Summary

New digital monitoring and control, HMI solutions, and services to support expansion in Onshore Gas Development Phase III (OGD–III) projectFOXBORO, MASSACHUSETTS, USA – March 27, 2006 – Invensys Process Systems has been selected to provide advanced SCADA (Supervisory Control and Data Acquisition) systems for Abu Dhabi Gas Industries Ltd. (GASCO), who is managing the Habshan gas plant expansion project, OGD-III, on behalf of Abu Dhabi National Oil Company (ADNOC). Located in the Emirate of Abu Dhabi, United Arab Emirates (U.A.E.), the Habshan complex is one of the largest gas processing plants in the world. The expansion is designed to process an additional 1,306 MMSCFD of condensate-rich gas at the Habshan complex.The new systems will be used to monitor and control all gas wells and remote manifold stations associated with the Habshan complex. This includes replacement and expansion of existing SCADA systems with the latest Foxboro SCADA (www.foxboro.com) technology. As part of the SCADA contract awarded by Eastern Bechtel Co. Ltd, the EPC contractor appointed by GASCO for the project, Invensys will provide professional services for project management, engineering, design, development, integration, testing, and on-site support, as well as training services for engineering and operating personnel. This set of professional services brings together the worldwide Invensys SCADA resources, implemented at the Invensys SCADA center in Rome, Italy, in the U.A.E., and on site at the GASCO Habshan complex. The new SCADA project is designed to meet GASCO’s main goals of maximizing the reliability and availability of gas well production and the inherent requirement for frequent cyclic polling of all critical production data. To meet this need, extensive redundancy will be implemented throughout the system, from the intersystem communications and remote terminal units (RTUs), to the UHF radio data transmission system. In addition to optimal system availability, the high reliability of Foxboro SCADA data handling will help GASCO achieve safety and environmental goals for processes within the plant expansion. Invensys is working closely with Bechtel, the OGD III Project EPC contractor. Overall project completion is scheduled for April 2008. The Invensys SCADA architecture will employ a Wonderware (www.wonderware.com) kernel specifically configured for oil and gas applications and utilizing the award winning InTouch software as the foundation for the human machine interface (HMI). Field data and controls will be managed by remote sub-systems based on systems from the Foxboro RTU (Remote Terminal Unit) family. The RTUs will be located at more than 180 sites for existing and new gas production wells, remote manifold stations (RMS) and gas re-injection wells associated with the complex. Optimal redundancy has also been designed into the RTU network. All RTU configurations will have redundant CPUs, and will connect with the control rooms by means of a dedicated, redundant two-channel, high-sensitivity UHF radio data transmission system. This means that each server in the new main control room can poll the field RTUs through any of four alternate paths. Approximately 10,000 I/O points throughout the Habshan complex will be controlled or monitored by the new SCADA system, including 8,000 relating to the production and injection wells and remote manifolds, with the balance relating to the well services emergency shutdown systems and DCS systems. In the new control room, the configuration will employ redundant master SCADA servers with real time database management and a comprehensive InSQL historian database. The servers will be interconnected on a redundant high-speed Ethernet LAN. The new control room will be linked to monitoring and control sites at two other control centers, including one at the nearby Bab plant. HMI workstations will be located in the new main control room and at the remote centers. To meet GASCO requirements for continuous plant operation, the changeover to the new SCADA system will be implemented in parallel with the existing SCADA system during ongoing production operations at the Habshan processing facilities. The OGD-III facilities expansion for Habshan’s main processing areas will include two trains each comprising inlet separation, condensate stabilization, gas treatment and natural gas liquids (NGL) recovery units. The project will also include installation of a new NGL pipeline from Habshan to Ruwais, and a gas re-injection system, as well as various utilities and offsite facilities. Residue gas will be re-injected back into the reservoir for pressure maintenance purposes. The Foxboro SCADA system to be delivered will also be engineered with future GASCO expansion plans at the Habshan complex in mind, with a capacity to accommodate an intended ultimate population of 240 RTU systems.About GASCO, Abu Dhabi Gas Industries Ltd. GASCO, Abu Dhabi Gas Industries Ltd., is the operating company responsible for the processing of natural and associated gas from onshore oil operations in the Emirate of Abu Dhabi, United Arab Emirates (U.A.E.). GASCO was incorporated in 1978 and has grown to become one of the biggest industrial complexes in the U.A.E. It is also one of the largest gas processing companies in the world, with a process capability in excess of four billion standard cubic feet of gas per day (scfd), producing 140,000 barrels of condensate, 4,000 tons of sulphur and 18,000 tons of natural gas liquid (NGL) per day. The gas processing and NGL extraction operations take place at Habshan and three other desert plants. The processed products are then transferred to various downstream plants and to customers through a network of pipelines. Gas delivered into the distribution network is mainly used as fuel for power generation and water desalination throughout the Emirate of Abu Dhabi.
