Online Modeling of Single and Multiphase Flow Networks

For 29 years, our team of specialists have designed and installed real-time online systems that are designed to monitor production, gathering, export and transportation systems. These systems currently support the operations of 30% of the world’s LNG production, and about 10% of the global natural gas pipeline networks and various important oil developments.

The wealth of functionalities these online systems offer include, but are not limited to, individual well virtual (inferential meeting), production allocation, preventing and monitoring flow assurance issues (e.g., hydrate, wax and asphaltene formation), addressing operational integrity (associated with leak and restriction detection, preventing liquid slugging, managing pigging/scraper operations, composition tracking, and preventing pipeline over-pressurizaiton), and ensuring production nominations are met and achieving economic targets.

This talk will discuss what are the key requirements and lessons learned to provide accurate 24/7 monitoring and surveillance of these vital operations, particularly those when there is only limited access to the server machines on these assets. Typically updates to tuning parameters and model components can only be made on limited basis (circa 3 to 12 months between updates). Topics covered will include robustness of models and measured data filtering, the differences between design and as-build configuration data (pipeline elevation, composition, soil properties etc.) , tuning of models and the design of applications for control room operators vs. engineers.
