Chemical Inhibitors for Asphaltene Control in the Oil Industry: A Comprehensive Review of Laboratory Experimental Techniques and Performance Evaluation

Abstract

Chemical inhibitors are essential in addressing asphaltene-related challenges in the petroleum industry. This study evaluates their performance using laboratory experimental techniques and identifies suitable methods for specific functions like inhibition, dispersion, and deposition. Through a systematic literature review, this research analyzes existing laboratory techniques for assessing the effectiveness of chemical additives in managing asphaltene precipitation and deposition. The findings highlight the significance of chemical inhibitors in preventing production losses due to deposit blockages in fields. The study also examines the governing factors that impact their performance, such as additive dosage level, operating conditions, and operating medium. This research provides a comprehensive evaluation of laboratory experimental techniques, enhancing the understanding of chemical inhibitors’ mechanisms. It offers valuable insights for operating companies and service providers to select appropriate techniques for screening and selecting chemical inhibitors. The asphaltene control process through effective chemical treatment by the petroleum industry can improve operational efficiency and ensure sustainable hydrocarbon recovery from oil fields.
