Experimental study and machine learning modeling of organic-nano-aged Saudi Arabian Basalt: An implication to gas geo-storage

Abstract Understanding the wettability of carbon dioxide (CO 2 ) and the interfacial properties between reservoir rocks and fluids is crucial for the effective geological carbon sequestration (GCS). The most accurate way to measure these properties is the laboratory experiments under simulated reservoir conditions. However, experimental measurement of CO 2 wettability in storage/caprock, influenced by thermo-physical conditions, poses significant challenges due to the reactivity and embrittlemen
