    Abstract: The claimed technical decision relates to downhole systems for the production of various fluids—in particular, for the production of fluid from a hydrocarbon-bearing formation with the use of hydraulic fracturing. According to the claimed technical decision, a method is disclosed for determining the parameters of the hydraulic fracture near wellbore zone, wherein a cased well with a cemented casing and perforation clusters within the predefined hydraulic fracturing zone or an open hole well is provided. Then, electromagnetic logging is performed prior to formation hydraulic fracturing. The stage, during which the fracturing fluid not containing proppant is injected into the well, and the stage, during which the fracturing fluid containing electrically non-conductive proppant is injected into the well, are performed. Following this, the stage is performed, during which the fracturing fluid containing electrically conductive proppant is injected into the well.
