Exxon Mobil's Guyana discovery is the king of the company's portfolio. The company has discovered more than 6 billion barrels of oil here.
The discovery is so big that it involves geopolitical risk that is worth paying attention too.
Overall, I expect the discovery to add several billion dollars in annual profit to the company's bottom line in the next 5-6 years.
Sulfur risks are overblown, as revealed by Exxon Mobil's own investigations.
