The depleted gas reservoirs can serve not only as sites for CO$_2$ sequestration but also as potential spaces for hydrogen storage. However, this process remains insufficiently investigated and thus cannot offer reliable technical support for the injection operations. In this study, a mathematical model for simulating hydrogen storage in depleted gas reservoirs was developed and numerically solved. Meanwhile, the applicability was then verified through comparison with results from previous studies. Based on this model, a detailed analysis was performed to investigate the evolution of key parameters under specific injection conditions. Finally, the effects of various factors on parameters suc...

The geothermal resources present within the reservoir post-oil production in the oil field have hitherto been overlooked and underdeveloped, constituting a novel energy supplement for the maintenance of energy security. The present study constructed a geothermal transmission and exploitation model for oil reservoirs based on the geological environment and the characteristics of geothermal transmission media. This model can be used to analyse the impact of different factors on the efficiency of reservoir geothermal resources. Concurrently, a molecular dynamics model was constructed to reveal the geothermal transmission mechanism at a microscopic perspective, which will facilitate the optimisa... More >

Reservoir Science (RS) journal represents a significant milestone in the pursuit of energy extraction, energy storage, and the multifarious effects of climate change, which are influenced by the dual factors of global climate variability and energy scarcity. Concurrently, Reservoir Science is dedicated to the dissemination of innovative modules and research domains pertaining to energy extraction, energy storage, reservoir environment and greenhouse gas storage. Furthermore, the field of Reservoir Science encompasses the exploitation of geothermal energy, hydrocarbons (petroleum, hydrates) and hydrogen energy within reservoirs. The research scope of Reservoir Science encompasses not only the... More >
