The Soviet Union has announced the start of development of natural bitumen beds in the Tatar oil-bearing province of the Volga-Urals. A special extraction agency, Tatneftebitum, has been established as part of Tatneft', the Tatar Oil Administration, and the first dozen tons of molten bitumen were said to have been extracted by in-situ heating. Geologically, the Mordovsko-Karmalka deposit is situated on the eastern margin of the Melekess depression and the western margin of the South Tatar arch, with the bitumen occurring in lenticular accumulations within sandstones of the Ufa stage of the Upper Permian. The bitumen is of the maltha type, between conventional petroleum and asphalt, and the deposit has a shallow location, at a depth of 80 meters. Soviet interest in natural bitumens is evidently associated with the problem of developing additional resources of conventional oil. Natural bitumens are being viewed in the Soviet Union not only as a possible substitute for conventional oil, but as a raw material in its own right, with specific applications in the present economy (road construction, insulation and anticorrosion applications, the derivation of certain chemicals). 3 figures.
