Overview

Guyana (offshore). ExxonMobil (45%, operator), Chevron (30%, via its 2025 acquisition of Hess), CNOOC (25%). ~900,000 bpd capacity from four FPSOs by late 2025; >11 bn bbl discovered. The fastest-growing oil province outside the Middle East.

Geopolitical context

Guyana went from zero to one of the world's highest per-capita oil producers in five years. Venezuela claims the Essequibo region (two-thirds of Guyana's territory) and held a referendum on annexing it in 2023. The Stabroek shares that Chevron won in arbitration against ExxonMobil in 2025 give two US majors and a Chinese state firm a stake in keeping the region stable.
