Key words: hydraulic fracturing, object, data systematization, Pareto distribution, criteria, method.
Nowadays Russian companies carry out lots of hydraulic fracturing operations which brings great domestic experience of the technology application [1-10].
For example, PJSC “Tatneft” named after V.D. Shashin started independent application of the fracturing technology since 1996 and by the January 2018 more than 1700 operations were performed at different development objects. 20-year experience of oil production from fractured wells reveals not only the benefits of the fracturing technology, but also its disadvantages such as insufficient efficiency and high cost despite careful selection of the wells according to technology criteria. Nevertheless, there is some uncertainty in the selection of candidate wells, which guaranteed good technological effect prediction. Quiet big hydraulic fracturing field statistics brings possibility to perform deep analysis of existing failures and to set criteria of effective fracturing application in the Devonian sediments of the Romashkinskoye oilfield.
