Petroleum is referred to as 'black gold' because when crude oil is extracted from the land it is black in colour. People call it gold because of its oils and value. It is very difficult to find. As both Coal & Petroleum handles lot of money so they called as Black Gold. Crude oil comes out of the ground as black, so it is called as black gold.
