PP-wave reflection coefficient for vertically cracked media: Single set of aligned cracks
Filip P. Adamus
The main goal of this paper is to analyse the influence of cracks on the azimuthal variations of amplitude. We restrict our investigation to a single set of vertical, circular, and…
On relationship between trigonal and cubic symmetry classes of an elasticity tensor
Filip P. Adamus
In the literature, there is an ambiguity in defining the relationship between trigonal and cubic symmetry classes of an elasticity tensor. We discuss the issue by examining the eig…
On problematic case of product approximation in Backus average
Filip P. Adamus
Elastic anisotropy might be a combined effect of the intrinsic anisotropy and the anisotropy induced by thin-layering. The Backus average, a useful mathematical tool, allows us to…
On constraints imposed on a transversely isotropic elasticity tensor
Filip P. Adamus, Izabela Kudela
We discuss several physical constraints imposed on elasticity parameters of a transversely isotropic (TI) tensor. There are three types of restrictions we investigate; a fundamenta…
On anisotropy parameters and fluid detection in equivalent TI medium
Filip P. Adamus
We consider a long-wave transversely isotropic (TI) medium equivalent to a series of finely parallel-layered isotropic layers, obtained using the \citet{Backus} average. In such a…
On conditions for long-wave equivalent medium to be isotropic and on analysis of parameters indicating anisotropy of equivalent TI medium
F. P. Adamus
In this paper, we consider a long-wave equivalent medium to a finely parallel-layered inhomogeneous medium, obtained using the Backus average. Following the work of Postma and Back…
