Abstract

The rationale was to model a set of seismic responses that were expected from a regional point of view, and then deduce whether fluid effects were big enough to justify for AvO inversion. For top carboante interfaces, modelling results implied that fluid effect had more impact on M when the overburden rock was soft shale. There were two top carbonate interfaces with soft overburden shale that showed big difference in M when substituted with gas. This observation supported the modelling result. For the other part of modelling, gas-water contact could possibly be differentiated from intra carbonate, but most differences were in the L domain. AvO inversion was not necessary to differentiate gas-water contact. In conclusion, there were fluid separations in the AvO modelling results, but the extra values that an AvO inversion can bring are questionable.
