Abstract Hydrogen Storage in subsurface formations has become increasingly essential as the global demand for clean and renewable energy rises. Unlike CO2 methane, hydrogen due to its smaller molecular size is more susceptible slippage effects it flows through porous formations. Although current studies gases such methane have established behavior, extend of these impacts on rocks not completely known. To increase storage, assure long-term stability, prevent losses, important that this knowledge gap closed. Using steady–state flow studies, gas-brine relative permeability core samples from San Juan Formation investigated with a special focus Klinkenberg at various confining pressures temperatures. For conditions, new linear correlations between gas–measured were generated. The gas was then calibrated using correlations, revealing overestimating might result ignoring effects. experiments performed under ambient elevated conditions simulating environments. results provide thorough insights into how reduce both water permeabilities, while temperature plays distinct role by decreasing increasing permeability. derived further utilized examine response gas-water changes gas-measured investigate impact permeability, temperature, pressure. Results reveal existence mobile greatly reduces compared irreducible water. Raising effective permeabilities phases; however, because phase sensitive pressure, increases falls. major measurements underscored fact higher temperatures resulted decline an These findings significant implications application underground particularly tight In addition providing crucial information estimating reservoirs, experimental offer framework evaluating storage efficiency critical data modeling reservoirs. create options avoid slippage-induced overestimates, developed can be used forecast behavior hydrogen. This research paves way advancing technologies, making viable solutions future needs.
