The oil and gas industry is the one of the most important industries in many countries. The economies of Middle Eastern countries are based on oil and natural gas. It is also the largest sector of the Russian economy. As a commodity, crude oil prices are volatile and fluctuate based on an infinite number of reasons ranging from political to supply and demand. For example, a bunch of rag tag rebels in Nigeria setting fire to a pipeline can cause the global price of oil to shoot up.
