While official sources quote a figure of 100 tcf for gas reserves in the region, unofficial estimates peg the reserves at 200 TCF. This, says a report by equity brokerage house CLSA, could put India in the league of top 10 natural gas producers in the world.
Note that from what the lists show the 200 TCF number is for the Krishna/Godavari system alone. Less than 10% of the blocks here have been drilled. I suspect that people are being very conservative here.
Looks like I was being very conservative when I predicted 100 TCF for the East coast.
Once the entire East coast is drilled I would expect something like 5 times this number as the ultimate potential. 1000 TCF or so.
We will then be in the Iran league. Who woulda thunk it.
I TCF of Gas ~ 2 Billion barrels of oil. So you can do the math. Even a conservative estimate shows a 400 Billion Barrel equivalent reserve.
The reasons for this is given below.
“These are ancient river systems that have been depositing sediments here for a long time. But as the basins are shallow, most sediments, and therefore hydrocarbons, would have found their way into the deep and ultra deep waters (below 400 meters depth). That is where the real potential of the region lies,” said an industry analyst. “Oil companies like Cairn, ONGC, Gujarat State Petroleum Corporation (GSPC) and Reliance Industries (RIL) have found good working petroleum systems -- reservoir and source rocks Can't stress enough how important a note this is. There are only a handful of places in the world this is true. almost all have proven wildly productive.that promise great discoveries in the coming years,” he said.
The Krishna, Godavari & Cauvery basins are thought to originate from the Pangean era. So have been flowing in their present basins for ~ 400 million years or so.
Note that this is not easy money. This gas is expensive to access and produce. Still it should provide the energy for our economy to grow while also creating some wealthy technologically powerful industries. It is going to require the sweat of literally millions of people to bring to land. Not quite Arabia.
Also note that similar structures occur off the East coast as well. It is even harder there because the continental margin is 200-300 km from the shore in most areas. So stay tuned, many more TCF's to come.
