Linearized AVO and poroelasticity
TL;DR: In this paper, the authors used the theory of poroelasticity to derive a generalized amplitude variation with offset (AVO) approximation that provides the estimation of fluid, rigidity, and density parameters.

Estimation of stress and geomechanical properties using 3D seismic data
TL;DR: In this paper, the principal stresses, that is vertical, maximum horizontal and minimum horizontal stresses, and elastic moduli related to rock brittleness, like Young's modulus and Poisson's ratio, can be estimated from wide-angle, wide-azimuth seismic data.

Bridging the Gap: Using AVO to Detect Changes In Fundamental Elastic Constants
TL;DR: In this article, two new seismic amplitude with offset (AVO) equations have been derived, which express the change in AVO in terms of the fundamental elastic rock properties of either Bulk Modulus or Lame's Modulus with Sheaz Modulus and Density.

Recent advances in determination of fracture strike and crack density from P-wave seismic data
TL;DR: The confidence in the ability of AVAZ analysis (amplitude variation with angle and azimuth) to capture information about fractures in a reservoir has steadily increased over the last four years because this technique detected seismic anisotropy in many different reservoirs.
