Geostatistics is the statistics of spatially or temporally correlated data. Thickness of a stratigraphic unit is spatially correlated; at a particular locale, the thickness is probably constant, but the similarity in thickness varies with distance. In the subsurface, thickness can be estimated from that observed in nearby wells. The assumption that a variable like thickness is correlated with itself in space—i.e., autocorrelated—lies at the heart of contour mapping, whether by computer or by hand.
