The further development of unconventional resources is anticipated to increase the intensity
of hydraulic fracturing operations. Injecting water-based fracturing fluids into shale …

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

Supercritical carbon dioxide (sc-CO 2) is an alternative to water for stimulation of low
permeability systems such as shale gas and geothermal resources. Previously core-scale …

In situ shale or kerogen oil production is a promising approach to developing vast oil shale
resources and increasing world energy demand. In this study, cyclic subcritical water …

Shale reservoir heterogeneity is strong, which seriously affects shale gas reservoir
evaluation and reserves estimation. The Longmaxi Formation shale of the Luzhou block in …

In cold regions, combined cyclic freeze-thaw (FT) and loading-unloading can cause rock
slope instability and sliding. The macro-failure of rock masses originates from the expansion …

The present study attempted to analyze the features of atlanto‐occipital radiograph in
patients with cervical spondylotic radiculopathy or vertebral artery type. In order to reduce …

Rate-dependent behavior associated with deformation and fracturing of materials poses
significant challenges for modeling. In addition to the complications of the viscoelastic …
