Advancing Sustainable CCUS Wells with Fiber-Reinforced Polymer Alternatives

Fiber-reinforced polymer composites (FPCs) are increasingly viewed as cost-effective alternatives to corrosion-resistant alloys (CRAs) for carbon capture, utilization, and storage injection wells, but their long-term performance under carbon dioxide (CO2)–water environments remains inadequately understood. This work identifies the dominant degradation mechanisms of FPCs and proposes a practical qualification method for defining safe operating envelopes across different composite grades. The results show that properly selected FPC systems can achieve durable performance at moderate temperatures, enabling broader deployment of composite tubular technologies.1 Because composite manufacturing requires substantially less energy and generates a lower carbon footprint than CRA production, its adoption can meaningfully support global net-zero emission goals.
