Abstract Development of shale gas exploration and recovery processes have become the
research focus of the scientific and industrial communities due to the acute depletion of …

Much attention have been recently paid to the upper Ordovician Wufeng shale (O 3 w) and
lower Silurian Longmaxi shale (S 1 l) in the Jiaoshiba area of Sichuan Basin, which is now …

Previous studies have determined many types of pores in shale, such as organic pores,
inorganic pores and microfractures. In this study, pores are classified as intergranular …

Nanoporosity of a shale gas reservoir provides essential information on the gas
accumulation space and controls the gas reserves. The characteristics of heterogeneous …

When fracturing a shale gas reservoir with supercritical CO 2, the interaction between CO 2
and shale will change the pore structure, thus affecting the mechanical properties of shale …

Pore structure is of great importance in the occurrence of shale gas. In this study, pores in
shale samples from the Lower Silurian Longmaxi and Lower Cambrian Niutitang shales in …

Small-angle neutron scattering (SANS), helium pycnometry, and low-pressure gas sorption
isotherm experiments were used to investigate the pore characteristics of Longmaxi shale …

Pore structure can greatly impact the gas storage and flow mechanisms in shale reservoirs.
Pore characteristics, including the pore (body/throat) size distribution (PSD), porosity …

By combining the micro-CT, SEM, FIB-SEM and FIB-HIM, a multiscale characterization
method was explored to study the pores in Wufeng-Longmaxi shale, Sichuan Basin, China …

The pore size classification (micropore< 2 nm, mesopore 2–50 nm and macropore> 50 nm)
of IUPAC (1972) has been commonly used in chemical products and shale gas reservoirs; …
