Oil Discovery Overview

  • This discovery of oil in the Krishna Godavari Basin block along the Bay of Bengal was announced by the Cairn Oil & Gas, a subsidiary of Vedanta Limited.

  • The zone from 3,403 metres to 3,431 metres was tested through conventional well testing (drill stem test) and flowed oil to the surface

  • The Cairn India had won the KG-OSN 2009/3 block in June 2010 during the edition of the New Exploration Licensing Policy (NELP).

  • It contributed about 25 % to the country’s domestic crude oil production in 2017 - 18.

  • KG-OSN-2009/3 offshore block in the Bay of Bengal was originally spread over in an area of about 1,988 sq. km which was later reduced to 1,298 sq. km. This reduction was due to exclusion of area within firing range.

  • It is located in the shallow waters of the Indian Ocean along the East coast of India, approx. 1.5 km from the Indian coastline.

Earlier Gas Reserve Discovery & Latest Developments

  • Along the same Krishna Godvari Basin, the site Dhirubhai-6 (D6) exists where Reliance Industries discovered the biggest gas reserves in India.

  • India’s Reliance Industries Ltd and partner BP said recently that they would start developing a third gas field off India’s east coast.

  • As per Reliance 3 projects, developing 3 trillion cubic feet (tcf) of discovered gas, would cost 350 billion rupees ( $5 billion) to develop and could produce about 30 million standard cubic metres of gas per day (mscmd) phased over 2020 - 2022. This will definitely help in increasing demand for clean fuel in the country and therefore would dependency on the imported gas.

  • India’s biggest oil and gas explorer, Oil and Natural Gas Corporation Ltd, is also developing reserves off India’s east coast. The production is expected to be around 2022 - 2023; the company will produce 15 mscmd of gas.
