hTe characteristic feature in the development of today's petroleum industry is that exploration activity is directed towards the search for oil and gas in sea shelf areas. Sea shelf areas of the U.S.S.R. have depths down to 500 m and total about 7600000 sq km.
The present report deals with the description of the geological structure of shelves of the U.S.S.R. and evaluation of their oil and gas prospects. The report and maps have been compiled using all data on shoreline dynamics, sea bottom relief and bottom Sediments as well as on the basis of analysis and extrapolation of data on geological structure of adjacent land areas. Of intra-continental seas of the U.S.S.R. the most certain prospects are associated with the Caspian Sea. The north-western part of the Black Sea and the folded area lying in the seaward extension of the Kolhidskaya depression are the most interesting parts in this region in the search for oil and gas. Drilling operations are expected to be commenced on a number of structures in the Sea of Azov. It is possible to discover oil and gas within the limits of the shelf of the Baltic Sea. The most promising areas are those associated with the northern and eastern seas of the U.S.S.R., i.e. with depressions adjacent to the proved oil and gas bearing regions on the continent. The geological structure and the oil/gas prospects of the outer depressions stretching along the outer shelf margin are still be be elucidated. by N. A.

Ce qui caractérise l'industrie pétrolière moderne c'est l'envahissement des aquatoriums des mers et des Océans pour l'exploration de pétrôle. La surface totale des Schelfs de l'Union Soviétique de profondeur à 500 m s'élève à 7600000 km2. Ce rapport donne la description de la structure géologique et l'évaluation des perspectives des Schelfs de l'U.R.S.S. au point de vue de la présence du pétrôle et du gaz. Les cartes et ce rapport sont faits d'aprés nos connaissances actuelles sur la configuration des côtes, rélief du fond, précipitations et sur la base de l'extrapolation des données sur la structure des régions proches, aux Schelfs.
La mer intercontinentale la plus perspective en Union Soviétique c'est la mer Caspienne. Le secteur Nord-Ouest de la Mer Noire et la zone plissée qui est le prolongement de la dépression de Kolkhide sont les p
