DETAILED CORRELATION OF WELL SECTIONS – THE BASIS FOR DEFINITION OF WASH-OUTS AMPLITUDES DURING DEPOSITIONAL BREAKS AND FORECAST OF OIL-AND-GAS-BEARING FORMATIONS DISTRIBUTION (BY THE EXAMPLE OF THE KAMO ARCH)

N. V. Melnikov

Member and layer by layer dissection of the Oskoba, Katanga and lowermost strata of Soba formations (Vendian) in the wells of the central Kamo arch (Yurubchen-Tokhomo and Omoro zones of oil and gas showings) is given. Amplitudes of wash-outs during pre- Danilovo and pre- Soba depositional breaks are substantiated. Territories of occurrence of productive and prospective for oil and gas formations of B-VII and Preobrazhenka ones in the Katanga Formation, B-VII -I (Kamo) in the Oskoba Formation are determined. The position of the Preobrazhenka stratum in the lower Katanga Formation is shown.

Key words: Kamo arch, breaks, wash-outs, Katanga and Oskoba formations of Vendian, members, layers, productive formation.
