Lithological-stratigraphical and facial characteristics of the Middle Jurassic strata belonging to the Berdakh-Takhtakair uplift of the Ustyurt bearing petroleum region
At present, within the Berdakh-Takhtakair uplift, as well as across the Ustyurt bearing petroleum region (Republic of Uzbekistan) as a whole, geological exploration is intensifying to discover new hydrocarbon accumulations in Middle Jurassic strata composed of terrigenous rocks of various origins. This article presents the results of lithological and facies studies that established the stratigraphic features of Middle Jurassic sections in the study area and identified the patterns of landscape evolution during the Middle Jurassic sedimentation stage. The recognized patterns make it possible to determine the distribution of sedimentary rocks within the Middle Jurassic by defining the genetic conditions of their accumulation and identifying lateral facies variability. This enables a reliable prediction of the spatial localization of reservoir rocks and cap rocks.

Keywords: Middle Jurassic terrigenous rocks, lithofacies studies, Berdakh-Takhtakayr swell, Ustyurt oil and gas region, Republic of Uzbekistan.

pdf  Compositional features of the Lower Permian sequences revealed in the Satbhai well 1 (Southern Ustyurt)
This article gives the detailed characteristics of Lower Permian section which was drilled by exploration Satbay-1 well. Based on the complex analysis of geological and geophysical data related to the drilled wells within the limits of the Shordja uplift authors identified a lot of petrogenetical, mineralogical - petrographical features and geochemical composition of the studied section.

Keywords: petrogenetical structure, mineralogical and geochemical composition, Lower Permian, Southern Ustyurt.
