Summary
Polymers and related oilfield chemicals—encompassing stimulation agents, enhanced oil recovery (EOR) formulations, and drilling/completion fluids—are fundamental to the optimization of sustainable hydrocarbon extraction. Confronted with the declining productivity of mature reservoirs, advanced polymer-based EOR methodologies, such as functional polymer flooding and polymer-surfactant injection, have demonstrated the capacity to increase ultimate recovery factors from baseline averages of 30-40% to exceeding 50%. Concurrently, the deployment of biodegradable polymers mitigates environmental impacts, thereby reconciling operational efficiency with global carbon neutrality objectives.
This Special Issue aims to assemble cutting-edge research detailing the development, characterization, and application of these critical polymeric materials. The scope encompasses novel polymer formulations, rigorous lifecycle assessments, and empirical field applications. We invite interdisciplinary contributions that prioritize performance enhancement, environmental compatibility, and field-scale viability. Submissions are particularly encouraged across the following core domains:
· Stimulation Agents: Biodegradable polymeric diverters, polymer-based suspension agents, and fracturing fluids.
· EOR Polymers & Chemicals: Functional polymer/surfactant flooding systems, polymer gel-based conformance control, and smart profile modification.
· Drilling/Completion Fluids: High-performance polymeric additives for fluid loss control, clay stabilization, and eco-friendly cementing.
· Emerging Technologies: Nanomaterial-polymer composites and hybrid systems for integrated reservoir management.
