We need the IPI Pipeline but IMHO it is not going to be built because Pakistan does not have the money and it would be difficult to find a third party to finance it in the face of US opposition.
Besides, we are unable to safeguard the pipelines already in existence, it is reasonable to assume that it won’t be possible to police such a long pipeline and supply disruption would be the norm as BLA will blowing it up.
I agree that TAPI pipeline doesnot appear to be feasible and is probably nothing but a carrot offered to Pakistan to desist us from following up on IPI pipeline. Even if it is actually built, it would take a very long time.
It seems that only workable alternative is to go the LNG route. Qatar has the largest gas reserves in world and plenty of LNG for export. We can set up LNG receiving terminals along the coast and supply southern region with gas from LNG imports leaving indigenous gas to meet demand of the northern part.
