This study focuses on the impact of clogging on Electric Submersible Pump (ESP) performance in waxy oil production at Well Y, located in Field X within the Northwest Java Basin. The well is characterized by a deviated trajectory and is driven by a solution gas drive mechanism, with ESP selected as the artificial lift method. During operation, ESP performance is affected by clogging caused by wax deposition, resulting in decreased production efficiency. This study evaluates the effects of varying ESP motor speeds on production flow rate, flow regime behavior, and phase distribution using production modeling and analysis. The study also analyzes the influence of well trajectory on flow regime transitions throughout the tubing. The results indicate that increasing motor speed can reduce the impact of clogging by maintaining higher production rates. However, it may also lead to greater gas separation and increased flow instability. Furthermore, the analysis demonstrates the importance of integrating flow regime evaluation during the early design stage of ESP systems to minimize operational challenges such as slug flow. These findings provide valuable insights into optimizing ESP system design and operational strategies, especially under complex flow conditions.
