OBJECTIVE
During past five decades ONGC has carried out extensive exploration, drilling and production activities in the Indian sedimentary basins and over the time has acquired enormous volume of geological, geophysical, logging and engineering data. Like other companies ONGC initiated data management activities way back in 1976, by developing well information system on IBM-370. Furthermore, other systems also emerged at different work centres of ONGC to cater to the data management needs. Eventually, in-house database systems were felt inadequate and required to be replaced with commercial industry standard solution. ONGC in late 1990’s decided to implement the recent advancements of the web based E&P information management technology. ONGC conceived Exploration & Production Information Management and Networking (EPINET) project comprising of people, processes, tools, data and a hierarchy of corporate, regional and working project database in a phased manner. The project is intended to establish an organization wide dynamic, “Virtual” database having GIS features and Web capabilities.

11. WITSML IMPLEMENTATION

12. WITSML FOR REAL TIME OPERATION

13. WITSML FOR REAL TIME OPERATIONS
Well-site / platform
ONGC, Paradigm and Halliburton developed a software (2003).
Interact & Insite (2004 onwards)
LWD/MWD objects.
Used for Geo-steering in Mumbai High.
Visualization Center (VRC)

14. PANNA MUKTA TAPTI (PMT)
PROJECT

15. PMT PROJECT
Introductory Meeting held in Kolkata in Jan 2006 during SPG.
Attended by representatives from ONGC, BG & Reliance.
It was decided to go ahead with the Pilot in PMT JV because of its multi-operators environment.

16. DATA OBJECTS Data Objects for Stage-I (Drilling+G&G centric)
Log Object (MWD, LWD, Wireline)
Well / Wellbore object (well header information)
Trajectory object
Mud log object
Stage-II planned as Production centric

17. PMT PROJECT Status: Developed Fields. EOR/IOR Phase
Now changed idea to implement PRODML which was earlier planned in Stage II.
