| 8:00 – 8:45 | Conference Start | |
| 8:45 – 9:30 | 0401 | Automated Pipeline Optimization ( |
| Dale R. Rusnak & E. Philip Ferber - Dominion Transmission | ||
| A demonstration of a static model to minimize compressor fuel usage in Dominion's Gas Transmission system: highlighting measured savings, semi-automated calibration techniques and an "Expert System" employed to attain fuel minimization in transient operations - an approach to transient optimization. | ||
| 9:30 – 10:15 | 0402 | Rich Gas Pipeline Operations During Tail-end Production |
| Dr. Lars Hagesæther and Dr. Ronny Albrechtsen - Statoil Natural Gas Ronny S. Bruvold - Statoil Exploration and Production Willy Postvoll - GASSCO |
||
| The multiphase pipeline from Huldra to Heimdal will represent an increasingly difficult operational challenge during the tail-end production phase as the throughput is reduced gradually. A project was initiated to identify possible options to extend the lifetime of Huldra. The key results from this project, mostly based on multiphase flow analysis using the OLGA2000 simulation tool, will be presented, discussed and compared to operational experience. | ||
| 10:15 – 10:30 | Break | |
| 10:30 – 11:15 | 0403 | The Modeling of Multiphase Systems under Steady-State and Transient Conditions – A Tutorial |
| Dr. Ivor R. Ellul & Geir Saether - Knowledge Reservoir Mack Shippen - Schlumberger |
||
| This tutorial focuses on the complex analysis of multiphase flow in pipelines with emphasis on currently available modeling tools. Case studies will be selected and simulated in “real time” to engage the audience in the modeling process. | ||
| 11:15 – 12:00 | 0404 | Real Time Commercial Supervision at Petrobras |
| Odilia Dauzacker& Marcos Moraes - Petrobras Anthony Collins & William Fernandez - Energy Solutions International |
||
| This presentation discusses the implementation of a real-time model and gas transaction management system for the gas shippers at Petrobras. The integrated system provides Petrobras with the capability to schedule, consolidate, allocate, and provide detailed energy and volume information for invoice generation and provides real-time supervision of the shipper contracts. | ||
| 12:00 – 1:15 | Lunch | |
| 1:15 – 2:00 | 0405 | Series or Parallel Arrangement for a Compressor Station?A Recurring Question that Needs a Convincing Answer |
| Sidney Pereira dos Santos - Petrobras | ||
| This presentation brings back the attention to the compressor station arrangement under a transient analysis as part of a real transportation system with a practical approach. | ||
| 2:00 – 2:45 | 0406 | Better Automatic Tuning of On-Line Models |
| Dr. Jason Modisette - Atmos International | ||
| This presentation reports on a new method of tuning pipeline models that simultaneously considers SCADA and model results from a large time span to find the best physical explanation for SCADA/model discrepancies. This approach allows better error compensation than traditional tuning methods. | ||
| 2:45 – 3:15 | Chairman’s Session | |
| 3:15 – 3:45 | Break | |
| 3:45 – 4:00 | 0407 | Update on PSIG Standards Initiative |
| PSIG Standards Committee | ||
| This paper will give an update on the status of the PSIG standards initiative and a demonstration of the portions of the XPLS which are available for review. | ||
| 4:00 – 4:45 | 0408 | The Physics of Centrifugal Compressor Performance |
| Rainer Kurz - Solar Turbines, Inc. | ||
| This presentation explains the physical background of the working principles and the operational behavior of centrifugal compressors, as well as important subsystems such as seals and surge control. | ||
| 6:00 – 7:30 | Reception |
