PETRONAS Block 52 Wells Confirm Oil and Gas Reservoirs Offshore Suriname

30 June 2026

PETRONAS, through its wholly-owned subsidiary PETRONAS Suriname E&P B.V. (PSEPBV), has recorded two new discoveries and achieved a successful appraisal in Suriname's offshore Block 52, bringing its cumulative achievements in the country to a total of eight successful wells and collectively unlocking recoverable resources of more than one billion barrels of oil equivalent.

The Caiman-1 exploration well, drilled in 90 m of water to a total depth of 5,065 m, encountered multiple oil-bearing Cretaceous sandstone intervals. The Swartzia Aspasia Complex-1 (SAC-1) exploration well, located 8 km east of Sloanea-1 gas discovery in 610 m of water depth, and drilled to a total depth of 4,560 m, intersected gas-bearing sandstone reservoirs. Drill stem testing (DST) demonstrated strong gas deliverability, indicating good reservoir quality.

The Roystonea-2 appraisal well, drilled 7 km north of Roystonea-1, confirmed the lateral extent of oil-bearing reservoirs, with DST results indicating strong oil productivity, further validating the quality and extent of the reservoir system.

PETRONAS operates Block 52 with 80 percent participating interest, while the remaining 20 percent is held by Paradise Oil Company N.V. (POC), a wholly-owned subsidiary of Staatsolie Maatschappij Suriname N.V. (Staatsolie). PETRONAS currently holds interests in eight offshore blocks in Suriname—Blocks 9, 10, 48, 52, 53, 63, 64, and 66.

PETRONAS’ Chief Operating Officer and Executive Vice President & Chief Executive Officer of Upstream, 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,” said Jukris.

These successes build on the commerciality declared for the Sloanea gas field in November 2025, with a final investment decision on its development targeted by the end of this year.

They further strengthen the case for multiple oil and gas developments in Block 52 and Suriname’s emergence as a significant deepwater hub in the Suriname-Guyana basin.

As part of its commitment to Suriname, PETRONAS has awarded scholarships to seven Surinamese students currently in their first semester at Universiti Teknologi PETRONAS (UTP) in Malaysia. These students are the first cohort from Suriname to pursue higher education in the country under the PETRONAS scholarship program.
