Prestack Stochastic Seismic Inversion of the Brenda Field

A020 Prestack Stochastic Seismic Inversion of the Brenda Field G.J. Hicks* (Earthworks Environment & Resources) & A.M. Francis (Earthworks Environment & Resources) SUMMARY 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. EAGE 69 th Conference & Exhibition — London UK 11 - 14 June 2007
