TotalEnergies takes steps toward FID on Block 58, offshore Suriname

TotalEnergies SE has taken several steps towards taking a final investment decision for development on Block 58 offshore Suriname.

Speaking at the 2024 Suriname Energy Oil and Gas Summit, Javier Rielo, senior vice-president Americas, exploration and production for TotalEnergies, and Annand Jagesar, chief executive officer of Staatsolie Maatschappij Suriname NV, the Suriname national oil company, said a decision is expected in this year’s fourth quarter for a production start-up in 2028.

Engineering studies are progressing for development of Sapakara and Krabdagu fields, with combined recoverable resources estimated above 700 million bbl with the integration of water alternating gas injection technology to maximize recovery, the companies said in a release June 5.

Ocean Bottom Node (OBN) seismic technology will also play a role in maximizing resources and the placement of the development wells, as well as identifying resource upsides. A first OBN campaign covering 900 sq km will be carried out in this year’s second half.

TotalEnergies in 2021 confirmed a single, blocky sand that is full to base with black oil in Block 58 (OGJ Online, July 29, 2021). Sapakara South-1, an appraisal well on the eastern edge of the Sapakara area, encountered about 30 m (98 ft) of net black oil pay in a single zone of high-quality Campano-Maastrichtian reservoir. Sapakara South-2 (SPS-2) appraisal well, the second appraisal well to test the previously reported discovery, encountered about 36 m (118 ft) of net oil pay in high-quality reservoir. In 2023, TotalEnergies advanced work to drill two appraisal wells at the Krabdagu discovery.

These fields, in water depths of 100-1,000 m, are expected to be produced through a system of subsea wells connected to a floating production, storage and offloading unit (FPSO) sited 150 km off the Suriname coast, with an oil production capacity of 200,000 b/d.

A final agreement between TotalEnergies and Staatsolie on the size of the area to be developed has been signed and the hull for FPSO has been secured, the companies said. 

TotalEnergies is operator of Block 58 with a 50% interest, alongside APA Corp. (50%). Staatsolie has the option to enter the development project with up to 20% interest upon FID.
