... Abstract Hydrogen storage plays a critical role in advancing hydrogen as a sustainable energy source. The materials used in hydrogen storage tanks must adhere to stringent standards, especially in hot climates where elevated temperatures can accelerate material degradation and affect storage...

..., the fracture properties in fracturing flooding wells vary with time during the shut-in testing period since they are not strengthened by proppants. Linear-flow analysis, fracture-storage coefficient analysis, and fracturing flooding interference analysis methods are comprehensively discussed and compared...

... Abstract Brine-gas interfacial tension ( γ ) is an important parameter to determine fluid dynamics, trapping and distributions at pore-scale, thus influencing gas (H 2 , CH 4 and CO 2 ) geo-storage (GGS) capacity and security at reservoir-scale. However, γ is a complex function of pressure...

...Conclusion This study presented a pore network simulation for the prediction of the relative permeability for both hydrogen-brine and cushion- gas-brine for underground hydrogen storage. The pore network model, which was generated, was validated using petrophysical characteristics...

... hydrogen storage reservoirs. Simulation results demonstrate significant H 2 S generation during withdrawal cycles, posing challenges for hydrogen recovery and utilization. Factors influencing H 2 S production include reaction kinetics, sulfate concentration, reservoir pressure, temperature, and formation...

.... Dope-free tubulars replace the storage and running pipe dope historically used in casing and tubing by a dry coating applied on pipe threads in an industrial controlled environment. The elimination of dope greatly simplifies the supply chain process involved in preparing casing and tubing for onshore...
