Description

Abstract:

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.

Speaker: Dr. Dale Erickson

Dr. Erickson serves as the Technical Authority and Technology Development Lead for Intelligent Operations at Wood. At Wood he has pioneered the development of real-time, transient, multiphase flow simulators, leak detection systems, and control/optimization software for platforms/pipelines and wrote most of the core code for the multiphase pipeline simulator. In addition, he has been involved in numerous technical studies involving transient multiphase flow and dynamic process modelling. Since 1996, has had a significant role in over 100 projects, by providing functional design, detailed design approval, trouble shooting, tuning, quality review and testing and technical supervision. He worked in the area of flow assurance by writing the first version of the Colorado School of Mines Hydrate program in 1983; then developed high accuracy equations of state in conjunction with NIST in Boulder, CO while getting his PhD from Rice University. He co-developed a thermal soil model enhancement and a bundle model enhancement for OLGA, and developed the first commercial model for paraffin formation. He has recently developed a model of Oil Shale Well Operation including a simplified Reservoir Model. He also worked on a model of the largest CO2 Storage Network.
