PARAMARIBO, SURINAME – TotalEnergies believes Suriname’s Block 58 still holds more oil potential beyond the 750 million barrels already underpinning the GranMorgu development, its Suriname General Manager Artur Nunes da Silva.
Nunes da Silva made the comment during a presentation on GranMorgu, the country’s first major offshore oil development. The project is being advanced by TotalEnergies, APA Corporation, and Staatsolie from the Krabdagu and Sapakara fields offshore Suriname. Those two fields will supply the floating production, storage and offloading vessel (FPSO), being built for the development.
The fields sit in deep reservoirs of about 4,500 meters and hold estimated reserves of 750 million barrels. But Nunes da Silva said TotalEnergies does not view that figure as the final production ceiling for the block.

“I can tell you that my belief is that the prospectivity is still in Block 58 and we’ll have more at the end,” he said. “I don’t want to create more expectations.”
Nunes da Silva said TotalEnergies, Staatsolie, and APA are working to capture that upside.
“I can tell you that you’ll produce, through this FPSO, more than these 750 million barrels,” he added. “We are working on that with Staatsolie, with our partner APA, and we are confident that we’ll manage to do so.”
The comments point to the wider resource potential still being assessed in Block 58, even as GranMorgu moves through execution. Nunes da Silva reminded delegates that the development followed a 14-well exploration and appraisal campaign carried out from 2020 to 2023.
He said that campaign confirmed enough resources to move GranMorgu toward the final investment decision. It also helped define the development plan now being executed.
The project includes 32 wells, about 200 kilometers of subsea lines, and an FPSO that will be the most visible part of the offshore development. Nunes da Silva said drilling will continue after first oil to build production and support plateau output from the FPSO.
“When we are at first oil, we are just at 80% progress of the project because, in fact, after the first oil, we continue drilling,” he explained.
Nunes da Silva said the production phase will matter most for Suriname because it will generate long-term revenue, jobs, and activity over 20 to 25 years. He also said there is potential to extend production beyond that period.
