Some problems of geological model qualitative assessment

Authors: A.V. Getman (Sintez Petroleum CJSC, RF, Moscow), V.L. Kiselev, A.S. Alekseev, V.P. Volkov (TING CJSC, RF, Tyumen), I.F. Ishmuratov (Negusneft JSC, RF, Radyzhny)

Key words: geological modeling, ranks variograms, geological and technical model, stochastic simulation method, the cube lithology, lithological discontinuity, ruggedness.

The influence of discontinuity characteristics in reservoir cube of the geological model on the result of filtration model and regulation of quality control characteristics of the geological model was viewed in the paper. Also the issue of correctness assessment of variograms settings raises. This aspects are not controlled the applicable regulatory documents for the permanent construction of geological and engineering models.
