The study is significant as there are currently numerous oil rim deposits and gas cap layers all over the world with high gas content. These deposits hold a considerable portion of reserves. Utilizing simplistic methods like relying on a rigid water pressure regime for developing those deposits can be extremely challenging. The sharp decrease in reservoir pressure makes it impossible to restore it through these mechanisms, making exploring alternative approaches crucial. Therefore, alternative methods must be considered to access hard-to-recover hydrocarbon reserves for development. For areas with a significant decline in reservoir pressure, water-gas stimulation combined with associated petroleum gas will be investigated and proposed. The article presents a powerful new technique that combines water-gas stimulation with associated petroleum gas, enabling the effective influence of deposits with high gas content. Compressing gas and mixing it with liquid to maintain reservoir pressure eliminates the need for utilizing associated petroleum gas in technological processes. An increase in production of 10%-20% can be achieved using this process, resulting in oil rims that are more economically viable for development. This approach is a gamechanger for the industry and represents a significant step forward in producing more efficient and cost-effective gas extraction methods. Additionally, a software-based approach for utilizing water-gas stimulation has been examined, showing great potential for improving the process.
