Overview of the Integrated Oil Companies Field

To say that the integrated oil companies sector is huge is an understatement.  At nearly $400 billion, the oil industry accounts for 3.8% of the global economy.

Integrated oil companies in the United States generate little more than $180 billion in sales each year and employ 9.8 million people.  This accounts for 5.6% of all U.S. employment.

Currently, the integrated oil companies sector industry is expected to be worth $6.819 trillion in 2023.  This is not least surprising as the industry produces about 6.8 billion barrels of oil yearly.
