The study considers three production zones of Yuzhno-Yagunskoye field. The study analyzes one method of oil intensification from the formation, namely Hydraulic Fracture Treatment (HFT), and provides the results of its influence on development indicators within three zones of Yuzhno-Yagunskoye field. A series of hydraulic fracturing operations was carried out in the period from 1995 to 2017. The methods for analyzing the bottomhole zone of the formation were used to process field data. However, it should be noted that in comparison with previous periods of hydraulic fracturing technology, the effect is reduced, which implies further modification of the used hydraulic fracturing technology. The purpose of this study is to evaluate the process efficiency of hydraulic fracturing at Yuzhno-Yagunskoye field. The above results were used during hydraulic fracturing at Yuzhno-Yagunskoye field.
