Nigeria, the largest economy in Africa. It is country of great diversity and culture. Its oil reserves are huge.
From the BP Statistical Review of World Energy:-
One can see Nigeria’s oil wealth. It has 37.1 thousand million barrels of oil in its proven reserves.
What is that worth ?
One Barrel of oil is today worth $63.05 = £40.11
So 37,100,000,000 barrels x £40.11 = £1,488,081,000,000
That is a large number, = £1,488 Biion = £1.48 trillion, that is equivalent to the whole of UK’s annual GDP.
