Unconventional oil reservoirs have become an increasingly essential resource for energy in
recent years. Despite the massive oil reserves in these reservoirs, as well as the current …

We present a predictive species-based model for binary gas mixture transport through
nanoporous media using modified Maxwell–Stefan formulations for the free and sorbed …

Cyclic solvent injection, known as solvent huff-n-puff, is one of the promising techniques for
enhancing oil recovery from shale reservoirs. This study investigates the huff-n-puff …

Carbon geo-sequestration is a promising method for mitigating global warming and climate
change. Depleted shale gas reservoirs with high adsorption capacities, excellent sealing …

Due to the extensive presence of nanopores, the slippage effect is frequently invoked in
shale to enhance gas transport, therefore, causing the more than expected gas production …

Multicomponent gas transport in nanoporous adsorption media, such as organic-rich shales,
is influenced by various mechanisms of mass transport and storage, posing challenges to …

The occurrence of capillary condensation is often ignored in many naturally occurring
nanoporous media, such as shale rock, simply because their isotherms do not adhere to the …

Shale gas reservoirs are organic rich formations with often ultra-low permeability. Gas is
stored in free and adsorbed form. Conventional Darcy flow cannot fully describe the gas …

This work studies 1D steady-state flow of gas from compressible shale matrix subject to
water blocking toward a neighboring fracture. Water blocking is a capillary end effect …
