Top 10 Best Oil Companies to work for

Top 10 Best Oil Companies to work for


Oil remains a dominant energy source in the world, fueled by giant oil companies that fuel billions of barrels of petroleum products daily into energy-hungry economies. All this despite growing public concerns about climate change and measures to reduce the use of carbon-based fuels such as petroleum. True, oil prices have suffered from extreme volatility due to the COVID-19 pandemic and heightened trade tensions. But many of the world's major oil companies still generated significant revenues. Below we take a look at the top 10 oil companies in terms of 12-month rolling revenue (TTM). While Chinese and American companies make up half of the 10 companies, the main players are also from Saudi Arabia, Europe, and Russia. This list is limited to companies listed on the stock exchange in the United States or Canada, either directly or through ADR. Some foreign companies may produce semi-annual reports and therefore may have longer deadlines.
