GEOLOGICAL AND GEOCHEMICAL AND ECONOMIC ASSESSMENT  OF PETROLEUM POTENTIAL SEARCHES  OF BASEMENT FORMATIONS OF WESTERN SIBERIA  AND THE CHOICE OF PRIORITY INPUT STRUCTURES IN EXPLORATION DRILLING

V.L. Shuster, S.A. Punanova,  A.V. Samoilova

The geological and geochemical and economic assessment of prospects of oil-and-gas content of basement formations of  Western Siberia is given. On the basis of these factors the choice of sequence of input of perspective objects in prospecting drilling  is carried out. Methodical approach to probabilistic estimation of oil and gas prospects of local objects is to define the integral probability of main geological and geochemical factors, affecting on the formation of oil and gas accumulations in fractured-cavernous rocks. The program “Choice” was used. The most important factors are reservoir-rocks, flyuidoupors, traps, contents and type of organic substance of maternal thicknesses, generation of hydrocarbons.
