ONGC is in talks to sell up to 30% stake in its Krishna-Godavari DWN 98/2 block to BG Exploration and Production, India or Italian exploration company ENI. ONGC wants a partner that can provide technology for deep sea exploration, where BG and ENI have expertise. Selling a 30% stake would give technological assistance while maintaining control over decision making. The block holds over 6 trillion cubic feet of gas reserves and ONGC plans to invest $3.6 billion to develop it.
