Guyana’s Uaru Gold crude to resemble Liza’s medium-sweet grade – S&P Global
Guyana's Uaru Gold crude, set to debut in December, has an API gravity of 31.5° and sulfur content of 0.54%, resembling the Liza grade. Produced by the Errea Wittu FPSO, it will add 250,000 b/d capacity. ExxonMobil operates four existing grades from the Stabroek Block, each with distinct profiles. Uaru Gold's launch is expected to push Guyana's production above 1 million b/d.
How this was made
The 30-second read
Why it matters
The debut of Uaru Gold offers incremental growth but lacks a game‑changing catalyst.
Market read
New crude grade adds modest upstream capacity; relevance primarily to oil‑sector analysts and refiners.
What to watch
Actual refinery uptake and transportation constraints could limit the grade's market impact.
Background
ExxonMobil and partners are expanding Guyana production with the Errea Wittu FPSO, targeting 1.7 MMboe/d by 2030.
Ticker impact
ExxonMobil's new Uaru Gold crude grade will add ~250,000 b/d capacity and enter market in December, expanding Guyana sweet‑crude supply.
likely slight upside as market prices in added capacity and grade similarity to Liza.
Uaru Gold matches existing Liza grade, offering incremental production without major cost changes; impact is incremental rather than transformational.
Market effects
Adds medium‑sweet crude capacity, may improve refinery feedstock options and modestly support sweet‑crude pricing.
Guyana output above 1 M b/d could affect Caribbean and Latin American supply dynamics.
Provides a modest increase to global sweet‑crude inventories, unlikely to shift overall oil market balance.
Counterpoint
The new grade may not materially affect pricing if demand for medium‑sweet crude remains flat.
