According to the results of the Project Comprehensive Study of the Sedimentation Basins of Kazakhstan was substantiated the high prospect of Paleozoic deposits in the west of the Turan Plate (Ustyurt-Bozashi and Mangyshlak). Also were obtained new data on the nature of the occurrence of the Paleozoic stratum in the context of all basins located on the east of Ural folded systemAkchulakovand etc.; 2009-2013). These pools are part of various structures of the first order. A high assessment of the prospects and the forecast potential of sedimentary basinsis shown, obtained as a result of the study and attraction of the Paleozoic sequence as the most important area of research. Almost all of the basins, including the Caspian Sea, Paleozoic complex is the main direction of exploration. Accordingly, the need to increase the depth of exploration is one of the main results of the Project, which is a condition for an objective assessment of the prospects and potential of the territories. It is noted that there are favorable conditions for the substantiation of the priority objects in the Paleozoic, taking into account the already established fund of structures. The study of large depths in this case makes it possible to count on wide opportunities for forecasting and discovering new large deposits occurring in more complex geological conditions. It should be assumed that large deposits are associated with objects of the unconventional types - non-anticlinal type. Due to the lack of data the position of the Paleozoic roof in Ustyurt-Bozashi and Mangyshlak was ambiguous; In the section of the Uzen-Karamandybas-Tenge zone were obtained high dynamic characteristics, was made a forecast in the Paleozoic strata of the stratification and in the large and prospective search elevations. The regularities of petroleum potential established in the west of the Turan Plate provide certain material and opportunities for conducting regional and area studies in the south-eastern basins in order to preliminarily assess the full-fledged identification of the Paleozoic sequence and justify its perspectivity. The degree of study of the Paleozoic strata of sedimentary basins in the south-east is at the initial stage of study. The Aral, South Torgai and Zaisan basins stand out more “characteristic”. They have the prerequisites for the selection of search objects and the detection of new clusters of hydrocarbons. The study of the Paleozoic strata in the large territory under consideration makes it possible to substantiate a regional model for its formation and tracking, to clarify the deep structure of sedimentary basins for solving a number of issues of fundamental importance.......
