Estimation of Interval Velocity and Attenuation Anisotropy from Reflection Data at the Coronation Field
74th EAGE Conference and Exhibition incorporating EUROPEC 2012
Attenuation can be extremely valuable in characterizing gas sands. In fractured reservoirs, anisotropy can provide additional information about the distribution of fractures. Here, we apply a layer-stripping approach to wide-azimuth P-wave data acquired over a gas reservoir in the Coronation Field, Alberta. The main processing steps involve estimation of traveltimes from the top and bottom of the target layer followed by computation of the interval attenuation using the spectral-ratio method.doi:10.3997/2214-4609.20148453 fatcat:xx5c6blm7fgxviodavz2heqw2i
