Abstract The Cenomanian/Turonian period is characterized by the deposition of organic-rich
and fine-grained sediments that form important source rocks and unconventional reservoir …

High‐precision permeability prediction is of great significance to tight sandstone reservoirs.
However, while considerable progress has recently been made in the machine learning …

Petrophysical reservoir quality assessment is achieved through several methods based on
the pore volume, connectivity, and conductivity. Reservoir quality index (RQI), and reservoir …

Flow units (FUs) have been widely used for rock typing in many reservoirs, especially where
there is no direct correlation between petrophysical properties and geological …

Drilled cores, thin section petrography, X-ray diffraction (XRD), scanning electron
microscopy (SEM), routine core analysis (RCA), and mercury injection capillary pressure …

The effects of overburden pressure on porosity and permeability are often neglected in
formation evaluation, while it has important influences on reservoir storage and flow …

The Chang 6 tight sandstone reservoir of the Upper Triassic, developed in a large lacustrine
shallow-water delta depositional environment, is the most important target for oil exploration …

The classification of low permeability-tight reservoirs is the premise of development. The
deep reservoir of Shahejie 3 member contains rich low permeability-tight reserves, but the …

This study delineates sandstone reservoir flow zones in the north-western Bredasdorp
Basin, offshore South Africa, using conventional core porosity and permeability data. The …

By determining the hydraulic flow units (HFUs) in the reservoir rock and examining the
distribution of porosity and permeability variables, it is possible to identify areas with suitable …
