pdf Geothermal characteristics of Jurassic strata of the South-Western Gissar petroleum region
The identified industrial hydrocarbon accumulations of the South-Western Gissar petroleum region (Republic of Uzbekistan) are stratigraphically associated with sequences of the Middle-Upper Jurassic carbonate strata. The geothermal characteristics of groundwater in the Jurassic strata have a wide range of variations from the southwest to the northeast, depending on the depth of the sedimentary cover. This is also associated with the lithological-stratigraphic and tectonic structure of the region.
The features of changes in geothermal conditions with depth and area are considered. A comparative analysis of geothermal indicators is carried out: temperature, geothermal gradient, geothermal stage. Based on factual materials, schematic maps of changes in modern temperatures in the regional plan were constructed for the XVa and XV levels of the Jurassic strata of the South-Western Gissar petroleum region.

Keywords: Jurassic strata, carbonate strata, hydrocarbon accumulation, geothermal gradient, geothermal stage, South-Western Gissar petroleum region, Republic of Uzbekistan.
