Exploration of Shale Gas

The Minister of State (I/C) for Petroleum & Natural Gas Shri Dharmendra Pradhan informed the Rajya Sabha in a written reply today that based on the geo-scientific data collected during the exploration of conventional oil and gas, assessments have been made regarding the likely potential of shale gas resources in the Indian sedimentary basins. Various agencies have estimated the shale gas resource potential in selected sedimentary basins/ sub-basins as indicated below:

I. M/s Schlumberger : 300 to 2100 Trillion Cubic Feet (TCF) of shale gas resource for the country (as available in public domain)

II. Energy Information Administration (EIA), USA in 2013: 584 TCF of shale gas and 87 billion Barrels of shale oil in 4 basins (Cambay Onland, Damodar, Krishna Godavari Onland& Cauvery Onland)

III. ONGC: 187.5 TCF of shale gas in 5 basins (Cambay Onland, Ganga Valley, Assam & Assam Arakan , Krishna Godavari Onland & Cauvery Onland)

IV. Central Mine Planning and Design Institute (CMPDI): 45 TCF of shale gas in 6 sub basins ( Jharia¸ Bokaro, North Karanpura, South Karanpura, Raniganj & Sohagpur)

V. United States Geological Survey (USGS) has also estimated technically recoverable shale gas resources of 6.1 TCF in 3 basins (Cambay Onland, Krishna Godavari Onland & Cauvery Onland). Further, USGS has indicated that these basins have also potential for shale oil.

Government has announced “Policy Guidelines for Exploration and Exploitation of Shale Gas and oil by National Oil Companies under Nomination regime” on 14th October, 2013 allowing ONGC to carry out Shale Gas exploration & exploitation in 50 blocks and Oil India Limited in 05 blocks in the first phase.

There is no agreement with other countries particularly with regard to exploiting of shale gas reservoirs. However a Memorandum of Understanding (MOU) was signed between Department of State (DOS), United States of America and Ministry of Petroleum & Natural Gas on 6th November 2010 for “Exchange of knowledge and expertise in the areas concerning Shale Gas resource characterization and assessment in India’’
