TotalEnergies and partners reached a positive final investment decision (FID) for the first oil development in Block 58, offshore Suriname. The project, named GranMorgu, will include production from the Krabdagu and Sapakara oil discoveries, where an appraisal drilling campaign completed in 2023 confirmed gross estimated recoverable resources of more than 750 million bbl of oil.
Sapakara and Krabdagu fields, in water depths of 100-1,000 m, will be produced through a system of subsea wells connected to a floating production, storage and offloading unit (FPSO) located 150 km (93 miles) off the Suriname coast (OGJ Online, Aug. 21, 2024). The 200,000 b/d unit is designed to accommodate future tie-back opportunities that would extend its 4-year production plateau, APA said in a release Oct. 1.
Total investment is estimated at $10.5 billion and first oil is expected in 2028.
TotalEnergies is the operator of Block 58 with a 50% interest, alongside APA Corp. (50%). Staatsolie Maatschappij Suriname NV, Suriname’s national oil company, intends to exercise its option to enter the development with up to 20% interest. Partners agreed that Staatsolie will contribute to the project from FID and will finalize its interest before June 2025.
GranMorgu will feature technology that minimizes greenhouse gas emissions, including an all-electric FPSO configuration with zero routine flaring and full reinjection of associated gas into the reservoirs, an optimized power usage with a waste heat recovery unit and deep-sea water cooling for improved efficiency, and installation of an advanced methane detection and monitoring system.
In addition to reaching approval for the Phase-1 Central Area Field Development, the partnership has retained optionality for further exploration in Block 58. This will allow the partnership to fully explore the significant remaining potential of the block in the proven trend, as well as untested plays.
