Abstract
Siberian craton is one of the most important mineral resourses bases in Russia. However, because of compound geological structures, the area is not explored properly. Even the most examined areas have unresolved geological problems. One of these is the correct prediction of oil-and-gas presence and reservoir quality discrimination of terrigenous deposists in Vendian oil producing play.
This article focuses on development of methodical approach and complex log interpretation algorithms for reservoir quality discrimination, saturation estimation and determination of porosity, shaliness and oil saturation factor in licensed area of the Nepsky arch central part of Nepsko-Botuobinskaya anteclise. In practice, applying of this methodical approach enabled to determine reservoir properties and to increase the accuracy of porosity and permeability estimation from the logs data.
