Hydraulic fracturing is one of the most effective hydrogeological technologies used in Russia. Multi-stage hydraulic fracturing technology is considered particularly promising. This article discusses the hydrogeological features of the application of this technology. At the beginning, the author provides General information about the historical aspect of hydraulic fracturing. The paper also pro- vides a number of recommendations that are necessary when using hydrogeological technologies. The necessary stages of hydraulic fracturing organization that are applicable to the majority of exploration wells are justified. The article substantiates the multi-stage use of the technology and traces the geological connection with horizontal drilling. Hydrogeological features of promising technologies for multi-stage hydraulic fracturing are presented, and possible advantages are justified depending on the selected technological scheme.

Key words: hydrogeology, hydraulic fracturing, multistage, reservoir, oil, liner, horizontal wells
