Suriname has recorded 65 offshore wells drilled as of November 2025, according to new data published in Staatsolie’s GeoAtlas of Suriname. The report notes that these wells “included mainly exploration wells and a few appraisal wells”, demonstrating the country’s continued push to define its offshore potential.
Staatsolie’s GeoAtlas also documents a century of onshore activity in the coastal plain, where “400 exploration wells have been drilled…of which the majority have oil shows in the Cretaceous and Tertiary”. Since production began in 1982, “a total of 3,800 production wells with an average depth of 350 meters have been drilled”, most of which were still producing in 2025.

The GeoAtlas outlines the seismic groundwork supporting these campaigns. In the coastal plain, acquisition totals “approximately 30,000 km 2D seismic and 145 km² 3D seismic”. Offshore acquisition is far more extensive, with “approximately 164,000 km 2D seismic and 100,000 km² 3D seismic” compiled to date.
The well count comes as operators ramp up activity across multiple blocks. TotalEnergies’ Macaw-1 in Block 64 is among the most closely watched wells of 2025, part of a wider drilling schedule that includes planned wells in Block 52 and Chevron’s program in Block 5.
