Summary:
On the core of the Ignyalinsky, Tympuchikansky, Vakunaysky and adjoining licence blocks, the comprehensive research program of the secondary processes of Nepskaya suite was carried out for the first time. For each of the facies, the reservoir quality, mineral and grain composition, the salinization degree of rocks by halite/anhydrite and carbonatization, recrystallization have been determined. The basic hypotheses of secondary processes was formed. Hypotheses were integrated with geophysical data. The forecast of collectors and zones of secondary mineral crystallization was made.
