- Data Management
- National Data Repository (NDR)
Introduction :.
As per the petroleum and natural gas amendment rules 2006, every E&P operator in
India is obliged to provide all data elements pertaining to the entire E&P value
chain to Gov of India. This includes but not limited to geological, geophysical,
petrophysical, geochemical, log, map, production data, tapes, cores, cuttings, other
interpretaion and analytical reports etc.
DGH being the nodal agency of Ministry of Petroleum and natural gas on upstream
E&P affairs, has started receiving E&P data from operators gradually subsequent
to NELP regimes. Further one major role of DGH is to store and disseminate this
precious oil field data of India.
It is widely accepted today that E&P dataset is essentially a national asset. This
is quite true in view of the ever increasing technological advancement in the field
of data processing, data interpretation etc. Even age-old E&P dataset might give
new results in view of new technological infrastructure. That is why safeguarding
national E&P data has become a prime area of focus for DGH recently.
Below is a brief account of different data classes available with DGH.
- Cultural Data
- Geological Data
- Petrophysical Data
- Seismic Data
- Well Data
- Production Data
- Reservoir Data
- Various Unstructured Data (Reports, Documents etc.)

Bulk Seismic Data Management :.
Currently DGH is maintaining a offline digital data library to archive different
seismic data received from the operators. These include both processed and raw data
received in different media like 3590, 3490, 3592, 8 mm Exabyte, LTO etc. The above
cartridge information are categorised and viewable based on an Oracle based web
application modules.
Structured Data Management :.
Currently different application modules are in the process of development/deployment
and testing on Oracle 10g database with .net based web based applications to categorise,
catalogue and compile various structured data and meta dataset sets relating to
cultural, geological, production, reservoir, well header, logging meta data etc.
Unstructured & Physical Data Management :.
DGH is currently having a dedicated data room to store all unstructured and physical
data elements like well completion reports, different study reports, analytical
reports etc. They are scientifically catalogued and maintained by well. In view
of the growing importance of national E&P data and these E&P data being India's
national asset, DGH has envisioned an ambitious plan for setting up of a National
Data Repository for India. The proposed NDR will primarily safeguard national E&P
data asset. Besides this will further streamline all associated procedures,policies
and workflows pertaining to data submission, data cataloguing and data viewing by
respective operators. Additionally this will facilitate a common window for all
concerned quarters pertaining to E&P domain including industries, government agencies,
academia and common people. The project has been thaught on an innovative Build-Operate-Populate
and Lease concept.
Government of India in envisaging on an ambitious project to set up a National Knowledge
Hub (NKH) alternatively called as National Knowledge Centre (NKC) in E&P area in
coming few years. The components of NKH/NKC will be
- National Data Repository
- National Processing Centre
- National Visualization & Application Centre
- National Training Centre
- National E&P Knowledge Portal
At present, DGH as mandated by the Ministry of Petroleum and Natural Gas has taken
initiative to achieve the milestone of setting up of the NDR, the first component
of NKC. Below are the major initiatives taken so far:
- Collaboration with Norwegian Petroleum Directorate (NPD)
- Publication of Expression of Interest to set up NDR on Build, Operate, Lease and
transfer basis on 13th October 2006.
- Publication of enquiry for independent consultant for NDR on 12th September 2007
- Consultant completed preparation of NDR Tender Document on August 2008
- Global tender with two-bid system to Build, Populate and Operate a NDR published
on November 2008
- Cancellation of tender due to poor response on May 2009
- Holding of 9th International Conference on NDR in Vigyan Bhawan on September 2009
- Fresh Global tender with two-bid system to Build, Populate and Operate a NDR published
on November 2009
- Evaluation of bids in progress
DGH is actively seeking to establish it as a turnkey project on Build, Populate
and Operate basis. Below are the data classes that have been proposed to put on
the NDR:
- Seismic Data
- Well & Log Data
- Spatial Data
- Drilling
- Reservoir
- Production
- Geological
- Geochemical
- Gravity & Magnetic
- Reports and Document
Objective/goals of National Data Repository (NDR):.
The main objective is to setup National Data Repository of reliable exploration
and production data for India with provisions for seamless access and on-line data
management. Specific goals are:
- To validate, store, maintain and reproduce high quality and reliable geoscientific
data
- To facilitate efficient data reporting, data exchange, and data trading among existing
players including all geoscientific agencies
- To improve DGH’s ability to monitor and control the E&P activities and reporting
- To encourage new E & P activities by providing high quality and reliable data
- To strengthen overall geoscientific activities in India
- To support an open acreage system for an improved Global E & P Business environment
in India
- To provide quality E & P data for Processing, Interpretation and Visualization Centres
at DGH
The proposed NDR will primarily safeguard national E&P data asset and shall help
and promote exploration and production activities in India. Besides, this will further
streamline all associated procedures, policies and workflows pertaining to data
submission, data cataloguing and data viewing, data retrieval and data trading for
all concerned quarters pertaining to E&P domain including stack holders, industries,
government agencies, academia and research communities.
NDR is expected to store and maintain hydrocarbon exploration & production data
in a safe and reusable manner, in perpetuity. The data shall be preserved in accordance
with generally accepted NDR standards, and made available to entitled users.
Having an NDR for India will enhance prospects of petroleum exploration and facilitate
the Bidding Rounds by improving the availability of quality data. With this action,
India will be joining the league of countries that have an NDR and can compete effectively
in the hydrocarbon exploration and production sector. DGH now envisions a move beyond
the NELP, towards “Open Acreage” approach with OALP.
