The Timas-Pechora petroliferous province (TPP) is a marginal system of the East Europe platform and includes the Pechora plate and Pre-Ural depression. It contains alternative mobil and stable blocks which determine the tectonic and oil and gas regions for six petroliferous complexes (PGC) in the sedimentary cover. Six petroliferous regions are in TPP. The regions consists of areas as well as zones of oil and gas generation and accumulation. A wide stratigraphic and lithological spectrum (from Ordovician to Triassic) of commercial, multizone oil and gas general and accumulation is in every region in carbonate and terrigenous reservoirs with depths ranging from 500-600 m to 5 km and more. The generation potential of TPP was determined by comparative analysis of geochemical indices of humic and sapropel organic matter with simultaneous determination of catagenesis grade of rocks and organic matter. The main zones of oil generation (with lower limits 3.5-5.3 km for different PGCs) and gas generation also was determined. The areas of oil and gas generation and accumulation were separated on the basis of production-genetic indexes as well as by generation potential. Accumulative possibilities of natural reservoirs in different kinds of traps were evaluated qualitatively and quantitatively.
