STRUCTURE MODELS AND PETROLEUM POTENTIAL QUANTITATIVE ESTIMATION OF THE VENDIAN TERRIGENOUS MACROSEQUENCE REGIONAL RESERVOIRS OF THE PREDPATOM REGIONAL TROUGH (SIBERIAN PLATFORM)

G. G. Shemin

The Predpatom Regional Trough is located in the southeastern part of the Siberian Platform along the operated oil pipeline «Eastern Siberia – Pacific Ocean». This is potentially a large object of hydrocarbon reserves development. It is characterized by a low degree of study by seismic exploration and drilling and complex structure. It hinders the development of structure models of Vendian-Lower Cambrian sediments and the reliable assessment of their petroleum potential. The models of seal structures and permeable sequences of the Vilyuchany, Lower Nepa, Upper Nepa and Tira regional reservoirs of the Vendian terrigenous macrosequence are considered. The results of the quantitative estimation of the prospects for oil and gas are presented.

Key words: Predpatom Regional Trough, reservoir, permeable sequence, seal, pay zone, quantitative estimation, petroleum potential, reference block, estimated block, resources, reserves, oil, gas, condensate.
