Extended Elastic Impedance and its Relation to AVO Crossplotting and Vp/Vs
Extended Elastic Impedance (EEI) has proved to be a highly convenient framework
for seismic AVO studies. The directness of the EEI method is
one of its strengths, making it unnecessary to perform intermediate steps such as examining conventional AVO attributes (eg intercepts
and gradients). This paper, presented by Graham Hicks and Ashley Francis at the EAGE 68th Conference & Exhibition,
Vienna, Austria, 12 - 15 June 2006, explains some of the parallels between conventional AVO and EEI analysis and introduces a new AVO attribute for estimating background Vs/Vp
ratio.
