Abstract

A seismic reservoir characterisation is method is explained and used to build a 3D facies model for the deep offshore Girassol field, Angola. This 3D seismic facies model is updated using time-lapse attributes derived from 2 repeat seismic surveys. During the update, non-reservoir cells that proved to have shown production induced impedance changes are reassigned to a most probable reservoir facies. Using the updated facies model in history matching, the breakthrough time of a injector/producer pair is significantly improved when compared to the initial reservoir model.
