Resumen
SABININ, Vladimir. AVOA techniques for fracture characterization. Geofís. Intl [online]. 2014, vol.53, n.4, pp.457-471. ISSN 2954-436X.
Different aspects of computational techniques for AVOA analysis (Amplitude Versus Offset and Azimuth) for fracture characterization are considered, in particular: using amplitudes instead of reflection coefficients, smoothing seismic data, and numerical methods for estimation of fracture directions. A new computational method and a new filter for smoothing are suggested. The different computational methods are compared in synthetic reflection surface data with noise, and without noise. Properties of the numerical methods in dependence on different sets of azimuths and offsets are obtained. It is shown a superiority of the new method.
