It is no secret that the Eastern Siberia is one of the key regions of Russia for hydrocarbons production. One of the fundamental regions in this direction is the Krasnoyarsk Krai. It is on the territory of the Krasnoyarsk Krai that interesting deposits are located with good oil and gas potential. Especially researchers of petroleum geologists are attracted by the deposits with a carbonate type of reservoir. Their share in the Krasnoyarsk Krai accounts for nearly 40 % of the main deposits. The authors of the article will pay attention to the Riphean carbonaceous reservoirs of the Tersko-Kamovskiy LU of the Yurubcheno-Tokhoma oil and gas accumulation zone. The considered Riphean reservoir of the Yurubcheno-Tokhoma oil and gas accumulation zone has a complex structure, including numerous pores, zones of increased cavernosity and fracturing intervals. Fracturing plays an important role in fluid filtration, and as a consequence of hydrocarbon accumulation zones. The article is devoted to the specific features of the studying and localization of increased fracturing zones with attraction of geological-geophysical methods in order to predict the possibility of their localization and description.
