Application of Drag Reducer Agents on Multiphase Production Fluids

Abstract This paper presents three field cases that aim to demonstrate the efficacy of modelling in predicting potential gains in pressure drop reduction and identifying process issues associated with the injection of Drag Reducing Agents (DRAs). Simulations demonstrate the performance of DRAs and their impact on flow dynamics in multiphase flow systems were evaluated. The modelling approach allows anticipating pressure drop reduction and provides valuable insights into potential process challenges that may arise during DRA injection. Simulations results reveal promising opportunities for substantial gains. The simulations demonstrate significant potential for reducing pressure drop in complex fields with high water cut rates, among other challenges, thereby enhancing operational efficiency through the implementation of DRAs. Additionally, the modelling approach facilitates the identification of potential process issues. In conclusion, this study exemplifies how modelling can accurately predict gains in pressure drop reduction and effectively identify process issues associated with DRA injection. The results highlight the potential for achieving gains in multiphase flow fields that have not yet been extensively studied, providing valuable insights for the application and optimization of DRAs in multiphase systems.
