Abstract
Conducted long-term studies at Kuyumbinskoe field enabled to form an idea of its geological structure, conditions of formation, the type of collectors and the methods of analysis. The Deposit is confined to the major erosional ledge Riphean carbonate rocks with well-developed system of fissures formed during the long pre-Vendian erosion. Fracture of the matrix and prolonged exposure to the atmospheric processes contributed to the supergene transformation of the carbonates in the area of fractured-cavernous karst reservoir to a depth of 150 m. The scheme of their formation and preservation. For a detailed study of the internal structure of reservoirs in the company “Slavneft-NPC” on the basis of borehole and 3D seismic data created a unique technology for studying and modeling complex Riphean reservoirs currently used in the placement of wells.
