The 15 contributions, of which five are on applications in petroleum science and ten are on mining geostatistics, were presented at the 31st International Geological Congress, held in Rio de Janeiro, Brazil, from 6th - 17 August, 2000. Stochastic simulation was the key theme of these case studies. A wide range of methods was used: truncated Gaussian and pluriGaussian, SIS and SGS, Boolean methods and multi-point attractors. The five contributions on petroleum science focus on different aspects of reservoir characterization. All use stochastic simulations to generate 3D numerical models that reproduce the key features of questions such as reconciling reserve estimates with production figures. None of the contributions discuss theory; instead they show readers how to incorporate geology into geostatistical case studies in a meaningful way.
