Characterization Of Subsurface Heterogeneity: Integration of Soft and Hard Information using Multidimensional Coupled Markov Chain Approach

We developed a 3-D CMC model and corresponding software called CMC3D. It is an extension of previous work by Elfeki and Dekking (2001). (The software is available directly from the authors.) A brief algorithm has been presented here. We also provided improved schemes for the CMC 2-D conditioning. Monte Carlo simulations show that our model is stable for most cases. The 2-D application on the MADE site shows that the model has promise for delineating the complex geological structure of an aquifer, even with only sparse data.
