Abstract

There is always uncertainty in the representative histogram required as an input for geostatistical modeling. This uncertainty should be quantified correctly and incorporated into final modeling because it affects resource/reserve estimation, investment and development decisions. This paper confirms a correct approach of quantifying histogram uncertainty by comparing to reference uncertainty found by an automated scan-based approach. The true variance of the mean is considered as the reference uncertainty. This variance is calculated by finding similar patterns of a data configuration within a large image: The mean of the specified domain is computed for each pattern to attain the true variance of the mean. The correct quantification of histogram uncertainty is defined. The spatial bootstrap provides prior uncertainty that does not consider the domain limits and is not conditioned to the data. This uncertainty is updated in geostatistical modeling to consider the limits and data. The resulting uncertainty closely matches the scan-based approach. A realistic case study is presented.
