Billionaire Mukesh Ambani-run Reliance Industries Limited began gas production from the Krishna-Godavari basin in April, 2009, and its 60 million standard cubic metres per day output led to a 75 per cent jump in natural gas availability in the country to 140 mmscmd.
"Last year, India had the highest increase in production of natural gas worldwide. And I just checked, it also had the highest corresponding increase in consumption in natural gas worldwide," BP Plc Group chief economist Christof Ruhl said.
The jump in natural gas production in India was possible because the government allowed private sector firms to take a lead in exploration for hydrocarbons.
"When you look at countries where gas production is heavily government-controlled, like Russia, they had the biggest decline in gas production and consumption," he said.
"When you look at countries where new technologies have been developed like unconventional shale gas in the US. . . it was because they have an investment environment which is very competitive," he said.
Shale gas, trapped in sedimentary rocks, is said to hold the potential of doubling gas output in US.
Ruhl said that it was very clear who was left behind, as countries where natural resources were tightly controlled were less flexible.
Ruhl said the recent Supreme Court ruling in the Ambani gas dispute will help investment in the sector.
For investors, 'rule of law' and 'sanctity of contracts' they sign is important, he said. The court in May upheld the provisions of the production sharing contract an explorer enters into with the government for oil and gas prospecting.
It said the PSC gives the government the right to approve a gas price and fix its users, rejecting Anil Ambani Group firm Reliance Natural Resources Limited's claim for gas from Reliance Industries Limited at subsidised rates.
"That (judgment) has certainly improved stability and the sanctity of contract," he said. "That was a step into the right direction."
