Technology Focus: Flow Assurance (November 2025)

_ Recent technical developments in flow assurance can be summarized as preventive, artificial-intelligence- (AI) assisted, and ecofriendly management (i.e., low-carbon operations). Current research trends emphasize the integrated analysis of experimental data and advanced modeling, AI-driven real-time surveillance systems, and flow assurance in CO2 transport pipelines, with growing interest in engineering analytics of carbon capture, use, and storage. Several field applications exemplify how preventive, ecofriendly, and AI-assisted innovations are advancing practices. Paper SPE 220746 demonstrates that integrated hydraulic modeling and operational analytics could predict paraffin deposition and optimize pigging operations, reducing wax-related production losses. Paper SPE 222678 shows that the field implementation of the New Approach of Design Against Hydrates (NADAH) paradigm allowed controlled excursions into hydrate regions, reducing costs and emissions. Finally, paper SPE 222206 presents a hybrid AI/physics workflow that enabled real-time hydrate detection and response. Flow assurance in petroleum engineering depends on a reliable analysis of inflow and outflow. The complexity of multiphase flow requires extensive experiments and field verification, resulting in the acquisition of large amounts of data. Beyond data-driven predictive models, physics-informed models, combining scale-dependent data and physical/chemical theory, are seen as a major attempt in multiphase pipe flow. The potential of large language models and reinforcement learning remains challenging because they rely on scarce high-quality field data and strict alignment with multiphase flow physics. The advancement of flow-assurance technology can be characterized as a transition from reactive to proactive, from laboratory-scale examination to field applicability, and from data-driven to big data and physics integration.
