DYNAMIC TO STATIC ELASTIC PROPERTY TRANSFORMS FOR TIV ROCK MATERIAL

摘要

A method of performing an oilfield operation associated with an anisotropic rock, including obtaining a plurality of sonic velocities in an inclined borehole through the anisotropic rock, obtaining a plurality of non-linear equations relating the plurality of sonic velocities and a plurality of anisotropic elastic constants of the anisotropic rock, solving the plurality of non-linear equations for the plurality of anisotropic elastic constants using a Newton-Raphson method, obtaining a dynamic to static transform based on a theoretical model for the anisotropic rock, and performing the oilfield operation based on at least one selected from a group consisting of the plurality of anisotropic elastic constants and the dynamic to static transform.
