ExxonMobil has produced the 1 billionth barrel of oil from Guyana’s deepwater Stabroek Block.

Production began in December 2019 at the Liza Field, just under five years since it was discovered.

Currently four FPSOs are in operation—Liza Destiny, Liza Unity, Prosperity and ONE GUYANA—with combined production capacity of more than 900,000 bbl/d.

A fifth should be in service by the end of the year on the Uaru Field, with startup of the sixth project, Whiptail, anticipated next year and followed by Hammerhead in 2029.

ExxonMobil estimates total resources on the block at just under 11 Bboe, and it expects to have eight active offshore developments by 2030.

Next FPSOs coming online:

  • Uaru: Expected startup by year-end

  • Whiptail: Expected 2027

  • Hammerhead: Planned for 2029
