A finite-difference method of numerical simulation of sonic logging has been developed and implemented. The very general statement is considered: the surrounding medium is allowed to be 3D heterogeneous and a source can be located at any point inside or outside the well. To provide a maximally preci

## Abstract It is well known that standard finiteβdifference schemes for singular boundary value problems involving the Laplacian have difficulty capturing the singular (πͺ(1/__r__) or πͺ(log __r__)) behavior of the solution near the origin (__r__ = 0). New nonstandard finiteβdifference schemes that
