Stress identification with an azimuthal inversion technique - a case study for a clastic oil field.

Azimuthal inversion is state-of-the-art inversion technology for stress and fractured reservoir characterization and detection in anisotropic media. This technology requires a wide-azimuth seismic survey and careful azimuth dependent processing with noise attenuation. In this paper, the influence of noise attenuation on the reliability of anisotropic inversion results is discussed. The implementation of this technology for the understanding of horizontal stresses and the verification of the results with well data and microseismic will be presented.
