An Analytical TOOLBOX for the Characterization of Chalks and Other Fine-Grained Rock Types within Enhanced Oil Recovery Research and Its Application—A Guideline
Zimmermann, Udo; Minde, Mona Wetrhus; Madland, Merete Vadla; Bredal, Tine Vigdel (Peer reviewed; Journal article, 2022-06)Analyses of fine-grained rocks like shales, cherts, and specifically chalk are challenging with regards to spatial resolution. We propose a “toolbox” to understand mineralogical alteration in chalk, especially those induced ... -
Effect of Initial Wettability on Rock Mechanics and Oil Recovery: Comparative Study on Outcrop Chalks
Sachdeva, Jaspreet Singh; Nermoen, Anders; Korsnes, Reidar Inge; Madland, Merete Vadla (Peer reviewed; Journal article, 2020)Brines containing surface-active divalent ions such as Ca2+, Mg2+ and SO42− impact the stiffness, strength and time-dependent deformation of water wet Mons outcrop chalk. This study documents how stiffness and strength of ... -
High-Resolution Topographic and Chemical Surface Imaging of Chalk for Oil Recovery Improvement Applications
Bredal, Tine Vigdel; Zimmermann, Udo; Madland, Merete Vadla; Minde, Mona Wetrhus; Ost, Alexander D.; Wirtz, Tom; Audinot, Jean-Nicolas; Korsnes, Reidar Inge (Peer reviewed; Journal article, 2022-03)Chalk is a very fine-grained carbonate and can accommodate high porosity which is a key characteristic for high-quality hydrocarbon reservoirs. A standard procedure within Improved Oil Recovery (IOR) is seawater-injection ... -
A laboratory scale approach to wettability restoration in chalk core samples
Sachdeva, Jaspreet Singh; Sripal, Edison A.; Nermoen, Anders; Korsnes, Reidar Inge; Madland, Merete Vadla; James, Lesley A. (Peer reviewed; Journal article, 2019)Wettability in chalk has been studied comprehensively to understand fluid flow mechanisms impacting coreflooding experiments. Wettability becomes paramount in understanding the parameters influencing chalk-fluid interactions. ... -
Mineral replacement in long-term flooded porous carbonate rocks
Minde, Mona Wetrhus; Zimmermann, Udo; Madland, Merete Vadla; Korsnes, Reidar Inge; Schultz, Bernhard; Gilbricht, Sabine (Peer reviewed; Journal article, 2019-09)This study reports mineralogical and physical property changes linked to geo-chemical alterations processes during three ultra-long-term tri-axial tests on outcrop-chalk from Liège (Belgium). The test core plugs were flooded ... -
Mineralogy and geochemistry of reservoir and non-reservoir chalk from the Norwegian continental shelf
Kallesten, Emanuela Iedidia; Zimmermann, Udo; Madland, Merete Vadla; Bertolino, Silvana R.A.; Omdal, Edvard; Andersen, Pål Østebø (Peer reviewed; Journal article, 2021-05)A first and detailed study of the geochemistry and mineralogy characterizing the North Sea reservoir and non-reservoir chalk is provided in this work. The study is based on 185 cores from exploration and development wells ... -
Water Weakening of Artificially Fractured Chalk, Fracture Modification and Mineral Precipitation during Water Injection—An Experimental Study
Bredal, Tine Vigdel; Korsnes, Reidar Inge; Zimmermann, Udo; Minde, Mona Wetrhus; Madland, Merete Vadla (Peer reviewed; Journal article, 2022-05)This experiment was designed to study the water-weakening effect of artificially fractured chalk caused by the injection of different compositions of brines under reservoir conditions replicating giant hydrocarbon reservoirs ...
