New Delhi, June 27
THE Director-General of Hydrocarbons (DGH) on Monday said that it would take at least a fortnight to estimate the size of the gas reservoir in Krishna-Godavari Basin (KG Basin) where Gujarat State Petroleum Corporation Ltd (GSPC) has discovered gas.
Speaking to Business Line, Mr Vinod Sibal, DGH, said, "At present production testing in the block is going on. Once this is over then we are going to evaluate it. However, the flow of the gas is good."
According to him, the discovery of gas is at a depth of about 4,700 metres and water depth is at around 80 metres. GSPC, on Sunday, said it has discovered an estimated 20 trillion cubic feet of gas reserves in an offshore exploration block in the Bay of Bengal. This comes close on the heels of ONGC announcing that it has made a significant gas discovery in the shallow waters of the KG Basin.
ONGC had said that gas was struck in a well drilled on the GS-15 prospect, located southwest of the Ravva oilfield, which was discovered by ONGC in 1987. The site is around 12 kilometres from the Amalapuram coast in Andhra Pradesh. The well was spudded on May 28 at a depth of 17.8 metres with a target depth of 2,500 metres. ONGC has indicated a significant hydrocarbon column or pay zone of around 45 metres at a depth of 1,684 metres to 1,760 metres.
Industry players said that if the reserves in the KG basin are proven, the GSPC discovery would be India's largest ever gas find.
Reliance Industries Ltd in 2002 had announced that it had found gas adjacent to GSPC's current discovery. The Reliance block is estimated to hold around 14 trillion cubic feet of gas reserves.
GSPC was awarded the shallow water block under the Government's third round of New Exploration Licensing Policy. India imports around 76 per cent of the crude of it processes.
The domestic gas output of around 80 million cubic meters a day meets only about 60 per cent of its demand.
