Experience in developing oil rims at the Novoportovskoye field through the reinjection of associated petroleum gas

Developing oil rims presents a complex engineering challenge that requires careful consideration of various factors. One of the primary difficulties in oil rim development is selecting appropriate well completion methods and reservoir pressure maintenance technologies to ensure effective production of reserves.Drilling multilateral wells in oil rims can help limit the rising gas factor at early operating steps. However, multilateral well architecture can significantly affect development efficiency and remains an area of further studies.While water injection into the reservoir for maintaining reservoir pressure is a wellestablished and widely used technology, gas re-injection into the gas cap of an oil rim is a promising approach with effect requiring further validation through estimates and practical results.This paper discusses the experience of constructing complex injection wells and implementing the gas re-injection of associated petroleum gas at the Novoportovskoye field. The authors describe the approach to the definition of strategy aimed at asset development. Also, the authors present results from the injection of associated petroleum gas, which aimed to maintain reservoir pressure and removal of risks of failure to meet the 95% standard for rational utilization of associated petroleum gas.
