pdf Stratigraphic features of Jurassic terrigenous strata belonging to the Central part of the Chardzhou step and their relationship with pre-Jurasic formations
When carrying out exploration activity for oil and gas in the strata of the Jurassic terrigenous formation in the study area, it is necessary to establish the age equivalence of stratigraphic units. The results of a detailed study of the terrigenous rocks composition, lithofacies and stratigraphic characteristics of Jurassic terrigenous section are presented. The influence of pre-Jurassic formations on the genesis of terrigenous strata, due to the strong alteration of the surface of pre-Jurassic section, which determined the facies and stratigraphic characteristics of the terrigenous formation, as well as the inheritance of the relief and the distribution of thicknesses of terrigenous cover, is considered.
The studied patterns make it possible to determine the temporal and spatial distribution and the relationship of reservoirs and seal rocks in terrigenous Jurassic strata on the territory of the Central part of the Chardzhou step and make it possible to effectively solve theoretical and practical problems of oil and gas geology of the Republic of Uzbekistan.

Keywords: Jurassic terrigenous formation, lithofacies characteristic, stratigraphic characteristic, oil and gas geology, Central part of the Chardzhou step, Republic of Uzbekistan.

pdf Formation and distribution of heavy oils and bitumens in the Bukhara-Khiva region
Within the Bukhara-Khiva petroleum region, in addition to oil and gas fields, a large number of accumulations of solid bitumen, heavy and high-viscosity oils have been discovered. The geological structure and bitumen and oil content in the stratigraphic range of distribution of these accumulations - from the Paleogene to the Paleozoic are considered. Within the Zirabulak-Ziaetda mountains, six bituminous bearing areas have been identified: Mayzak, Sukaity I, Sukaity II, Chadyr, Zapadnoe and Karaiz. According to them, forecast resources are calculated. Also known is the Karaiz uplift with numerous bituminous bearing areas. The distribution surface is more than 60 square kilometers. Рromising resources of bitumen in C3 category were estimated for the selected objects. Within the Bukhara step, the predicted resources of bitumen areas are more than 352.0 million tons. This gives grounds for setting up prospecting and exploration activity and organizing experimental sites for the development of unconventional methods for hydrocarbons extracting.

Keywords: bitumen, heavy oils, stratigraphy, predicted resources of bituminous accumulations, setting up exploration activity, Bukhara-Khiva petroleum region.

pdf Geological aspects influencing the final gas recovery factor of Vostochny Berdakh - Uchsay field
Depending on the peculiarities of the geological, hydrogeological, technical and economic conditions for the development of gas and gas condensate fields in the Ustyurt petroleum region, the final gas recovery from terrigenous Jurassic reservoirs can vary widely.
The increase in the final gas recovery is one of the main issues of the rational development of gas and gas condensate fields and depends on geological and technological factors.

Keywords: Jurassic terrigenous reservoirs, gas recovery factor, Vostochny Berdakh-Uchsay field, Ustyurt petroleum region.
