A MARKOV CHAIN MODEL FOR SUBSURFACE CHARACTERIZATION: THEORY AND APPLICATIONS

Abstract

This paper proposes an extension of a single coupled Markov chain model to characterize heterogeneity of geological formations, and to make conditioning on any number of well data possible. The methodology is based on the concept of conditioning a Markov chain on the future states. Because the conditioning is performed in an explicit way, the methodology is efficient in terms of computer time and storage. Applications to synthetic and field data show good results.
