AB: The spatial permeability distributions of natural media are strongly heterogeneous. In a geostatistic model, the heterogeneity is often characterized by its stochastic properties: mean, variance and correlation length. The correlation length can only be obtained in field by large amount of measurements. In many field conditions, these measurements are not available, so the correlation lengths are assumed based on limited data. In this study, a novel approach is developed to estimate the correlation length of a medium permeability from field tracer test data and limited permeability measurements. The underlying idea of this approach is that the more accurate estimation of geostatistic properties will lead to a more fast and accurate convergence of measurement and simulation results. Our result shows this approach can well capture the medium permeability­_s correlation length. The influence of the amount of permeability measurements on the accuracy of estimation is also discussed.
