FOR nearly three years now, privatised offshore oil and gas fields at Panna and Mukta in the Arabian Sea were producing oil and gas unhindered. But a recent writ petition filed by the Centre for Public Interest Litigation and the National Alliance for People's Movement threatens to stir up a hornet's nest. The petition alleges many irregularities in the contract awarded to a joint venture between Enron Oil and Gas (30 per cent), Reliance Industries (30 per cent) and ONGC (40 per cent) to produce and sell oil and gas from these fields. The basic contention: that Reliance bribed then petroleum minister Satish Sharma to wangle a deal that would cause a "loss of several thousands of crores to the public exchequer".
