Review of Experimental Sorption Studies of CO2 and CH4 in Shales
Klewiah, Isaac; Berawala, Dhruvit Satishchandra; Walker, Hans Christian Alexander; Andersen, Pål Østebø; Nadeau, Paul Henry (Journal article; Peer reviewed, 2019-10)In recent years CO2 injection in shale has been investigated with aim to enhance shale gas recovery (ESGR) and permanently sequester CO2. This paper reviews the state of research on CH4 and CO2 sorption in shale. We present ... -
Simulation and Prediction of Countercurrent Spontaneous Imbibition at Early and Late Time Using Physics-Informed Neural Networks
Abbasi, Jassem; Andersen, Pål Østebø (Peer reviewed; Journal article, 2023-09)The application of physics-informed neural networks (PINNs) is investigated for the first time in solving the one-dimensional countercurrent spontaneous imbibition (COUCSI) problem at both early and late time (i.e., before ... -
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 ... -

Water flooding of Eldfisk reservoir cores
Cherif, Yosra (Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)Enhanced Oil Recovery (EOR) and the effect of the aqueous chemistry on the mechanical strength of chalk have been extensively studied over the years. This is simply because the stability of the reservoir system is affected ...
