The US$55 Billion Milestone That Should Worry Every Guyanese Investor

ExxonMobil has fully recovered the US$55 billion it spent developing the Stabroek Block since 1999. The company’s CFO, Neil Hansen, is now using Guyana as a sales pitch to other oil-rich nations, telling resource owners that if they want their costs “recovered quickly,” Exxon is the “partner of choice” .

For Guyanese investors watching from abroad, this milestone cuts two ways. Yes, Guyana’s share of production has climbed to 39.8%, up from roughly 12.5% during the peak cost-recovery years . That’s real money flowing into the Natural Resource Fund, which held nearly US$4 billion as of May 2026 .

But the number that should command your attention isn’t 39.8%. It’s the mechanism behind it—and what happens next.
