pdf The possibility of hydrocarbon systems formation by thermometamorphical genesis and the role of hydrothermal super critical fluids
Using the example of supercritical fluids of carbon dioxide and water acssociation from the standpoint of supercritical fluid extraction of organic substances from sedimentary rocks and supercritical cracking of hydrocarbons, the possibility of formation of accumulations of hydrocarbons of magmatic and thermometamorphic genesis is substantiated.

Keywords: supercritical fluids of carbon dioxide and water, formation of hydrocarbon accumulation, supercritical cracking of hydrocarbons.

pdf Petroleum bearing prospect in the south-eastern part of the Ryazan-Saratov fore-deep based on the data of the Svintsov depression
The Saratov Volga region is one of the oldest petroleum regions in the vast Volga-Ural petroleum province, within which numerous gas, gas condensate and oil fields have been discovered in Devonian and Carboniferous terrigenous-carbonate sections. Many fields are multi-layer. However, the geological structure and prospects for discovering hydrocarbon accumulations within the Svintsov depression and its surroundings remain unclear. Based on the analysis of the results of geological exploration of the previous years, we can confidently assume the possibility of discovering oil and gas accumulations in the Devonian terrigenous-carbonate, the prospects of which have been proved everywhere within the adjacent territories of the Ryazan-Saratov fore-deep and Stepnov ridge. The geological characteristics of the Vorobyov, Ardat, Timan-Pash, Semiluky-Sargaev petroleum bearing Formations are presented. A description of the promising identified and prepared structures is given. A geological and economic assessment of the development of promising resources has been carried out.

Keywords: Devonian terrigenous-carbonate sections, oil and gas accumulations, petroleum bearing prospect, Svintsov depression, Ryazan-Saratov fore-deep, Volga-Ural petroleum Province.
