CCEA approves survey project of Un-appraised Areas of Sedimentary Basins

The Cabinet Committee on Economic Affairs (CCEA) has approved survey project to acquire 48,243 Line Kilometer (LKM) 2D seismic data for appraisal of Indian sedimentary basins where limited data is available.

Sedimentary basin is a low area in the Earth’s crust, of tectonic origin, in which sediments accumulate. It can range from as small as hundreds of meters to large parts of ocean basins.

India has total 26 sedimentary basins covering area of 3.14 Million Sq Km (MSK) spread over onland, shallow water and deep water. 48% of total sedimentary basin area (about 1.502 MSK) does not have adequate geo-scientific data.

Key Facts

The project will be implemented by Oil India Limited (OIL) and Oil and Natural Gas Corporation (ONGC). Under it, survey work will be carried out in 24 States. OIL will conduct survey in North-Eastern States, while ONGC will cover remaining area. The entire project is likely to be completed by 2019-20.

After appraisal of these sedimentary basins, blocks will be offered for further exploration and production activities based on prospectivity of area. It will help in increasing the investments in domestic production of oil and gas and generate direct and indirect employment.


The appraisal of all unappraised areas is considered an important task to launch future Exploration and Production (E&P) activities. Data acquisition will provide initial insight into basins and help in planning future E&P activities. It will be useful in deciding focus areas of exploration activities in country and on basis of this primary data, E&P companies will be able take up further exploration activities in acreages allocated to them.

National Seismic Programme launched in Odisha

The Union Government has launched National Seismic Programme (NSP) to trace hydrocarbon resources like oil and natural gas in Mahanadi basin.

It was launched by Union Minister of State (MoS) for Petroleum and Natural Gas at Taranga village under Soro block in Balasore district of Odisha.


Mahanadi basin has been chosen as the first location for the roll out of this national-level programme. The outcome from the NSP help in better understanding of the sub-surface with petroleum systems across wider geological ages especially in sedimentary basins to explore hydrocarbon reserves in Odisha.

What is National Seismic Programme (NSP)?

  • NSP aims to undertake a fresh appraisal in all sedimentary basins across India in order to have better understanding of the hydrocarbon potential of the country.
  • Under this programme, high-resolution 2D seismic Acquisition, Processing and Interpretation (API) survey will be conducted across India especially in the sedimentary basins.
  • The survey will be conducted by state owned Oil and Natural Gas Corporation (ONGC) and Oil India Limited (OIL). The survey project will be completed by March 2019.
  • ONGC will conduct the survey of around 40,835 Line Kilo Meter (LKM) in onland part of 26 sedimentary basins in 18 states/UTs including Mahanadi basin.
  • While OIL will carry out the survey of 7,408 LKM in the North eastern states of Assam, Manipur, Arunachal Pradesh, Mizoram and Nagaland.
