15 Biggest Oil Companies in USA

In this article we are going to present our list of the 15 biggest oil companies in USA.

The oil industry got clobbered in 2020 and continues to face volatility amid the coronavirus crisis. However, oil investors are hopeful as countries begin to vaccinate their populations and industries restart their operations. Recently, the International Energy Agency said in a report that it expects oil demand to hit 100.6 million barrels for the first time since late 2019 in the last quarter of 2022. However, the agency noted that the slow pace of vaccinations in Asia could dent the expected recovery.

Nonetheless, analysts believe that oil companies have seen the rock bottom and are set to gain in the coming months. Despite the global push towards renewable energy and price fluctuations, the oil industry is expected to thrive for years to come, with major oil companies like Devon Energy (NYSE:DVN), Phillips 66 (NYSE:PSX), Marathon Petroleum (NYSE:MPC), Chevron (NYSE:CVX), Exxon Mobil (NYSE:XOM), Chesapeake Energy (NYSE:CHK) and Occidental Petroleum (NYSE:OXY) expecting huge profits.
