French supermajor TotalEnergies, in partnership with APA Corporation and Staatsolie, is advancing its activities in Block 58 offshore Suriname. The plan includes drilling a new exploration well, with spudding anticipated in the late fourth quarter of this year. APA has allocated approximately $50 million to cover the costs of this exploration drilling campaign.

Development and Production Plans

Following the exploration phase, the focus will shift to developing the GranMorgu field, with production start-up targeted for mid-2028. The partners have chartered two drilling rigs from Noble Corporation—the Noble Discoverer and the Noble Valiant—which are scheduled to begin three-year contracts in Suriname in October 2026. These rigs will be used to drill development wells for the GranMorgu project.

GranMorgu Field and FPSO Details

The GranMorgu field is located approximately 150 kilometres off the coast of Suriname and holds estimated recoverable reserves exceeding 750 million barrels of oil. Production will be handled by a large, all-electric floating production, storage and offloading (FPSO) vessel, which is being built by SBM Offshore. This FPSO will have a processing capacity of 220,000 barrels of oil per day and 500 million cubic feet of natural gas per day. Its design includes provisions to accommodate future tie-back opportunities, which would help extend its production plateau.

Partnership Structure

TotalEnergies operates Block 58 with a 40% working interest. Its partners are APA Corporation, which also holds a 40% stake, and the Surinamese state-owned company and market regulator, Staatsolie, which holds the remaining 20%.
