ABSTRACT:
Embodiments of the present invention provide a method and apparatus for geomodel uplayering. The method may include calculating one or more vertical cell property means for cells within a three-dimensional geomodel, generating at least one vertical mean trend sum utilizing the vertical cell property means, grouping cells utilizing at least one of the vertical mean trend sums to define a plurality of cell regions, calculating at least one horizontal cell property variance for at least one of the cell regions, and forming a plurality of cell blocks utilizing one or more of the horizontal cell property variances.
