A multi-perforated horizontal well is one of the most effective methods to improve sweep efficiency in hydrocarbon recovery. However, this approach often faces challenges such as influx imbalance and increasing water-oil ratio (WOR), which can significantly reduce production efficiency. To mitigate these issues, inflow control device (ICD) are installed at each perforation interval to regulate fluid entry and ensure uniform inflow along the wellbore. In this study, a conceptual sandstone reservoir model was used to perform a sensitivity analysis aimed at identifying the most influential parameters in ICD installation performance. The results, presented in a Pareto chart, indicate that porosity (followed closely by permeability) and grid thickness are the most sensitive parameters affecting oil production. Building upon this, an advanced sensitivity analysis was conducted by combining these key reservoir properties with various ICD valve opening percentages. This process led to the development of a fluid flow dynamic model equation, which serves as a valuable tool for optimization. The objective is to determine the optimum reservoir intervals and ICD valve openings that maximize cumulative oil production while minimizing WOR, ultimately enhancing the effectiveness of ICD implementation in horizontal wells.
