exposed to chemical perturbation
Megawati, Megawati; Madland, Merete Vadla; Hiort, Aksel (Journal article; Peer reviewed, 2015-09)Extensive study on the effect of dissolution–precipitation on mechanical behavior of various high-porosity outcrop chalks (Liége, Aalborg, Kansas, Stevns Klint, and Mons) flooded with simplified aqueous chemistry at 130 ... -
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 ...
