Abstract
Summary
In this paper a new procedure to estimate the Thomsen parameters ε and δ in VTI (Vertical Tranversely Isotropic) media is presented. The approach used in this work exploits the angles of the ray segments computed by the anisotropic ray tracing in travel time tomography using direct, reflected and refracted arrivals. The reliability of this technique is demonstrated by two synthetic examples related to transmission tomography (cross-hole) and reflection/refraction tomography.
