The MoU was signed by Subir Raha, chief executive officer, ONGC and Alexei Miller, chairman, Gazprom in Moscow on Monday in the presence of Minister for Petroleum and Natural Gas, Mani Shankar Aiyar, according to the Gazprom.
It provides for assessment of prospects for collaboration in joint oil and gas projects in India, Russia and third countries and deliveries of the joint production in India and third countries.
A joint working group has been set up by the two energy giants to help create capabilities for the deep processing of natural gas, oil and other hydrocarbons in India, Russia and third countries as well as arranging for their deliveries of petrochemical products to the Indian and Asian Pacific markets.
