The success of geological H2 storage relies significantly on rock–H2–brine interactions and wettability. Experimentally assessing the H2 wettability of storage/caprocks as a function of thermos-physical conditions is arduous because of high H2 reactivity and embrittlement damages. Data-driven machine learning (ML) modeling predictions of rock–H2–brine wettability are less strenuous and more precise. They can be conducted at geo-storage conditions that are impossible or hazardous to attain in the laboratory. Thus, ML models were utilized in this research to accurately model the wettability behavior of a ternary system consisting of H2, rock minerals (quartz and mica), and brine at different operating geological …

Subsurface geologic formations such as depleted hydrocarbon reservoirs, deep saline aquifers and shale formations have been considered promising targets for carbon dioxide and hydrogen storage. A solid understanding of the interfacial properties of multiphase systems, including binary (pure gas-water) and ternary (gas mixtures and water), is vital to assess for reliability and storage capacity of the geological formations. However, most previous experimental and simulation studies for interfacial properties have mainly focused on binary systems at low-medium pressure. Only a few experimental and simulation studies investigated the interfacial tension at high pressure (above 20 MPa) for the CO2-CH4 …

In hydrogen geological storage, cushion gas has vital role to retain adequate reservoir pressure to keep the hydrogen withdrawal stable. Presence of the cushion gas in the storage reservoir can affect the flow characteristics of hydrogen during injection and production cycles. One of the most crucial parameters that control the fluids flow in porous media is interfacial tension (IFT) between fluids. However, the literature data lacks in terms of IFT between cushion gas mixed with hydrogen and brine at geo-storage conditions. In this study, the pendant drop method was used to measure the IFT of (brine + H2 + …
