【 摘 要 】

This paper aims to study the variation of tank thickness using geostatistical methods. The tank was divided into three separated zones. Experimental variograms were constructed to characterize the spatial variability of the measured thickness of the tank. Spherical and exponential variogram models were fitted to the experimental variograms. The selected models were used to construct a corrosion map using the ordinary kriging for the three different zones.
