Development of Effective Production Strategies for Gas Condensate Fields based on Analysis of Operating Conditions

This study, conducted at the Altyguyi field in Southwestern Turkmenistan, aimed to study the characteristics of oil reservoirs to determine the critical parameters affecting production potential, with the subsequent possibility of optimising extraction processes. The research employed a comprehensive approach, including collecting and processing raw condensate, degassing, and removing butane in the laboratory. Critical components of gas condensate systems were calculated, and well and reservoir characteristics were assessed using the steady-state sampling method. Hydrodynamic studies provided a systematic analysis of the data. As a result of the work carried out in the field, data were obtained that are crucial for understanding the features and characteristics of the oil reservoirs. Key findings revealed that the condensate content in reservoir gas varied across different wells, with values of 69.5 g/m³ for well No. 2 (III), 95.2 g/m³ for well No. 1 (II), and 96.5 g/m³ for well No. 5 (I). Predicted condensate content was 80.5 g/m³ for layer NK7d and 95.2 g/m³ for layer NK8. The oil in this field has a specific gravity of 0.91 g/cm³ and a high paraffin content, negatively impacting well productivity. Expected condensate yields for layers NK7g and NK8 were 95 cm³/t and 118 cm³/t, respectively. The results highlight the importance of systematic studies, including lithology, geology, and production parameters, to enhance field assessment and optimise long-term extraction efficiency.
