Glossary:Conditional simulation

A geostatistical method to create multiple equally probable images of a regionalized variable on the basis of a spatial model. It is conditional only when the actual control data are honored. Conditional simulation is a variation of conventional kriging or cokriging. By relaxing some of the kriging constraints (e.g., minimized square error), conditional simulation can reproduce the variance of the control data. The final "map" captures the heterogeneity and connectivity that most likely is present in the reservoir. Post-processing conditional simulation produces a measure of error (standard deviation) and other measures of uncertainty, such as isoprobability and uncertainty maps.
