Application of geostatistical methods to study geological structure of complex oil production zones
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.
