Abstract
In the context of the active development of gas condensate fields with several reservoirs in the Gogrendag-Ekerem Upland (Korpedje, South Gamyshlja), the study of its technologies is an important area of work. The study aims to optimise the technology of simultaneously separating two gas condensate reservoirs by lifting products with one tubing string to increase hydrocarbon production efficiency. The methods used include the analytical method, functional method, statistical method, synthesis method, and others. In the course of the study, an innovative methodology was developed for the dual completion operation (DCO) of two gas condensate reservoirs, which involves lifting products with a single tubing string. The key element is the refinement of the calculations made. A detailed analysis of the equipment used in the Gogrendag-Ekerem area showed that it can also be effectively used in other regional fields, ensuring the proper functioning of each element above the packer level. At the same time, it is necessary to pay attention to the various individual characteristics of the field to achieve a truly effective configuration of this technology. The new technology incorporates optimised pressure, flow, and control parameters for each reservoir, resulting in increased production efficiency and reduced energy costs. A significant reduction in the negative impact on the environment and an increase in the overall sustainability of the production process have been identified. These features make the proposed technology an important contribution to the development of the oil and gas industry, contributing to more efficient and environmentally sustainable hydrocarbon production and highlighting its potential for application in modern field development. The practical significance of the research lies in the creation of a more efficient and sustainable hydrocarbon production technology, which not only helps to optimise production processes and reduce environmental impact but also provides the industry with a valuable tool to improve overall energy efficiency and sustainability in the face of ever-changing energy requirements and challenges
