Subsurface porous rocks hold significant hydrogen (H2) storage potential to support an H2-based energy future. Understanding H2 flow and trapping in subsurface is crucial reliably evaluate their efficiency. In this work, we perform cyclic visualization experiments on a layered rock sample with varying pore throat sizes. During drainage, follows path consisting of large pores throats, through low permeability layer, substantially reducing capacity. Moreover, due the heterogeneity depending experimental strategy, imbibition unexpectedly results higher saturation compared drainage. These emphasize that small-scale heterogeneity, which often unaccounted for reservoir-scale models, plays vital role displacement media, implications efficient strategies.

In this research, a novel natural-based polymer, the Aloe Vera biopolymer, is used to improve mobility of injected water. Unlike most synthetic chemical polymers for chemical-enhanced oil recovery, biopolymer environmentally friendly, thermally stable in reservoir conditions, and compatible with rock fluids. addition, efficiency was investigated presence new nanocomposite composed KCl-SiO2-xanthan. This chemically enhanced recovery method applied on sandstone Southwest Iran crude an API gravity 22°. The biopolymer's physicochemical characteristics were initially examined using different analytical instruments. results showed that under conditions. no precipitation occurred formation brine at salinity 80,000 ppm. experimental adding ethanol 10% volume percentage reduced interfacial tension 15.3 mN/m contact angle 108°, which 52.33 55.56% these values, respectively. On other hand, lowered values 4 48°, corresponding reducing by 87.53 71.42%, rheology solutions prepared ethanol, Newtonian fitted Herschel-Bulkley model. Finally, core flooding application solution effective increasing factor, where maximum factor 73.35% achieved, could be attributed IFT reduction, wettability alteration, improvement mechanisms.
