Maximizing Oil Recovery and Economic Returns through Strategic Well Spacing in the Mishrif Formation, Southern Iraq

Abstract The Mishrif Formation in Southern Iraq is a major carbonate reservoir with significant hydrocarbon potential. However, its complex geology presents challenges for efficient oil recovery. This study investigates the optimization of oil recovery and economic outcomes by integrating dynamic modeling and well-spacing strategies in the Mishrif Formation. Dynamic reservoir modeling provides a detailed simulation of reservoir behavior, enabling precise decision-making regarding Well placement and production strategies. Optimized Well spacing maximizes reservoir drainage while minimizing interference, enhancing overall recovery rates. Using a selected oil field in Southern Iraq as a case study, this research demonstrates the application of these advanced techniques. The results indicate that integrating dynamic modeling with optimized Well spacing significantly improves oil recovery and economic performance. Key findings include increased hydrocarbon production, reduced operational costs, and improved financial returns. This study contributes to the broader understanding of enhanced oil recovery (EOR) in carbonate reservoirs, offering valuable insights for future EOR projects in similar geological settings. The implications of this research are substantial for the oil industry, particularly in regions with complex reservoirs like the Mishrif Formation. The findings suggest that adopting these advanced techniques can lead to more efficient and economically viable oil recovery operations. Future research should focus on refining these methods and exploring their applicability in other challenging reservoir environments.
