16. THE SONIC OR ACOUSTIC LOG 16.1 Introduction

(16.4) where g is the shear strain. The application of the shear stressP s causes the development of a shear strain g. Detailed analysis of the velocity and slowness of P-waves in a material shows that; 3 for solids 4 r + m = K VP (16.5) for fluids r K VP = (16.6) 16.2.2 Reflection and Refraction
