  1. Exploration & Production Information Network (EPINET) EPINET System & Standards Dr. Bala Buksh, Chief EPINET Coordinator KDMIPE, ONGC Dehradun - India

  2. The EPINET System Adoption of Standards Association with Energistics Road Ahead AGENDA

  3. Why EPINET • For any Oil Company E&P data is asset, it needs to be preserved for entire life cycle and this life cycle in case of Oil Industry is more than 50 years. • It takes lot of time for data searching. • Data degradation threat is also major concern when time passes. • Requirement of interpretations & re- interpretations with new tools on old and new data sets to reduce risk factor.

  4. EPINET Objective Compliance of industry standards & best practices Single validated E & P data base throughout ONGC EPINET OBJECTIVE Web based reporting and current E&P data flow into EPINET Flow of analytical & interpretation Data to EPINET Quick and quality data access to users

  5. EPINET- Salient Features • Client-Server computing environment • User friendly database application Software • Extensive GUI capabilities • Fast data communication Network • Concurrent data accessibility • Multilevel data security

  6. EPINET Data Classes • Geology • Seismic • Well Log • Reservoir • Laboratory • Lease • Drilling • Production • Physical Assets • Geoscientific Reports, Seismic sections, Log films, Cores, Fluid samples etc

  9. The state-of-the-art technology is available at all sites of ONGC. The system flow functionalities has been implemented. All E&P data available since inception electronically and in hard copy has been loaded into the system. The current data capturing mechanism has been established. Current Status

  10. Gains & Benefits • Common E&P Data Model throughout ONGC. • Time saving in interpretation projects • Improved integrated interpretation • Reduced exploration risk & cost • Faster & focussed decision making • Avoidance of data degradation • Intellectual gains in terms of • data management skills

  11. Geology • As per recommendations of Task force, Stratigraphy nomenclature in WCR is loaded under a single unified scope as ‘Scope-0’ • WCR version be maintained as Scope=0, while the standardized version of 1993 be created as Scope=1, Further, any additional version (s) generated could be maintained as Version-2 and so on. • Defining UWI structure. • Well Symbols. Well Type

  12. All Mnemonics as numbers have been standardized in line with standards prevailing in the Industry A utility has been developed for loading RUSSIAN data which takes care of adding standard UWI, well name, field etc. Task Force has also given guidelines for loading standard log curves in Finder as merged logs i.e. Resistivity logs, Density logs, Neutron Logs, Sonic Logs, SP logs, Caliper logs, GR logs. Well log

  13. Task Force has given recommendations to adopt standards while loading seismic data for onshore and offshore. This includes: Survey Name Line Name SEGY Headers (2D & 3D) EBCDIC Binary Trace Header Seismic

  14. A wide range of Lab data management activity implemented in EPINET System pertaining to Geology, Geochemistry and Reservoir. For example: CHROMOTOGRAPHY_ANALYSIS CUMULATIVE_RECOVERY_STUDY GAS_ANALYSIS DIFFERENTIAL_LIBERATION etc. The customization has been carried out as per work flow requirement in ONGC. Laboratory

  15. Scope has been created in the data model for EOR, CBM and Gravity Magnetic. ONGC initiated drilling activity codes to smoothen the data work flow during drilling. Taking into consideration of the IADC codes, codification has been carried out to avoid ambiguity for similar kind of operations during different stages of drilling life cycle e.g. Rig Movement: during Rig Building, during Work-over & during lateral drilling etc. Other Data

  16. Daily basis data from Common Data Server (CDS) of SCADA at Assets and Forward Bases will be made available from Oracle Database to Excel sheets as per EPINET formats. Excel data will be loaded on daily basis to the Finder (EPINET) database using spread-sheet loaders which will be atomized through PC based gateway interface. Interface with SCADA

  17. Review of EPINET Phase-I achievements and work study for implementation of Phase-II were carried out by POSC/Energistics as consultant. Energistics Director visited Corporate EPINET Data mangement Centre in Jan 2003 and Sep 2004 and interacted with ONGC teams on E&P data management standardization issues. Association with Energistics

  18. Energistics has provided reviews from time to time on EPINET project. ONGC and Energistics have jointly presented papers and participated in various E&P Conferences and Seminars. ONGC-Energistics technical programs organized during SPG-2004, SPG-2006 and during IORS-2004 in India. Association with Energistics contd.

  19. ONGC got opportunity to interact with international oil community by participating in Energistics annual work program during POSC/Energistics conferences. Such as: Board member meetings at Houston & Paris. Participation of teams of executives in various SIG Meetings in Houston, London and Aberdeen. Association with Energisticscontd.

  20. To get the benefits of standardization through SIGs, it is proposed to constitute SIG teams on; Geology SIG, Drilling WITSML SIG, Production PRODML SIG, Data Management SIG. The four SIGs will have the members from different domain executives of ONGC for participation & interaction of SIG activities and its implementation in ONGC. Standardization Initiatives

  21. The work carried out by ONGC should be considered towards standardization with need base modifications. Wide range of customization has been carried out as per multi-disciplinary work flow requirement for various data classes. This needs to be regularized to avail the benefits of implementation of higher versions/upgrades etc. from vendors. Areas to Focus

  22. The standards entities attributes for EOR, Coal Bed Methane (CBM) and Gravity Magnetic scope need to be defined in the data model in line of ONGC. Lead should be taken by Energistics for Implementation of data mining tools to get early return on investment. Areas to Focuscontd.

  23. Thank You
