ONGC's USD 2.4-bn Mozambique deal under Oil Min scanner

The inquest by the ministry was acknowledged by senior company officials, who said details have been provided on multiple occasions.

Sources said Videocon was in 2012 willing to sell its stake to OVL at a small premium to the price Thailand's PTT Exploration and Production paid for acquiring an 8.5 per cent stake in the same block from Cove Energy for 1.22 billion British pounds (USD 1.9 billion at exchange rate prevalent at that time).

The 10 percent stake, they said, was available to OVL for about USD 2.3 billion or so but the company a year later paid USD 2.475 billion to Videocon.

An e-mail sent to ONGC Chairman Dinesh K Sarraf, who was Managing Director of OVL at the time of the deal, for comments received a response from the company stating: "There is no basis to this allegation and ONGC Videsh strongly refutes it." OVL had followed up the Videocon purchase by buying another 10 per cent stake in the same Offshore Area 1 of Mozambique from US energy major Anadarko Corp for USD 2.64 billion in 2014.

A year later, Anadarko in its annual filings with the US Securities and Exchange Commission said it made a "gain" of USD 1.5 billion or over 62 per cent of the purchase price, from the sale of 10 per cent interest in Offshore Area 1.

Woodlands, Texas-based energy exploration company Anadarko continues to be the operator of the block, with its stake reduced to 26.5 per cent from 36.5 per cent after the deal.

Presently, OVL has 16 per cent stake in Offshore Area 1, which holds as much as 75 trillion cubic feet of gas reserves.

OIL has 4 per cent and a unit of Bharat Petroleum Corp Ltd (BPCL) another 10 per cent stake.

Other partners in Area 1 include Mitsui with 20 percent stake, ENH (15 per cent) and PTTEP (8.5 per cent).

Gas from the block is to be converted into liquefied natural gas (LNG) for transportation by ships to markets like India.
