pdf Influence of correlations on results of probabilistic geological modelling
The paper deals with utilization of correlations between volumetric parameters in probabilistic geological models. When creating 1D probabilistic models in which uncertainties assessment is realized by multiplication of distributions, interrelationships between parameters often are not considered well that cause incorrect results of hydrocarbons-in-place estimation and adoption of non-optimal decisions. The degree of interdependencies influence on the modelling results is demonstrated, as well as cases of typical correlations that should be analyzed in probabilistic modelling are described.

Keywords: correlations between volumetric parameters, interdependences between parameters, geological uncertainties, probabilistic geological model.
