Shear logs, also known as shear velocity logs, are used for various types of seismic
analysis, such as determining the relationship between amplitude variation with offset (AVO) …

Elastic modulus is a crucial mechanical parameter that measures the stiffness property of
rock materials. In underground rock engineering, such as deep energy development and …

The wave reflection and transmission (R/T) coefficients in fluid-saturated porous media with
the effect of effective pressure are rarely studied, despite the ubiquitous presence of in situ …

Sedimentary strata typically exhibit the characteristics of transverse isotropy (VTI) with a
vertical axis of symmetry. However, fractures in sedimentary strata tend to produce …

The research objectives are to assess the possibility of using drill cutting analysis to obtain
information about the mineralogical and geochemical properties of the reservoir rocks. Drill …

Fractures are widely distributed in upper crustal rocks and significantly affect rock elasticity.
Experiments and field studies indicate that pressure influences the rock's elastic properties …

The wave-induced fluid flow (WIFF) occurring in the ubiquitous layered porous media (eg,
shales) usually causes the appreciable seismic energy dissipation, which further leads to …

The similarities and differences in inherent mechanism and characteristic frequency
between the one-dimensional (1D) poroelastic model and the layered White model were …

Estimating gas enrichments is a key objective in exploring sweet spots within tight
sandstone gas reservoirs. However, the low sensitivity of elastic parameters to gas …

Predicting microcracks is crucial for identifying tight sandstones with high permeability,
which is essential for economic gas production. However, effective methods for directly …
