Fiberglass-Lined Tubing Helps Prevent Asphaltene Deposition in Oil Wells
This paper describes strategies for mitigating asphaltene deposition using fiberglass-lined production tubing and the successful trials thereof.
Asphaltene deposition in production tubing represents a major flow-assurance challenge. Common strategies to mitigate asphaltene deposition downhole include mechanical or solvent cleanouts and chemical inhibition. These are associated with production deferment, high job costs, safety and environmental risks, and operational issues. An operator has addressed this challenge using production tubing lined with glass-fiber-reinforced epoxy (GRE). This technology was implemented in two trial wells.
