PETRONAS unlocks more than 1 Bboe with latest Suriname discoveries

(WO) — PETRONAS has recorded two new discoveries and a successful appraisal well offshore Suriname, bringing its total successful wells in Block 52 to eight and unlocking more than 1 billion boe of recoverable resources. 

The company said the latest drilling campaign included the Caiman-1 exploration well, which encountered multiple oil-bearing Cretaceous sandstone intervals after reaching a total depth of 5,065 m in 90 m of water.

The Swartzia Aspasia Complex-1 (SAC-1) exploration well, drilled in 610 m of water approximately 8 km east of the Sloanea-1 gas discovery, intersected gas-bearing sandstone reservoirs. Drill stem testing confirmed strong gas deliverability and reservoir quality.

PETRONAS also completed the Roystonea-2 appraisal well, located about 7 km north of the Roystonea-1 discovery. The well confirmed the lateral extent of the oil-bearing reservoir, with testing indicating strong oil productivity.

PETRONAS operates Block 52 with an 80% interest, while Staatsolie subsidiary Paradise Oil Company holds the remaining 20%.

The latest results build on the declaration of commerciality for the Sloanea gas field in November 2025. A final investment decision on the development is targeted before the end of 2026.

PETRONAS said the discoveries further strengthen the case for multiple oil and gas developments in Block 52, located within the highly prospective Suriname-Guyana Basin.

"Our 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," said Mohd Jukris Abdul Wahab, PETRONAS chief operating officer and executive vice president and CEO of Upstream.
