This study investigates hydraulic fracturing optimization in low-quality sandstone formations, focusing on Field X. Using TNavigator software and a sensitivity approach, the research analyzes the sensitivity of well performance to five key fracture parameters: width, half-length, height, number of stages, and angle. Sensitivity analyses reveal that the number of fracture stages and fracture half-length have the most significant impact on well productivity, while fracture width shows moderate sensitivity with diminishing returns. Fracture height demonstrates a lower but positive impact, and fracture angle exhibits optimal performance at 90 degrees relative to the wellbore. The study focusing on optimalization of Fracture Conductivity Dimensionless (FCD) with optimum values, with maximization of stimulated reservoir volume. An optimized design featuring three fracture stages, a 500 ft half-length, and 0.2-inch width resulted in an 760% increase in oil flow rate and 173% increase in cumulative production compared to the non-fractured scenario. This research underscores the importance of integrated fracture design that considers parameter interdependencies and balances theoretical optimization with practical constraints. It provides valuable insights into fracture design optimization for low-permeability formations, offering a methodological framework applicable to similar geological settings. The findings contribute significantly to the field of reservoir stimulation, particularly for enhancing productivity in challenging low-quality sandstone reservoirs.
