Shales are considered to be both source and cap rocks, and play an important role in
various geotechnical applications including oil and gas exploration and production. A deep …

Anisotropy of elastic properties in clay‐rich sedimentary rocks has been of long‐standing
interest. These rocks are cap rocks of oil and gas reservoirs, as well as seals for carbon …

Tilted transverse isotropy (TTI) provides a useful model for the elastic response of a medium
containing aligned fractures with a symmetry axis oriented obliquely in the vertical and …

We obtained the complete set of dynamic elastic stiffnesses for a suite of “shales”
representative of unconventional reservoirs from simultaneously measured P-and S-wave …

Optimizing the productivity of nonconventional, low‐permeability “shale” reservoirs requires
detailed knowledge of the mechanical properties of such materials. These rocks' elastic …

Led by new developments of horizontal drilling and hydraulic fracturing techniques, organic
rich shales have been contributing significantly to a gas production in the US. In drilling …

Plenty of mechanical experiments have been done to investigate the deformation and failure
characteristics of shale; however, the anisotropic failure mechanism has not been well …

Quantitative rock physical approaches are becoming increasingly important for both
geophysical exploration and geological interpretation. One limiting factor is that …

ABSTRACT A novel inversion method for the laboratory determination of Thomsen's δ
anisotropy parameter on cylindrical rock specimens from ultrasonic data has been recently …

The inversion of reservoir elastic parameters and fracture parameters is of great significance
to oil and gas production. In shale reservoirs with inclined fractures, using the reflection …
