Fracture characterization based on the concept of seismic anisotropy has become widely used in industry, particularly through the interpretation of azimuthal AVO or AzAVO analyses. However, the integration of seismic anisotropy attributes with other seismic attributes (e.g. curvatures, dips, etc.) and with borehole fracture data faces challenges because of resolution, detectability, sensitivity issues, as well as overburden effects. In this paper, we present results from a systematic modeling study to address some of these issues. The modeling results presented here have highlighted the complexity of azimuthal anisotropy, and can help to eliminate uncertainties in interpreting seismic anisotropy attributes in terms of natural fractures.

The seismic data examples illustrate the strong diffraction response of subsurface discontinuity or heterogeneity.

The direct detection of hydrocarbons with the seismic technique is one of the main goals of current geophysical research. Amongst the many direct hydrocarbon indicators which have been proposed, the AVO technique has received by far the greatest attention in the literature. The technique has inspired confidence in large part through its ability to relate the observed phenomena directly to rock and fluid properties through robust seismic modeling and rock physics relationships.
