Economic gas production from unconventional shale-gas reservoirs requires hydraulic
fracturing to reconnect and open existing fractures which are lower than the actual fracture …

Young's modulus, Poisson's ratio, and fracture excess compliances, which are related to
rock brittleness and natural fractures, can be used to evaluate the hydraulic fracturing and …

The special intrinsic characteristics of shale formations, such as multiscale pore systems and
complex mineral components, make the simulation of shale properties more difficult than …

Detection of fracture and fluid properties from subsurface azimuthal seismic data improves
our abilities to characterize the saturated porous reservoirs with aligned fractures. Motivated …

Horizontally transverse isotropy (HTI) induced by vertical or subvertical aligned fractures is
common for unconventional fractured porous shale oil or gas reservoirs. Compared with the …

At present, approaches based on the AVAaz (P-wave amplitude versus the incident angle
and azimuth) inversion are highly pivotal for estimating fracture parameters (namely fracture …

Fluid identification and fracture discrimination play an important role in the exploration and
development of an oil-bearing fractured reservoir. The most common fluid indicator in …

The ratio of normal-to-shear fracture compliances, approximate to the product of two ratios of
shear-to-compressional (S-to-P) wave velocity and normal-to-tangential fracture weakness …

Knowledge of in situ stress is of great significance for hydraulic fracture stimulating of
unconventional reservoirs. Quantitative estimation of in situ stress, especially in the far field …

Estimates of natural fractures or fracture-prone brittleness sweet spots are of great
importance for the seismic characterization of fracability and successful commercial …
