The public sector Indian explorer Oil and Natural Gas Corporation Limited also popularly known as ONGC has struck a gas reserve in the form of hydrates off the Andhra coast that could turn out to be four times larger in terms of yield than Reliance Industries Ltd's discovery of 2002, India's biggest so far.
The discovery was made in August last year by the second exploratory expedition under the government's gas hydrate programme in collaboration with scientists from US and Japan, which have separately inked research Memorandum of Understandings (MoUs) with India.
According to the Directorate General of Hydrocarbons, the oil ministry's technical arm co-ordinating the gas hydrates programme, the discoveries have been made in Blocks 982, D3, D6 and D9 in the Krishna-Godavari basin, off the Andhra coast. These blocks are around 30 Kms south-west of Reliance industries Ltd's natural gas block KG-D6.
Krishna-Godavari (KG) Basin is spread across 50,000 sq km in the Krishna River and Godavari river basins near the coast of Andhra Pradesh. The site is primarily known for the Dhirubhai-6 (D6) block, where Reliance Industries discovered the biggest natural gas reserves in India in 2002.
