<p>The computer-based method involves defining at least one geographical zone (Z) within underground medium by selecting a set of cells of geological model. An average proportion in the zone is determined for k facies using optimization process, allowing the difference to be reduced. The proportions of k facies in each cell of geographical zone are modified, in which k is a predetermined value. A computer is used to simulate a new geological model constrained by facies proportions which are modified, and to optimize development of underground medium by using the simulated model. The proportions of the k facies in each cell of the geographical zone are modified with a block indicator co-kriging method constrained by the average proportions. A value of 0 is assigned to any modified proportion which is less than 0. A value of 1 is assigned to any modified proportion greater than 1. All proportions of the facies, which are modified, are normalized so that in each cell a sum of the proportions of the facies is equal to 1.</p> |
