Lack of technocrats.
Explanation:
There is a widely known phrase in mining industry in Africa, its called the "resource curse". In countries like Nigeria, which produces mammoth amount of Oil all year round, the proceeds from oil is not evenly distributed to better the lives of the masses. Profits derieved from oil is expected to help fund education and training of expats. It is not the case. Thereby, we hear of the oil curse.
It is widely believed and statististically proven that Africa lacks adequate and capable technocrats to harness its vast resources.
Africa owns the resources and the West have the brains to harness them. The Western countries have the right technologies and financial capabilities to explore and produce oil in Africa.
Africa is not as technologically bouyant as the West and does not have the right structure to tap its vast oil reserves. Technologies have to constantly be imported from foreign countries. Most companies believes that it is cheaper to import foreign technocrats with an excellent track record than to start training new ones and deploy them to work in their various climes.
Although, there has been a rigorous drive through indigenous policies to bring up more Africans into the oil industry.
