A sound understanding of the pore-fracture system across all scales provides an in-depth
look at the intricate gas transport mechanisms in shale reservoirs. We performed a …

Despite promising natural gas huff 'n'puff (HnP) field-pilot results, the dominant oil-recovery
mechanisms during this process are poorly understood. We conduct systematic natural-gas …

Diagenesis is a key process that affects carbonate reservoir formation and evolution. This
paper presents a detailed study of a carbonate shoal reservoir in the Ordovician Majiagou …

Solvent injection processes offer a promising alternative to steam-based techniques for
heavy oil recovery. Multiple mass transfer mechanisms, including interphase mass transfer …

One of the potential risks associated with subsurface storage of CO 2 is the seepage of CO 2
through existing faults and fractures. There have been a number of studies devoted to this …

Results of recent laboratory experiment studies suggest that huff-n-puff gas injection holds
great potential to increase oil recovery from shale oil cores. However, our current knowledge …

Hybrid solvent-and thermal-based methods offer an important potential for reducing the
environmental impact and enhancing recoveries in heavy oil production processes. Time …

Physical and chemical heterogeneities cause the porous media transport parameters to vary
with scale, and between these two types of heterogeneities geological heterogeneity is …

Shale barriers may act as flow barriers with adverse impacts on the steam chamber
development, as observed in numerous field-scale SAGD projects. Efficient …

Previous works in the literature demonstrated that dispersion increases with heterogeneities
and travel distance in heterogeneous reservoirs. However, it remains challenging to quantify …
