The authors of the articleconsider the experience of hydraulic fracturing (HF) application in the North Caucasus fields. HF has become nowadays one of the main methods for increasing oil and gas production from hard-to-recover reserves. In conditions of traditional hydrocarbon sources depletion, efficient methods of extracting resources from less permeable formations are becoming especially important. Some technologies applied for combating proppant flowback and its types used during hydraulic fracturing operations, the main complications that can arise in the course of these operations and the conditions that a target object should meet to be considered for HF are described. The necessity of detailed studying candidate wells for the tightness of the EC, water cut, presence of a reservoir pressure maintenance system or an active aquifer, possible complications as well as develop an individual design project for a formation hydraulic fracturing is shown.
