A Reliable Analysis of Azimuthal Related Information for Fracture Detection

Azimuthal seismic analysis is an important step in the analysis chain of seismic data in carbonates and shales. However, the azimuthal information derived is very sensitive to many aspects of the data and of the analysis process. In this paper we define the concept of reliability, a measure of the quality of the azimuthal analysis, analyze some of the major factors affecting it, and show our approach to how a reliable analysis should be performed and presented.
