Abstract
Abstract Gas coning is a frequent issue in naturally fractured carbonate reservoirs with a gas cap and an oil rim, leading to decreased oil production and early well abandonment. This paper proposes a production optimization approach for wells experiencing gas breakthrough in such reservoirs to improve ultimate oil recovery. The authors developed a numerical model that incorporates the effects of gas coning and breakthrough on a well productivity in the Karachaganak field. Using this model, authors optimizes production rates to maximize oil recovery while adhering to gas production constraints. The research is focused to demonstrate that the most effective production strategy for a well is to operate intermittently. Additionally, the frequency of a well's uptime and downtime will progressively decrease over time as the fractured zone of a reservoir is depleted. The suggested production optimization approach can enhance oil recovery in naturally fractured tight carbonate reservoirs while reducing the impact of gas coning and gas breakthrough. The outcomes of this study can guide field development plans and optimize production strategies for comparable tight fractured carbonate reservoirs.
