Fluid and effective fracture identification in reservoirs is a crucial part of reservoir prediction.
The frequency-dependent AVO inversion algorithms have proven to be effective for …

Seismic characterization of anisotropic in situ stress is of great importance in improving the
success of planning drilling and hydraulic fracturing treatment. Shales generally exhibit …

Geophysical and geologic data, eg, results obtained using rock cores, outcrops, and
borehole images, reveal the presence of multiple sets of fractures in rock. To analyze how …

Shale is a critical hydrocarbon reservoir generally considered a typical transverse isotropy
with a vertical axis of symmetry vertical transverse isotropic (VTI) media. Petrophysical …

Although subsurface media are usually assumed to be isotropic, anisotropy is ubiquitous in
crustal rocks and leads to the variation of seismic response with direction. Transversely …

Transverse isotropy with a horizontal axis of symmetry (HTI) media is generally considered
as parallel vertical cracks embedded in an isotropic matrix or vertically dip** shale …

Lithology discrimination plays an important role in characterizing deep-hydrocarbon
reservoirs, particularly for tight sandstones with special petrophysical properties. Stable …

Pre-stack seismic amplitude versus offset (AVO) inversion estimates reservoir properties by
relying on the variation of seismic data amplitude with offset, usually ignoring the role of …

Seismic wave exhibits the characteristics of anisotropy and attenuation while propagating
through the fluid-bearing fractured or layered reservoirs, such as fractured carbonate and …
