Nazarbayev University School of Mining and Geosciencehttp://nur.nu.edu.kz/handle/123456789/8045Enhancing oil recovery in mature oil fields poses a considerable challenge within the oil and gas sector. Despite the prevalent application of waterflooding techniques, significant amount of oil often remains unrecovered. This study focuses on enhancing oil recovery in the Uzen field, through the implementation of polymer flooding alongside hot water flooding and hot polymer flooding methods. Numerical simulations are employed to evaluate the influence of operational parameters on the efficacy of polymer flooding. Key parameters under scrutiny include the polymer injection rate, duration of flooding, and polymer concentration. The main objective of this investigation is to devise an optimal set of operational parameters specific to the Uzen field, thereby maximizing the effectiveness of polymer flooding. The outcomes derived from the numerical simulations reveal that the most favorable polymer injection rate is 140 m3/d, with an optimal polymer flood duration of 20 years, and an optimal polymer concentration of 2500 ppm. Characterized by a high water cut, the Uzen field represents a prime candidate for the implementation of polymer flooding as a tertiary recovery strategy. By conducting comprehensive experimental and simulation studies, different operational parameters were designed and evaluated. Practical recommendations were provided to enhance oil recovery within the Uzen field, based on an integrated research approach.enAttribution 3.0 United StatesType of access: Open accessMaster's thesis
