April 25, 2012 Hardy Oil & Gas has agreed to relinquish a deepwater block in the Krishna-Godavari basin after its Indian partner and operator, Reliance Industries, said that the block was not viable. Reliance announced that it was surrendering 10 blocks, including D9, bringing down its oil and gas portfolio to 17 exploration blocks. The company continues to supply gas from its D6 and Panna-Mukta & Tapti fields. Reliance had discovered gas in the D9 block last year, but after drilling three exploration wells and analysing geo-scientific data the company found that the block's hydrocarbon potential was low. Block D9 is located in the same basin as D6, India's biggest gas field. Of the 10 blocks relinquished by Reliance, BP is partner in three. Reliance had sold 30% stakes in 21 oil and gas blocks to the British energy major for $7.2 billion.
