Abstract
In truncated gaussian simulations, the lithofacies are not simulated directly: a stationary gaussian random function is simulated first, and is then transformed into the lithofacies variable by truncation. For example, if we want to simulate two lithofacies, F1 and F2, a very intuitive way to transform the simulated gaussian variable into facies values is to say “if the numerical value of the simulated gaussian is lower than the number t1, we obtain the first facies F1; otherwise, we obtain the second facies F2”. The value t1 is called a threshold.
