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 …

The development of hydraulic fracturing and horizontal drilling techniques has promoted the
exploitation of shale gas resources. However, using water has several potential drawbacks …

Shale reservoirs are extensively exploited using hydraulic fracturing, which forms multiple
cracks that connect with the existing natural fractures to create a continuous path for the gas …

Shale gas, although unconventional, is a prospective clean energy source. Shale gas
production is a complex multi-scale process with its spatial size ranging from the nanoscale …

Hydrocarbons in subsurface nanoporous media, such as shale, are promising energy
resources to compensate for the shortage of conventional reservoirs. Pore-network …

Multiple transport mechanisms coexist in nanopores of shale gas reservoirs with complex
pore size distribution and different gas-storage processes, including continuum flow, slip …

Surface diffusion plays a key role in gas mass transfer due to the majority of adsorbed gas
with abundant nanopores of organic matter in shale gas reservoirs. Surface diffusion …

A model for gas transfer in nanopores is the basis for accurate numerical simulation, which
has important implications for economic development of shale-gas reservoirs (SGRs). The …

CO 2 injection is a promising technique that not only enhances shale gas recovery but also
achieves geological storage of CO 2. This paper reviewed the performance of CO 2 injection …
