A Markov-Gauss algorithm for blocking well logs
Paul N. Chouinard, Ken V. Paulson · Geophysics · 1988
Abstract A characteristic common among petrophysical sections is "blockiness," which results from the high probability that a given rock and the rocks above and below it are all of the same type. Furthermore, if a new rock type is encountered, the next rock's type is dependent upon this new type and not on a previous type. This suggests that a Markov chain would be an appropriate basis for modeling such physical parameters as acoustic impedance, electrical resistivity, etc.
