Abstract
Fractures in earth formations are a primary source of seismic anisotropy. Anisotropy measurement thus<br>provides a means of fracture characterization. Using physical modeling and field results, this study<br>demonstrates the feasibility of fracture measurements using a monopole sonic logging tool. The method is<br>based on the properties of wave propagation in an anisotropic medium. This paper presents a method of<br>determining shear wave anisotropic parameters from monopole source-receiver systems.
