Over the last few years there has been significant interest in the analysis of open fluid-filled fractures from P-wave azimuthal anisotropy. This paper presents the results of a recent study on the Tin FouyC Tabankort Field, in the Illizi Basin (Algeria). The goal of this study was to characterise the seismic anisotropic fractures from Previous HitRMSNext Hit Previous HitamplitudeNext Hit maps on a small volume of the field. Using an integrated workflow that combines azimuthal-friendly processing with a proprietary geostatistical decomposition technique, we have obtained robust quantitative estimation of the anisotropy attributes. A good correlation was observed between the extracted fracture intensity and orientation, the seismic coherency maps and the fault interpretation. Such results contribute to a better evaluation of the fracture networks.
