Abstract

Modelers are faced with a variety of challenges when building geocellular models. One significant challenge centers on facies modeling. Practitioners are driven by the depositional models they understand, but all too often the mathematical methods they use are less understood. The selection of a simulation algorithm and the methods used to introduce trends and conceptual geologic information are two potentially significant areas in whichproblems canarise. To address these issues, the authorspropose common facies simulations algorithms be combined with the use of a lithotype proportion matrix (LPM).
