The government on Sunday cut the price of natural gas produced from difficult areas like deep sea KG-D6 block of Reliance Industries, marginally to USD 9.87 per million British thermal unit in line with softening of benchmark international gas prices, an official notification said. However, the price of gas that is used for making CNG for fuelling automobiles or piping to household kitchens for cooking purposes will remain unchanged due to a price cap that is set at 30 per cent less than market rates such as that paid to Reliance.
