Shear velocity logging in slow formations using the Stoneley wave.

Abstract

Applies an iterative, linearized inversion method to Stoneley waves recorded on acoustic logs in a borehole. The objective is to assess inversion of Stoneley wave phase and group velocity as a practical technique for shear velocity logging in slow formations. Concludes that Stoneley-wave inversion constitues a practical, indirect, shear-logging technique for slow formations.-from Authors
