Texas, North Dakota, New Mexico, Oklahoma, and Alaska are the top oil-producing US states. ExxonMobil (XOM), Chevron (CVX), BP (BP), and Royal Dutch Shell (RDS.A) are among the top global oil companies.
Iran’s oil production
Iraq contributed ~5% of total global crude oil production while Iran was the seventh-largest producer, accounting for ~4% of the total global production. So, with roughly 4.47 million barrels per day of production, Iran’s contribution to global oil production isn’t insignificant. The top ten oil producers account for 70% of the total global crude oil production.

The United States also happens to be the largest consumer of crude oil worldwide. According to 2016 data, it accounted for 20% of the global oil consumption. Next come China and India. The EIA ranking defines “oil” to include crude oil, all other petroleum liquids, and biofuels.
