Simulation model calculation is a base method that used for the efficiency of development strategy calculations it is necessary to design geological and simulation models within which are defined reservoir properties and heterogeneity. Estimation of influence on reservoir properties of various kinds of geological uncertainties will allow defining more effective development strategy. Achimov Formation of Vingapur Oil Field was considered in current study the Northern part field nowadays is quite attractive for the development of this formation. The aim of work was complex investigation of petrophysical properties for the purpose of it prognosis across the field and the effect of geologic uncertainties on production assessment. On the first step was studied the western part of the field where core data are available, next was developed algorithm for the properties prognosis and eventually was constructed geologic and reservoir simulation models for the investigation of the effect of geologic uncertainties in Northern part. Petrophysical model of the reservoir where for the evaluations was applied method of Rock Types identification, in addition to this, Hydraulic Flow unit approach was also employed, that makes possible reservoir properties estimation in less explored areas of the field where core has not been retrieved.
