The paper presents a method for calculation of closure pressure on hydraulic fractures on injection wells as a parameter determining the beginning of fracture growth. The method is based on formation stress-strain state modeling in an area close to the fractured wellbore. The model for calculation takes into account the evolution of pressure field caused by exploitation. The results of modelling show good agreement with field data and can be used as a method alternative to field measurements methods, that now-a-days are the basic instrument of closure pressure determination. © B.A., 2014 Source

Article is devoted to methodology for determining leak off coefficients on core samples, allowing you to explore filtering fracturing fluids in the rock and adjust designs fracturing in all major industrial simulators of hydraulic fracturing. Considered constant and dynamic models. The relationships between rock permeability and leak off coefficients are determined. Using the techniques presented may improve the efficiency of the operation hydraulic fracturing. Source

This paper concentrates on integrated approach to optimization of development of mature fields and on aspects of development of wedge-shaped reservoirs such as major reservoir BS10 of Mamontovskoe field. Localization of wedge zones has been performed as potential areas of the remaining recoverable reserves by the analysis of well works results inside and outside of wedge zones. Integrated approach to analysis and identification wells in such geological conditions has been developed and described, and direct program of well works for production and injection wells is compiled.

Western Siberian and Volga region oil fields, as a rule, are characterized with low reservoir pressure and exploitation by the method of mechanized extraction, that does not allow to assess the productivity in steady mode of fluid output (extraction) (flow rate), that is easily implemented in gushing wells. That's why geophysical surveys (GS) are performed in overhaul periods, after stopping the well and extraction borehole equipment. In that case, is sufficiently disrupted work mode of well and reservoir, depression and flow rate created with GS does not correspond to the operating mode. Increasing the number of horizontal wells shows the urgency of the problem of assessing the efficiency of the multistage hydraulic fracturing. To eliminate these restrictions can be applied the technology of ESP bypasses (Y-Tool), where the borehole equipment is delivered on the CT below the depth of descent pump in horizontal wellbore interval.
