the first time in May, 2001. So far, Government has awarded 30 CBM blocks under four rounds of bidding to National, Private & Joint Venture Companies. In addition, 2 CBM blocks were awarded on nomination basis and one block through Foreign Investment Promotion Board (FIPB) route. These CBM blocks are in the States of Andhra Pradesh, Assam, Chhattisgarh, Gujarat, Jharkhand, Madhya Pradesh Maharashtra, Odisha, Rajasthan, Tamil Nadu and West Bengal. CBM in-place reserves of about 280.3 BCM (9.9 TCF) have been established by different operators as on 1st April, 2018. State-wise and block-wise CBM reserves position is given below:

Shale Gas/Oil Resources

It is estimated that a number of sedimentary basins (Gangetic plain, Gujarat, Rajasthan, Andhra Pradesh and other coastal areas) in India, including the hydrocarbon bearing ones – Cambay, Assam-Arakan and Damodar estimates of shale gas and oil are prospective from shale oil and gas point of view in the Indian sedimentary basins carried out by some agencies are as under:

i. ONGC in August, 2013 has estimated Shale Gas resources of 187.5 TCF for 5 basins namely Cambay, Krishna Godavari, Cauvery, Ganga and Assam

ii. Central Mine Planning and Design Institute (CMPDI): in July, 2013 has estimated Shale Gas resources of 45.8 TCF for one basin, namely Gondwana.

 

iii. United States Geological Survey (USGS) in January, 2011 estimated Technical Recoverable Shale Gas of 6.1 TCF in three basins namely Cambay, KG & Cauvery.

 

Gas hydrates

Gas Hydrates can be an unconventional future energy source world over. World over the production of gas from gas hydrates are at R&D stage. USA, Japan, Russia, China, Germany and Korea are deeply involved in developing a technology to exploit these proved Gas hydrates reserves. In India, Gas hydrate research and exploratory activities are being steered by the Ministry of Petroleum & Natural Gas under National Gas Hydrate Program (NGHP). The presence of Gas Hydrate is established in Krishna Godavari, Mahanadi, Gulf of Mannar and Andaman Basin.
