Serious question: How economically/technically viable is it to get that gas?
Just to give you an example, Russia's oil is profitable at around 60 Dollars per Barrell, Saudis can go lower and US shale gas is only attractive when oil prices are really high. Its the same story with gas.
Not an expert but its apparently pretty deep in the ocean, so that makes it a bit expensive, we need to build all the infrastructure from zero so thats a very high initial investment too.
But it all depends on the market price of gas and needs to be put in perspective. Even if the price is higher it means less dependence on foreign sources, more of the money stays inside the country as opposed to abroad. So even at high costs will be worth it. If the government can be trusted and the reserves are as big as announced, that the economies of scale will help with lowering the cost of pumping that gas out the ocean. But we dont know the specifics, but higher volumes and higher gas prices make it more feasible and profitable.
710 bcm will be enough to supply the entire country with gas for around 10-15 years if consumed at once or if its rationed appropriately at 10-30% of annual consumption for a longer period. This would enable us to balance out a gas market crisis like recently, where we could raise the output instead of importing very expensive gas from abroad.
It will help with the current account deficit, but dont expect any magic and the imports to disappear altogether. The government needs to be smart about this money.
If they invest the profits wisely in renewables, hydrogen etc, we could use the gas to lower our energy imports for good. If they use it for election economics and nepotism. We won't be any better than all the other developing countries rich in energy, but no gain for the average citizen.
