This study investigates the underperformance of the XY area in the Z field, which uses steam flooding as the primary method for enhanced oil recovery (EOR). Despite its effectiveness, the XY area has experienced a significant production shortfall of approximately 30% compared to the target. The study utilizes a comprehensive method, including system efficiency assessment and statistical examination, to identify potential relevant factors. Using analog methods and analyzing production data, the study classifies well regions, evaluates steam flood cycle maturity, and identifies areas for well-intervention. The analysis reveals areas for improvement, including optimizing steam injection strategies, and addressing inefficient steam injection and inadequate reservoir conditions. Based on these findings, the study proposes specific recommendations to enhance steam flooding operations in the XY area. These recommendations include increasing injection rates for immature wells, replacing and relocating pumps, and implementing cyclic steam stimulation (CSS) or other stimulation methods. Implementing these strategies is expected to significantly improve production within the XY area, surpassing current levels. This study aims to optimize steam flooding operations and enhance oil recovery in the XY area by addressing the identified factors contributing to underperformance and implementing targeted interventions. Further research and implementation are necessary to evaluate the feasibility and effectiveness of these recommendations in real-world field operations.
