... In this paper, the SS wave splitting correction method for multi fracture layers (Yue et al, 2020) was further illustrated for the case of depth-variant fracture orientation and was simplified to an easier-to-implement version for the case of fracture orientation doesn’t vary with depth but time...

Then according to the fracture orientations obtained from each CMP...

... fracture orientation and 2-term Fourier series is proposed to iteratively estimate fracture orientation without 90° uncertainty and the anisotropic gradient of the AEI indicating fracture density. Finally, the field data are carried out to confirm the effectivity and robustness of the above method...

... fracture orientation: AVOA of SV-SV and SH-SH wave could indicate fracture orientation at near offset (offset-depth ratio or ODR=0.4). Compared with P-SV and SH-SH wave, SV-SV wave is more sensitive to the change of anisotropy parameter caused by fluid substitution. Shear wave splitting analysis shows...

... fracture orientation, fracture spacing, and fracture compliance as a function of spatial location. The fracture orientation parameter is the most readily determined parameter. The beam interference amplitude depends on both fracture spacing and compliance in a local average sense for random fractures...

This study focus on a pragmatic and robust method in the estimation of fracture orientation assuming a single set of aligned fractures. Young's modulus in the direction of fracture orientation is known to be bigger than...

These angle gathers were then stacked for each azimuth and analyzed for azimuthal anisotropy to estimate the fracture orientation and relative fracture density. Finally, the results of the seismic azimuthal analysis were corroborated...
