The unique Arlanskoye oilfield has been successfully developed for 60 years. Since 2010, there has been a growing trend in oil production. Due to the use of high-performance technologies, such as horizontal drilling with multi-stage hydraulic fracturing, proppant and acid fracturing, optimization of reservoir pressure maintenance system, oil production was increased by 17%. Main object development – terrigenous low carbonic thick series is in the final stages of development, at the same time second largest recoverable reserves the Kashirskian-Podolskian object is actively being developed. Actual tasks for further development of the field are localization of current recoverable oil reserves terrigenous low carbonic thick series and the Kashirskian-Podolskian object development system organization.
For the localization of current oil reserves, a geological field analysis with sector geological and hydrodynamic modeling was used. For both objects, taking into account the peculiarities of their geological structure, fluid properties and the current state of development, a detailed development strategy has been developed, which provides systematic application of advanced development methods (horizontal drilling with multi-stage hydraulic fracturing, proppant and acid fracturing), use of differentiated influence system and measures to regulate the development process in the production and injection wells. The implementation of the strategy will increase the oil production field, create an effective development system of Kashirskian-Podolskian object, reduce the amount of produced water at the main object development and improve the production efficiency of the object's reserves.
