Pre-stack seismic inversion of the P-and S-wave velocities and bulk density is important in
seismic exploration for evaluating lithological units and fluid properties. Generally, this …

Shales represent strongly intrinsic vertical transverse isotropy (VTI) property or polar
anisotropy. The presence of vertically aligned fractures makes shale exhibit orthogonal …

Engineering dessert evaluation is an important role in the exploration and development of
unconventional oil and gas reservoirs such as shale. Brittleness and fracture parameter …

Quantitative inversion of fracture weakness plays an important role in fracture prediction.
Considering reservoirs with a set of vertical fractures as horizontal transversely isotropic …

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

Fluid discrimination is challenging for reservoir prediction, especially for tight sandstones
with special petrophysical properties. In this paper, we first review the effective medium …

Fracture detection and fluid discrimination play significant roles in the field of geothermics,
hydrogeology, and exploration geophysics. However, it is still a challenging task how to …

Existing methods of well-logging interpretation often contain errors due to the presence of
subsurface fracture networks within carbonate reservoirs. The differences of frequency …

Prestack seismic inversion can be regarded as an optimization problem, which minimizes
the error between the observed and synthetic data under the premise of certain geological …

In the absence of fracture, the strata with horizontal interbedding structure can be
approximately equivalent to transversely isotropic media with vertical axis of symmetry (VTI) …
