How SAFA Replaces Erroneous EHD Assumptions to Unlock Superior Frac Stage Performance

Controlling flow velocity across perforation clusters is a reliable engineering lever for improving the stage-level Uniformity Index (UI).  

• It acts as a critical bridge connecting perforation geometry, treating rate, and near-wellbore friction.  
• Operating within an optimal flow velocity window provides sufficient perforation friction to balance flow distribution without creating excessive treatment pressure.  
• Data across multiple basins indicates that UI and stimulation efficiency peak within a specific and repeatable flow velocity range.  
• Ultimately, designing stages around flow velocity provides a repeatable, physics-grounded method to normalize different perforation designs and enhance overall cluster performance.
