Riphean capacity that was lost for decades (based on the examples of the Eastern Siberia Carbonate Reservoirs)

Upon examining the wells core material of the involved section except for the fractures in the Ripheangeological section there were also found cavernous intervals and dissolved cavities. We have succeeded indescribing the analysis of the core X-ray tomogram data as a statistical model.There has been performed themathematical modelling of the seismic wave field behaviour for the cavernous layer. There has been alsodiscovered the theoretical possibility of the such layers extraction in the seismic data. The theoreticalcalculations have been approbated on the real data. There has been showed the potential of the seismic datausage for the thin and high-capacity cavernous interbeds extraction.
