Abstract

Conventional reservoir characterization using geostatistical techniques to compute facies and porosity distribution usually begins from an estimation of the acoustic impedance. This impedance distribution is obtained using inversion technique as the stratigraphic inversion which works on prestack reflection seismic data [Tonellot & al., 2001]. The aim of this work is to take advantage of Amplitude versus Angle (AVA) inversion done after prestack depth migration to perform a depth domain impedance estimation constrained by AVA attributes. We propose to use geostatistical impedance simulation constrained by the migrated common image gather (CiG) and the skeleton of the structure obtained during the AVA inversion as well as the intercept and the slope sections.
