Pre-Stack Stochastic Inversion of the Brenda Field
Joint AI-GI stochastic seismic inversion was performed for 100 pairs of equi-probable AI-GI realizations over the Brenda field, which is located in block 15 in the North Sea. Stochastic inversion enables the possible variability in impedance, and hence the uncertainty in lithology and fluid classification, to be explored. These can be represented using probability and connected probability volumes calculated using joint AI-GI thresholds
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.
Our unique stochastic seismic inversion technology has been further developed. To understand the uncertainty in seismic inversion please see our Deterministic and Stochastic Comparison
