Abstract

This study addresses the challenges of managing asphaltene precipitation in oil well production, aiming to
establish a rapid computational approach for production management based on individual well productivity. The
methodology involves modeling the impact of inhibitors on tubing diameter and incorporating well and reservoir
performance. Validation using real-world data reveals optimal production conditions related to Asphaltene Onset
Pressure (AOP) and Bubble Point Pressure (Pb) in relation to inhibitor location. The study emphasizes the
importance of positioning AOP above the perforation interval for operable conditions and observes the impact of
asphaltene deposition on wellhead pressure. To address increased bottomhole drawdown pressure, a production
rate regulatory program is developed. The research offers a novel computational approach for managing
asphaltene precipitation, grounded in real-world data, and provides insights into optimizing production rates
while ensuring flow assurance in oil well operations. Additionally, strategic recommendations for field development
are proposed, including acid/hydraulic fracturing and deviated horizontal/bilateral wells drilling to
mitigate bottomhole drawdown pressure.
