The most useful way to validate a predictive scheme is to compare its results against actual performance. While this approach has enjoyed some success, the interpretation of any reservoir process is complicated by many operational, reservoir and subjective issues. These issues mean that the process performance is rarely clear, and consequently the success of the prediction is always in doubt, no matter how closely the prediction agrees with performance. The work described in this paper adopts another means of validation: comparison of a highly detailed deterministic simulation against the results generated from conditional simulation (CS). Results show that, although it is highly flexible and generates realistic heterogeneity, CS must be tailored to the specific geological environment for best agreement with the deterministic simulation.
