THE Petroleum and Gas Workers’ Federation of India, the largest federation of oil trade unions, has strongly opposed the action of the central government for handing over 15 oilfields of ONGC and OIL to private parties in the name of marginal oilfields auction. The government, under a policy adopted on September 2, 2015 after closing the New Exploration Licensing Policy (NELP), selected 67 oilfields for auction.
