SABININ, V  y  CHICHININA, T. AVOA technique for fracture characterization: resolving ambiguity. Geofís. Intl [online]. 2008, vol.47, n.1, pp.3-11. ISSN 2954-436X.

A new computational technique of AVOA analysis (Amplitude Versus Offset and Azimuth) is developed which resolves an ambiguity in fracture-direction estimation. It analyzes a third term of Rüger's approximation for P-wave reflection coefficient to distinguish symmetry-axis and fracture-strike directions. The technique is tested on synthetic and field data.

Palabras llave : AVOA; HTI media; seismic anisotropy; fracture-reservoir characterization.
