Currently, the problem of reducing the efficiency of reservoir pressure maintenance systems at late stages of field development with highly heterogeneous reservoirs is a serious one for the oil and gas industry. This paper considers the Srednebotuobinskoye oil and gas condensate field (SBNGKM), which is characterized by highly heterogeneous reservoir, water cut in some wells exceeding 95%, and low water injection efficiency. In this paper, waterflooding optimization using the streamline method was applied for the first time for the conditions of one of the largest fields in Yakutia – SBNGKM. The objective of the work was to increase the efficiency of reservoir pressure maintenance by redistributing injection between injection wells using hydrodynamic modeling of streamlines. The research materials included a three-dimensional hydrodynamic model of the Bt formation of the SBNGKM central block in the tNavigator software, historical data on 37 production and 15 injection wells for the period 2010-2021. An algorithm for redistributing injection with an increase in volumes in highly efficient wells by 20-30% and a decrease in low-efficiency wells by 15–40% was implemented. The results showed an increase in average injection efficiency by 41%, a decrease in water cut by 3.2% and an increase in cumulative oil production by 65,414 tons over a 10-year forecast period. Practical significance is confirmed by an increased ultimate oil recovery factor by 1.7% without capital expenditures. The prospects of the study are associated with the development of adaptive algorithms for automatic optimization based on machine learning and the integration of real monitoring systems for filtration parameters. The implementation of the proposed methodology can significantly increase the economic efficiency of developing complex reservoirs at a late stage of operation due to the rational use of the existing well infrastructure and water resources.

Currently, many large fields with a massive gas cap have an acute problem of breakthrough gas from gas caps produced during the development of oil from thin oil rims. One of the possible ways to limit gas production and reduce the gas factor is periodic operation of wells. To accelerate the alignment of the gas cone and return the fund to production during periodic operation, re-injection of degassed oil into a reservoir is used. The paper analyzed the field experience of periodic operation of wells with the injection of degassed oil. In order to perform high-quality comparative calculations of different options, hydrodynamic modeling of periodic operation of wells and re-injection of oil into the reservoir was used based on the digital model of the Srednebotuobinskoye field (SBOGCF). Based on the modeling results, the main patterns were identified. When modeling periodic well operation, the number of shutdowns and shutdown duration were used as variable indicators; when modeling periodic operation with degassed oil injection, the volume of injected degassed oil was added to the variable indicators during modeling. The cumulative oil production was used as a control indicator. The modeling results show that periodic well operation and degassed oil injection lead to an increase in cumulative oil production for all calculation options. At the same time, if we compare the options with periodic operation with the option of periodic operation with oil reinjection into the reservoir, then oil reinjection into the reservoir in volumes of up to 100 m3 does not lead to additional oil production compared to pure periodicity.
