The World’s 10 Biggest Oil and Gas Companies

Note: to see the bigger version of this infographic, click here.

Today’s infographic not only ranks oil producers based on factors such as barrel production per day, but it also compares data from a decade ago with today’s information for better perspective.

From 2005 to 2015, global oil usage has only increased from 83 million to 93 million bpd (1.13% CAGR). However, the overall rate at which the Top 10 has grown production has been at a 1.29% CAGR pace, and their production now makes up about 58% of all global production.

The companies with the most impressive increases over this time are all state-owned. Saudi Aramco, the world’s largest producer, increased production from 10.8 million bpd (2004) to 12 million bpd (2014). Rosneft, National Iranian Oil, Petrochina, and Kuwait Petrol Corp all saw sizeable increases. The only company to see a big decrease was also state-owned (Gazprom).

Oil and gas continues to make up the majority of the global energy mix with 33% and natural gas at 24%. That said, based on the CAGRs above, it does seem that we are making progress in tapering the growth of production. Human population and the economy are growing at rates higher than 1.13%, so that means oil is giving up ground to other energy sources.

Charted: Global Uranium Reserves, by Country

We visualize the distribution of the world’s uranium reserves by country, with 3 countries accounting for more than half of total reserves.

There can be a tendency to believe that uranium deposits are scarce from the critical role it plays in generating nuclear energy, along with all the costs and consequences related to the field.

But uranium is actually fairly plentiful: it’s more abundant than gold and silver, for example, and about as present as tin in the Earth’s crust.

We visualize the distribution of the world’s uranium resources by country, as of 2021. Figures come from the World Nuclear Association, last updated on August 2023.

Ranked: Uranium Reserves By Country (2021)

Australia, Kazakhstan, and Canada have the largest shares of available uranium resources—accounting for more than 50% of total global reserves.

But within these three, Australia is the clear standout, with more than 1.7 million tonnes of uranium discovered (28% of the world’s reserves) currently. Its Olympic Dam mine, located about 600 kilometers north of Adelaide, is the the largest single deposit of uranium in the world—and also, interestingly, the fourth largest copper deposit.

Despite this, Australia is only the fourth biggest uranium producer currently, and ranks fifth for all-time uranium production.

Figures are rounded.

Outside the top three, Russia and Namibia both have roughly the same amount of uranium reserves: about 8% each, which works out to roughly 470,000 tonnes.

South Africa, Brazil, and Niger all have 5% each of the world’s total deposits as well.

China completes the top 10, with a 3% share of uranium reserves, or about 224,000 tonnes.

A caveat to this is that current data is based on known uranium reserves that are capable of being mined economically. The total amount of the world’s uranium is not known exactly—and new deposits can be found all the time. In fact the world’s known uranium reserves increased by about 25% in the last decade alone, thanks to better technology that improves exploration efforts.

Meanwhile, not all uranium deposits are equal. For example, in the aforementioned Olympic Dam, uranium is recovered as a byproduct of copper mining occurring at the same site. In South Africa, it emerges as a byproduct during treatment of ores in the gold mining process. Orebodies with high concentrations of two substances can increase margins, as costs can be shared for two different products.
