pdf  Peculiarity of spatial occurrence of Permian bitumens and more deep oil pools on the Tatarstan Republic territory
The regularities of formation and spatial occurrence of heavy super-viscous oils and natural bitumens on the Tatarstan territory are considered. It is shown that forming the oil pools in Middle Carboniferous deposits and the accumulations of Permian bitumens are connected with fluid vertical migration from Lower Carboniferous deposits. In all 450 oil-bitumen accumulations of a different rank with total resources of 1.4-7.0 billion t are established. Their development is envisaged in the program for the period until 2020. This program envisages a large volume of exploration, introducing the progressive methods of development with using horizontal wells.

Key words: natural bitumens, heavy oils, bitumen shows, vertical migration, South Tatar arch, Melekesskaya depression.
