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 ... -
Permeability evolution of shear failing chalk cores under thermochemical influence
Kallesten, Emanuela Iedidia; Andersen, Pål Østebø; Madland, Merete Vadla; Korsnes, Reidar Inge; Omdal, Edvard; Zimmermann, Udo (Peer reviewed; Journal article, 2020-04)Development of petroleum reservoirs, including primary depletion of the pore pressure and repressurization during water injection naturally, leads to changes in effective stresses of the formations. These changes impose ... -
Validation study of water weakening research from outcrop chalks performed on Eldfisk reservoir cores
Kallesten, Emanuela Iedidia; Cherif, Yosra; Madland, Merete Vadla; Korsnes, Reidar Inge; Omdal, Edvard; Andersen, Pål Østebø; Zimmermann, Udo (Peer reviewed; Journal article, 2020-11)Seawater injection for Enhanced Oil Recovery (EOR) purposes can increase the hydrocarbon recovery factor in carbonate reservoirs but are also responsible for weakening their mechanical strength. This study investigates the ... -
