A system configured to generate a geostatistical model of a geological volume of interest, the system comprising: one or more processors configured to execute computer program modules, the computer program modules comprising: a conditioning information module configured to obtain conditioning information associated with the geological volume of interest, wherein the conditioning information includes information derived from measurements made at or near the geological volume of interest; a process model module configured to generate a process-based model of the geological volume of interest, wherein the process-based model is conformed to the conditioning information associated with geological volume of interest; a statistics module configured to generate statistics from the process-based model that are faithful to the process information in the process-based model, wherein individual ones of the statistics are determined locally within the process-based model such that the value of a given statistic varies as a function of location within the process-based model; a statistical model module configured to generate a geostatistical model of the geological volume of interest that is constrained by the statistics generated by the statistics module; characterized in that it further comprises a match quantification module configured to determine a match metric that quantifies a closeness of match between the process-based model generated by the process model module and the conditioning information associated with the geological volume of interest; and a match verification module configured to verify, based on the match metric, that the closeness of match between the process-based model and the conditioning information meets a match threshold, wherein the match quantification module is configured such that the match metric is determined locally across the process-based model such that the match metric varies as a function of location in the process-based model. one or more processors configured to execute computer program modules, the computer program modules comprising: a conditioning information module configured to obtain conditioning information associated with the geological volume of interest, wherein the conditioning information includes information derived from measurements made at or near the geological volume of interest;
