With a 50% participating interest, Petronas Suriname E&P is the operator of Block 52, which has an area of 4,749km².

The exploration block is part of the Suriname-Guyana basin and is north of the coast of Paramaribo, the capital of Suriname.

Petronas Suriname E&P also operates Block 48 with a 100% participating interest.

Additionally, in the neighbouring Block 53, it is a partner with a 30% non-operating participating stake.

In 2022, the Baja-1 oil discovery was made in Block 53.

Petronas executive vice-president and CEO of upstream Datuk Adif Zulkifli said: “Petronas views the Roystonea-1 oil discovery as a positive development towards realising our differentiated barrel strategy for international upstream ventures, focusing on a material discovery with minimal contaminants.”

Petronas vice-president of exploration Mohd Redhani Abdul Rahman said: “The success of Roystonea-1 is expected to drive further exploration for commercially viable hydrocarbon resources in the surrounding areas.

“Petronas will continue to work closely with the host authority, Staatsolie, and partners to unlock Suriname’s hydrocarbon potential.”

In July 2023, Petronas Carigali, a subsidiary of the Malaysian-Government company, made six oil and gas discoveries in five blocks offshore Malaysia.
