As many as 63 discovered oil and gas are being surrendered by state-owned Oil and Natural Gas Corp (ONGC) as they were found to be uneconomic for a large firm with huge overheads to develop or bring to production. Smaller firms with a fraction of operating cost can develop them at much faster and economic rate.
Oil India Ltd (OIL) has surrendered 6 marginal fields.
"We are looking at marginal field auction round on a new revenue sharing model soon," Pradhan said on the sidelines of Geo India 2015 conference here.
This is a shift from the much-criticised Production Sharing Contract (PSC) regime where blocks were allocated to firms that bid highest amount of work in the area.

It allowed the firms to recover all their cost before sharing profits with the government, a regime which was criticised by CAG as one that provides incentive to operators to keep raising cost so as to postpone government share.
"We are working on fast track for the auction of marginal fields," he said adding the round is likely in next few months.
His ministry is currently preparing the policy guidelines for the auction, and if the Cabinet Committee on Economic Affairs (CCEA) approves, it would mark shift to the new bidding regime as was recommended by the C Rangarajan Committee.
Pradhan said the policy regime for the 10th exploration licensing round is under discussion.
Nine rounds of auction have taken place since 1999 under New Exploration Licensing Policy (NELP) as per the PSC regime.
Marginal fields were given to ONGC before the licensing rounds on nomination basis. Hydrocarbons resources are locked up in these fields, but they cannot be produced economically on a standalone basis, or with a conventional approach.
Of the 165 fields, with total ultimate reserves of 340 million tons, operations are going on in 139 and work is yet to start on 26.
