Guyana will add a new medium-sweet crude grade to its export slate when Uaru Gold is introduced to the market, a report published by reports on 16 October 2026 stated. A preliminary assay seen by Platts, part of S&P Global Energy, gives the grade an API of 31.5 and a sulphur content of 0.54 per cent, and describes its quality as most similar to the country’s flagship Liza crude.
The reports article said Uaru Gold is expected to arrive on the market in December. The report framed the new grade as the fourth medium-sweet crude to emerge from Guyana’s production, placing it alongside the country’s existing medium-sweet offerings.
Assay details
The preliminary assay, as reported via Platts, recorded an API gravity of 31.5 and a sulphur content of 0.54 per cent for Uaru Gold. Those numeric particulars were presented in the reports summary of the Platts material.
Platts was identified in the report as the S&P Global Energy unit that had seen the assay. The reports item relayed those technical measurements without additional laboratory or commercial detail beyond the preliminary figures.
Uaru Gold’s measured properties were explicitly compared in the report to those of the Liza crude, which the article described as Guyana’s flagship grade. The comparison was framed in terms of overall quality similarity rather than identical specification.
Market positioning
Sources noted the expected December market debut but did not specify delivery mechanisms, volumes, or purchasers. The report focused on the grade’s classification and the assay values that underpin that classification.
The announcement of a fourth medium-sweet grade was presented as a development in Guyana’s crude portfolio. The article confined itself to the technical assay results and the timing cited for the new grade’s market introduction.
The reports item of 16 October 2026 is the source of the published details summarising the preliminary assay and the market timing. Platts, as part of S&P Global Energy, was credited with sighting the assay that supplied the technical figures.
Readers seeking further specification beyond the API and sulphur readings, such as detailed compositional analysis, anticipated cargo schedules or contracting particulars, would need to consult follow-up releases or the original assay documentation; the reports article relayed only the points noted above.
