Asphaltene Deposition Control by Chemical Inhibitors: Theoretical and Practical Prospects is the most advanced reference focused on chemical dispersants and inhibitors from both an experimental and modeling viewpoint. Adequate knowledge of the effective parameters in each treatment method, interactions, mechanisms and economic viewpoints involved in asphaltene treatment are crucial for future development, recovery forecast, and reserve prediction, hence this reference delivers on all these aspects. Sections cover the environmental impacts of asphaltene deposition, prevention methods, and experimental methods, both static and dynamic, to test the effectiveness of inhibitors on restricting asphaltene deposition.
Rounding out with modeling methods used to simulate asphaltene-inhibitor interactions and a workflow to select suitable inhibitors by technical, economic and environmental considerations, this book will give today’s engineers and researchers the right tool to mitigate formation damage in a sustainably responsible way.
- Focuses on inhibitors, mitigators and the interplay between the asphaltene-inhibitors
- Helps readers learn from experimental models and replicate treatments with screening workflows
- Includes case studies that help readers make sustainable and economically-sound decisions on treatments
