Explanation:

Oil price boom after the world war wasn't necessarily caused by oil surplus.

The world war consumed a lot of oil as a fuel for military airplanes , ships, and tanks. This large amount of consumption actually made oil reach scarcity level after the war.

This made the amount of demand for oil consumption outnumber the amount of oil supply in the market, which led  to the price boom in the 1900s.
