Since 2008, PermNIPIneft Branch of LUKOIL-Engineering LLC in Perm has been performed a complex of works on scientific-engineering support of hydraulic fracturing at Perm region fields and since 2017 it has been the same at the fields of the Komi Republic and the Nenets autonomous district. Hydraulic fracturing technology is implemented at all oil and gas bearing complexes of the regions. Significant differentiation of geological and physical characteristics of productive formations causes an individual approach at the performance of hydraulic fracturing for each production zone. The main objectives of improving the hydraulic fracturing technological efficiency are the following: increasing of the fracture conductivity, increasing of conformance along the horizontal and in a vertical sense, reducing uncontrolled leakage of breakdown agent, excluding the water-cut growth, reducing the fracture height in the conditions of nearby gas-and water-saturated intervals. The article presents the main problems of hydraulic fracturing for each of the considered oil and gas bearing complexes, describes the main technological solutions. Continuous improvement of hydraulic fracturing method is carried out for maintaining a stable technological efficiency in the conditions of gradual deterioration of geological and physical conditions of wells-candidates. The main areas of work are identified and technology modifications are successfully selected for solving the existing problems of development and the problems of effective hydraulic fracturing implementation.
