Gas hydrates in India
Q. In which of the following places in India are gas hydrates found?
1) KG Basin.
2) Mahanadi Basin
3) Seas off the Andaman Islands- Published on 10 Jun 16a. 1, 2
b. 3
c. 1, 3
d. All of the above
ANSWER: All of the above
- They exist in shallow sediments of outer continental margins.
- Gas hydrates with their abundant resource potential is emerging as a potential fuel resource.
- The preliminary assessment of geological condition and limited available seismic data suggests high possibility of occurrence of large quantity of gas hydrates within the EEZ of India.
- India has long been known to have massive deposits of methane hydrate. These are tentatively estimated at 1,890 trillion cu. m.
- An Indo-US scientific joint venture in 2006 explored four areas: the Kerala-Konkan basin, the Krishna-Godavari basin, the Mahanadi basin and the seas off the Andaman Islands.
- The deposits in the Krishna Godavari basin turned out to be among the richest and biggest in the world. The Andamans yielded the thickest-ever deposits 600 metres below the seabed in volcanic ash sediments. Hydrates were also found in the Mahanadi basin.
- With an estimated amount of trillions of cubic metres of methane gas available in the Gas Hydrate deposits in the Indian waters, Gas Hydrates can be the future source of energy for India.
