Efficient Optimization and Robust Value Quantification of Enhanced Oil Recovery Strategies
Oguntola, Micheal Babatunde (PhD thesis UiS;, Doctoral thesis, 2022-06)With an increasing demand for hydrocarbon reservoir produces such as oil, etc., and difficulties in finding green oil fields, the use of Enhanced Oil Recovery (EOR) methods such as polymer, Smart water, and solvent flooding ... -
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 ... -
MICP-Based Rock Typing of Complex, Multi-Modal Formations in Edvard Grieg Field
Hedda, Svendsen (Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Rock/pore typing is a process of classifying reservoir rocks into units with similar petrophysical properties. When properly classified, each unit possesses a unique porosity-permeability relationship. This leads to improved ... -
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 ...
