The selection of an optimized gas adsorption model is a quantitatively challenging task
when characterizing shale gas reservoirs because every model has its own assumptions …

Gas transport characteristics in shale matrix can be represented by permeability. However,
shale gas flow is influenced by multiple mechanisms, and existing matrix permeability …

This chapter describes the traditional approaches and recently developed models for in-
place natural gas resource and reserve estimation calculations suitable for reservoir rocks …

Hydraulic fractures connecting to the adjacent induced fracture network significantly promote
the productivity of unconventional gas reservoirs. Precise characterization of the fracture …

Gas production from shale gas reservoirs is determined by original gas-in-place and gas
transport mechanism in shale. Gas storage in shale consists of three different states: first …

Capillary spontaneous imbibition is vital to the successful development of shale reservoirs.
The two-phase flow macro-properties of shale are significantly difficult to be measured in the …

A large amount of liquid is pumped into the shale gas reservoir during hydraulic fracturing,
and the fluid flowback ratio is usually low. However, field experience showed that the liquids …

The gas sorption capacity, effective porosity, and effective permeability are important to
shale gas reservoir characterization, gas-in-place estimation, and production behavior …

Gas huff-n-puff injection, which avoids the viscous fingering phenomenon or gas channeling
between connected wells, is a potential method to efficiently enhance oil recovery (EOR) in …

Gas sorption and non-Darcy flow are two important issues for shale gas reservoirs. The
sorption consists of dissolution and adsorption. Dissolved gas and adsorbed gas are …
