Petronas said that these wells have unlocked total recoverable resources exceeding one billion barrels of oil equivalent.
Block 52 is operated by Petronas with an 80% interest, while Paradise Oil, a wholly owned subsidiary of Staatsolie Maatschappij Suriname, holds the remaining 20%.
Petronas also holds stakes in seven other offshore blocks in Suriname.
According to Petronas, the Caiman-1 exploration well was drilled in 90m of water to a depth of 5,065m and encountered various oil-bearing Cretaceous sandstone intervals.
Meanwhile, the Swartzia Aspasia Complex-1 (SAC-1) exploration well was drilled in 610m of water to a depth of 4,560m, where it encountered gas-bearing sandstone reservoirs. SAC-1 is situated roughly 8km east of the earlier Sloanea-1 gas discovery.
Drill stem testing at SAC-1 indicated strong gas deliverability and good reservoir quality, the company said.
The Roystonea-2 appraisal well, located 7km north of Roystonea-1, has confirmed the lateral extent of oil-bearing reservoirs.
The drill stem tests from this well also demonstrated strong oil productivity, supporting the quality and extent of the reservoir system.
These recent discoveries follow a commerciality declaration for the Sloanea gas field made in November 2025, with a final investment decision on its development expected by the end of this year.
Petronas chief operating officer and upstream executive vice-president and CEO Mohd Jukris Abdul Wahab said: “Eight successful wells in Suriname with recoverable resources of more than one billion barrels of oil equivalent unlocked reflect the strength of our technical capabilities, disciplined execution and strong partnership in Suriname.
“Block 52 sits within a highly prospective corridor, the Golden Lane, and we remain focused on translating this resource base into long-term value for Suriname and for Petronas.
“We thank Staatsolie for the support and collaboration in advancing our progress in the country. Petronas remains committed to Suriname’s broader ambitions in building local capability, developing human capital and creating shared value for both our nations.”
Separately, Vestigo Petroleum, a subsidiary of Petronas Carigali, has reported a fire at its West Lutong Vent A facility offshore Sarawak in Malaysia.
The fire was contained and the underlying cause is currently under investigation.
Vestigo is coordinating with the appropriate authorities and has implemented precautionary steps to minimise any potential risks. No injuries occurred and no staff members were affected.
In March this year, Petronas reported its first hydrocarbon discovery at the Barokah-1 exploration well in the North Ketapang production sharing contract area, offshore East Java, Indonesia.
