Claim One:
1. A process for calculating a meshed description of a realization of a reservoir, the realization comprising a plurality of stratigraphic surfaces, the process comprising: (a) obtaining a reference realization of the reservoir, the reference realization comprising the stratigraphic surfaces; (b) obtaining a meshed reference description for the reference realization, the reference description comprising a plurality of planes, at least some of the planes describing the stratigraphic surfaces, each of the planes comprising a plurality of points; (c) obtaining at least two particular surfaces of the stratigraphic surfaces of the realization corresponding to two stratigraphic surfaces of the reference realization; and (d) for two homologous points of the plurality of points of two particular planes of the plurality of planes describing the two stratigraphic surfaces of the reference realization, i. determining two points underlying the two particular surfaces of the reference realization, ii. calculating displacements of the two underlying points in transit of the two stratigraphic surfaces of the reference realization to the corresponding particular surfaces of the realization, iii. selecting the displaced underlying points as two homologous points of the planes of the meshed description describing the particular surfaces of the realization, and iv. determining planes of the meshed description by an interpolation between homologous points of the planes of the meshed description describing the particular surfaces of the realization.
