|From well to board-room, a giant leap for ONGC|
27 March, 2008
Mr. R S Sharma, CMD, ONGC, activated the Phase-I of SCADA project at Mumbai on March 27, 2008. Integrated by one enterprise wide system- SCADA. Supervisory Control and Data Acquisition is an automation tool that will bridge the gaps in the process control realm. The project would bring real time data from well to board room, empowering the decision makers.
247 onshore Production installations, Group Gathering Stations, Central Tank Farms, and Central Processing Facilities. Processing Plants at Uran and Hazira. 11 offshore Process complexes catering to 157 offshore well-head platforms. 65 Onshore and 9 Offshore drilling rigs will now be integrated.
In the first phase of SCADA Go-Live, Neelam & Heera, Bassein & Satellite, Ahmedabad, Ankleshwar, Mehsana, Uran and Trombay were added on-line. Mr. RS Sharma, logged on to the sytem to access production figures and refinery dispatches from the onshore assets. He also interacted with the Asset heads.
ONGC had engaged ABB Limited, for implementation and integration of the project on all the installations of ONGC at a total cost of Rs. 430 crore.
To meet the challenges of real time integrated oilfield operations, ONGC zeroed down on to ABB's state-of-the-art SCADA Vantage for its Production Facilities and National Oilwell Varco's FALCON for the Drilling facilities.
Complimenting the team Mr. RS Sharma, said "data capturing in real time, data storage, backup, trending and analysis, all systems are designed to minimize the distance, time and ambiguity between the well and the boardroom".
Notes to Editor
247 onshore Production installations, Group Gathering Stations, Central Tank Farms, and Central Processing Facilities, Processing Plants at Uran and Hazira,11 offshore Process complexes catering to 157 offshore well-head platforms, 65 onshore and 9 offshore drilling rigs will now be integrated by one enterprise wide system - SCADA (Supervisory Control and Data Acquisition), which is an automation tool that will bridge the gaps in the process control realm.
To meet the challenges of real time integrated oilfield operations, ONGC zeroed down to ABB's state-of-the-art SCADA Vantage for its Production Facilities and National Oilwell Varco's FALCON for the Drilling facilities.
SCADA software packages for data accumulation have been uniquely customized to map ONGC's need. Once implemented, all the installations of ONGC for Production and Drilling facilities will be monitored on 24x7 real-time basis. The Proposed Enterprise wide SCADA system follows the three tier architecture, commensurate with its hierarchical organizational structure.
Tier One is at the Production and Drilling installations where process, well, drilling and plant information in terms of process parameters are gathered. Tier One has independent functionality and shall meet the day-to-day requirement of operating personnel at the installation. Real time - Oil Field Operation Data will be collected by the SCADA system from field instruments. ONGC has decided to induct the state of art Foundation Field Bus based Field Instrumentation systems at all Production installations. This decision would make it a leader with having the largest Foundation Field bus installed base in the Oil industry.
Operation Data from drilling rigs, including mud parameters, rotary parameters, hook load, rate of penetration, depth and pump parameters will be acquired and recorded in the SCADA system. This information will be made available to Drilling Engineers, Chemists and Geologists at drill-site.
Tier Two is at the Asset Headquarters. The Tier I SCADA Systems will be networked with the Tier II Asset SCADA system through SATCOM and microwave links. Real time operation control centers have been planned at this tier to enable the management at the Asset Headquarters to monitor the activities of the production and drilling installations.
They will be able to consolidate and analyze individual installation data, allowing production and drilling manager's instant access to relevant information, close integration with various work centers at the Asset as well as the installation. The data will also be seamlessly integrated to the organization's scientific repository EPINET, and the SAP Based ERP system ICE.
Tier Three is at the ONGC office at Scope Minar, New Delhi, where key parameters will be pooled from all Tier II locations. This centre will enable ONGC to get common unrestricted access to real time information regardless of geographic proximity. Time-stamped SCADA data generated at Tier II locations will be used by EPINET, while Tier III data will be used by ICE-SAP.
In case of failure of one of the redundant systems at Corporate Headquarters, the system automatically switches to the standby database at the same location. In the case of an extreme disaster where both systems are not functioning or destroyed, a data recovery procedure comes into play - the mirror site in 11 High office in Mumbai is activated.
The SCADA-Vantage and FALCON systems have completely removed the issues that arose with the conventional data reporting procedure. Automation and advanced technology has allowed decision makers to base their reasoning on accurate and live data, allowing for more efficient planning, production and analysis. The system facilitates distributed management and contributes towards increased safety of installation and rig personnel. It provides summarized and detailed aggregate information to management and also plugs seamlessly into Third-Party Enterprise Applications, and various analysis tools. Single point measurement through electronic instruments removes the risk of manual intervention and tampering, and an experienced individual can oversee multiple installations simultaneously.
