Leading oil and gas producers in the U.S. based on revenue 2021

ExxonMobil is the largest United States-based oil and gas producing company. In the latest reporting period before August 2021, ExxonMobil generated 214.66 billion U.S. dollars in revenues. ExxonMobil’s revenue was significantly higher than its competitors, earning nearly 100 billion U.S. dollars more than Chevron, which ranked second that same year.

ExxonMobil’s main operations and locations

Based in Irving, Texas, ExxonMobil is consistently ranked as one of the top oil and gas companies worldwide based on revenue. The company has early origins in John D. Rockefeller’s Standard Oil Company from the 1880s but became the entity it is today when two major oil companies, Exxon and Mobil, merged in 1999. The company is one of the leading global oil refiner, with refineries in 21 countries. The majority of ExxonMobil's refining capacity is in North America and Europe.

Two decades of cutbacks

ExxonMobil's revenue has seen a staggering decline in the past decade. While having been consecutively ranked among the largest worldwide companies in the late 2000s and early 2010s, the 2015/16 oil glut has eaten at the company's annual returns. The 2020 oil crisis has further reduced ExxonMobil's revenue to the lowest value yet.
