This slope business is probably an urban legend. If we can get gas from Balochistan, why not oil?
Moreover this oil pouring out of Iran and getting into Pakistan does not make sense. Just look at this map for all the Iranian oil and gas fields. None of them is in Iranian Balochistan or near Pakistani border. In fact they all are located next to Iraqi border. If Iraq didn’t sign such a strange agreement, how on earth Pakistan would. Just look at this linky to see the “picture”.
May be we have a real geologist guppy who can enlighten us. Until then, this is clearly a conspiracy theory.
