Recovery Factor of Pure Helium Injection in Depleted Gas Reservoirs and Its Influencing Factors
Energy Science &Engineering, EarlyView.This study employs compositional numerical simulation to systematically investigate the effects of injection rate, production rate, storage duration, and injection‐production scheme on pure helium recovery in depleted gas reservoirs. Low injection rates reduce viscous fingering while high production rates maximize near‐wellbore helium extraction ...

Energy Science &Engineering, EarlyView.The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.

Mesoscopic seepage velocity characteristics during heap leaching based on magnetic resonance imaging
工程科学学报, 2015 Column leaching seepage processes were detected in a non-contact and non-destructive way by magnetic resonance imaging. Column leaching images were obtained when the flow was stationary and running.

Numerical Investigation of Methane Transport Within and Around Evolving Cracks
Energy Science &Engineering, EarlyView.A validated model shows that natural gas leakage induces soil deformation and forms three key cracks. When diffusion is low, methane moves mainly along the primary crack, demonstrating how natural fractures reshape pathways and significantly enhance methane migration.
