The study presents an overview of the formation hydraulic fracturing application in carbonate deposits of fields of the Republic of Komi and Nenets Autonomous Okrug. The formation hydraulic fracturing technology has become widely used in carbonate reservoirs since 2012, with over three hundred well jobs performed. A significant share of residual recoverable reserves in carbonate deposits needs to be withdrawn; production rates need to be increased, inter alia, by way of the formation hydraulic fracturing. In the conditions of gradual deterioration of porosity and permeability of candidate wells, maintaining a steady level of technological effectiveness of hydraulic fracturing is ensured by implementing new technologies and optimizing standard processes. The hydraulic fracturing implementation issues are inextricably connected to the main issues of oilfield developments and specific structural features of carbonate reservoirs. Taking into account the specific structural features of carbonate reservoirs and existing development issues, the main objectives of the formation hydraulic fracturing have been determined: fracture conductivity increase; horizontal and vertical sweep increase; reduction of uncontrolled leakage of fracturing fluid; reduction of fracture height in conditions of adjacent water- and gas-saturated interbeds. Presently, a number of technologies has been successfully adapted and is used at the Republic of Komi and Nenets Autonomous Okrug sites. Due to the implementation of the integral approach to selection of the hydraulic fracturing technology modifications, taking into account the existing oilfield development issues and structural peculiarities of carbonate reservoirs, the reliable effectiveness of the method has been ensured in the conditions of deteriorating candidate wells; the technology application range has been extended. The study suggests expanding the range of the existing laboratory analyses to include such aspects as determination of stress intensity factor – fracture resistance and Biot’s poroelastic parameter, study of leakage rate dynamics in regard to various fracturing fluids, depending on the reservoir properties of core samples at given gradients, determination of dependence of proppants dynamic transfer on rheological properties of fracturing fluids and their filtration rates for various degrees of fracture model opening.

Developing democracy institutions and citizen participation in state affairs, the world community focuses on postcolonial studies, which allow us to identify new perspectives, set new priorities in various areas, in law and public administration among others. In Arctic countries, postcolonial discourse has an impact on the methodology of research related to indigenous issues, and this makes possible to understand specific picture of the world and ideas about what is happening in the world. Moreover, the traditions of Russian state and governance are specific and interaction between indigenous peoples and public authorities should be studied with a special research methodology which would reflect the peculiarities of domestic public law and aimed at solving legal issue and enrich public policy. The objective of the paper is to present a new integrated methodology that includes a system of philosophical, anthropological, socio-psychological methods, as well as methods of comparative analysis and scenario development methods to involve peripheral communities into decision-making process of planning the socio-economic development in one of Russia’s Arctic regions — the Yamal-Nenets Autonomous District and to justify and further legislatively consolidate the optimal forms of interaction between public authorities and indigenous communities of the North. In 2020, the Arctic Research Center conducted a sociological survey in the Shuryshkararea of the Yamal-Nenets Autonomous District, which seems to limit existing approaches to identifying public opinion about prospects for developing villages and organizing life of their residents. Our proposed methodology for taking into account the views of indigenous peoples can help to overcome the identified limitations.

Анализ статистики уловов Шурышкарского района показал, что в 2015-2020 гг. промысловое значение имели 12 видов рыб, обеспечивая уловы от 8,6 до 10,1 тыс. тонн. Наибольший вклад в уловы по району вносили щука (47 %) и язь (27 %), доля сиговых в этот период снизилась с 22 до 11 %. Доля района в освоении биоресурсов ЯНАО возросла с 13 до 23 %, вклад в общие уловы щуки, леща, язя, окуня и карася в отдельные годы превышал 30 %. The analysis of catch statistics of the Shuryshkarsky district showed that in 2015-2020, 12 fish species were of commercial importance, providing catches from 8.6 to 10.1 thousand tons. The largest contribution to catches in the region was made by pike (47 %) and ide (27 %), the share of whitefish in this period decreased from 22 to 11 %. The share of the district in the development of biological resources of the Yamalo-Nenets Autonomous District increased from 13 to 23 %, the contribution to the total catches of pike, bream, ide, perch and crucian in some years exceeded 30 %.
