Nonlinear Semblance Processing For The Evaluation Of An Acoustic Altered Zone Around The Borehole

Nonlinear Semblance Processing For The Evaluation Of An Acoustic Altered Zone Around The Borehole

This paper describes a simple method to evaluate an acoustic altered zone around the borehole using an array of sonic waveforms. The method is based on a semblance velocity analysis and a nonlinear travel time window is introduced. On the assumption that a velocity gradient of the altered zone ma...
