Azimuthal behavior of P-waves in horizontal transverse isotropy

ABSTRACT

The behavior of P-wave reflection varies with azimuth for rocks whose material properties vary with azimuth. I study the effects of horizontal transverse isotropy in P-wave reflection patterns on a simple homogeneous model, a finely fractured shale overlying an isotropic chalk with varied amounts of fracturing. I have produced 2-D reflectivity maps that clearly illustrate the azimuthal behavior of P-waves as the aspect ratio, volume density and filling material of the cracks are varied.
