The field has been developed from the very beginning as one development object. The total height of the deposits in some places reaches 400 m; accordingly, since the start of development, all productive formations were perforated through without segregation. Field trial carried out on a well with perforation with a total thickness of 182 m revealed 4 productive formations. In order to open all productive layers with fractures and involve them in the development, it was decided to use a 4 stage layout with a hydraulic fracturing sleeve system with a repeated opening / closing cycle. As a result, after multi-stage hydraulic fracturing using this technology, a 4-fold increase in oil production was obtained. In the future, it is planned to apply this method to other candidate wells.</p>multistage hydraulic fracturingpermeabilityfractureconductivityskin factoroil contentUpper Permian depositsмногостадийный гидравлический разрыв пластапроницаемостьтрещинапроводимостьскин-факторнефтеносностьверхнепермские отложения1.Pongratz R., Stanojcic M., Martysevich V.
