Abstract

This paper presents criteria for evaluation of heterogeneity, particularly, a set of normal distribution features exhibiting steady-state behavior.

Construction and analysis of histogram and variogram as well as calculation of variation coefficient have been shown to enable real-time assessment of the steady state of geological random variables within the region of interest. A decision on application of stochastic approaches during three-dimensional simulations of complex reservoirs is made based on meeting steady state criteria.

Key words:

heterogeneity, random variable, steady state, normal distribution, histogram, variogram, coeffitient of variation
