Petronas Suriname Exploration and Production Company, a wholly-owned subsidiary of Malaysian oil and gas heavyweight Petronas, has confirmed two discoveries and successful appraisal activity in Block 52 offshore Suriname.
Petronas explains that Cayman-1 An exploratory well was drilled in 90 meters of water to a total depth of 5,065 metres, encountering multiple intervals of oil-bearing Cretaceous sandstone. the Swartsia Aspasia Complex-1 (SAC-1) An exploratory well located 8 kilometers east Slonia-1 Gas was discovered at a depth of 610 meters of water and drilled to a total depth of 4,560 metres, intersecting with gas-bearing sandstone reservoirs.
Drill stem testing (DST) showed strong gas conductivity, indicating good reservoir quality. the Rustonia-2 An appraisal well was drilled 7 km north Rustonia-1The lateral extent of the oil-bearing reservoirs was confirmed.
DST results indicate strong oil productivity, further confirming the quality and extent of the reservoir system. The two discoveries and appraisals at Block 52 in Suriname bring Petronas’ cumulative achievements in the country to eight wells.
As a result, this collectively unlocks recoverable resources in excess of 1 billion barrels of oil equivalent. Block 52 is operated by Petronas with an 80% participating interest, while the remaining 20% is held by Paradise Oil Company (POC), a wholly-owned subsidiary of Staatsolie Maatschappij Suriname (Staatsolie).
Petronas currently holds interests in eight offshore blocks in Suriname: 9, 10, 48, 52, 53, 63, 64, and 66. The latest discoveries build on the commercial viability of the Slonia gas field announced in November 2025, with a final investment decision (FID) on its development targeted by the end of the year.
Muhammad Jokris Abdel WahabPetronas Chief Operating Officer, Executive Vice President and Chief Executive Officer commented: “Eight successful wells have been opened in Suriname with recoverable resources in excess of 1 billion barrels of oil equivalent, reflecting the strength of our technical capabilities, disciplined execution and strong partnership in Suriname.
“Block 52 is located within a highly prospective corridor, Golden Lane, and we remain focused on translating this resource base into long-term value for Suriname and Petronas.”
The company claims that the hydrocarbon discoveries further strengthen the case for the development of several oil and gas projects in Block 52 and the emergence of Suriname as an important deepwater hub in the Suriname-Guyana Basin.
Petronas is actively growing its global oil and gas portfolio, as evidenced by The beginning of the drilling campaign With TotalEnergies off the coast of Papua New Guinea.
