Shear wave velocity (S-wave velocity or Vs) is one of the most critical issues for carbonate
reservoirs characterization, because of its complexity of rock compositions and pore …

Abstract The Majiagou Formation is an important gas-bearing stratigraphic unit in the Ordos
basin of west China. The highly complex lithology and heterogeneous pore systems make it …

Carbonate rocks are in general complex and commonly contain compound pore systems
that can significantly affect the variations of physical properties; their petrophysical …

The diversity and multiscale characteristics of pore types in carbonate rocks usually result in
extremely complex permeability–porosity relationships. Clarifying the main controlling …

Permeability prediction using linear regression of porosity always has poor performance
when the reservoir with complex pore structure and large variation of lithofacies. A new …

Carbonate rocks form under widely variable depositional settings and are susceptible to
complicated diagenetic processes which influence their petrophysical and elastic properties …

Pore types strongly influence fluid mobility of reservoirs. For a given porosity in different
rocks, the movable fluid saturation can differ> 30%. Previous studies commonly attribute this …

Permeability prediction of submarine shallow sediments is significantly important for finding
hydrate-bearing sands with commercial potential. Permeability could be more sensitive to …

The influence of unconventional oil on the petrophysical properties of carbonate rocks is of
primary interest in petroleum science. In this work, we first provided a thorough petrophysical …

The marine carbonate rock in the Changxing-Feixianguan Formation of Xuanhan-Daxian
area, northeastern Sichuan, the Sichuan Basin holds abundant natural gas resource, where …
