Suriname’s offshore basin is being shaped by a mix of international operators and partners, with exploration wells drilled across multiple contract areas, according to a February 2026 map from Staatsolie.
The acreage sits offshore within the Guyana-Suriname basin, where production sharing contracts signed between 2012 and 2025 define who is operating and where drilling is taking place.
Open acreage accounts for the largest share at 74,955 square kilometers. It remains unlicensed, with no operator, no partners, and no wells identified.

Activity is concentrated across licensed offshore blocks held by companies including TotalEnergies, PETRONAS, Shell, Chevron and PetroChina, alongside partners such as APA Corporation, Hess, QatarEnergy and Staatsolie.
Block 58, operated by TotalEnergies with APA and Staatsolie, spans 5,833 square kilometers and shows the highest concentration of drilled wells on the map, including Maka Central-1, Sapakara West-1, Kwaskwasi-1, Keskesi East-1 and Baja-1. Two of these discoveries are supporting plans for Suriname’s first offshore oil development, GranMorgu.
Block 52, operated by PETRONAS with Staatsolie, covers 4,750 square kilometers. The map identifies wells including Roystonea-1 and Sloanea-1, with the block under assessment for a possible development.
