PARAMARIBO, SURINAME – Two Guyana prospects – Lanternfish-1 and Blacktip-1 – have been ranked among the world’s most significant high-impact wells targeted for drilling in 2025, according to S&P Global Commodity Insights.
These wells were featured on S&P’s global map of priority exploration targets at the Suriname Energy Oil & Gas Summit (SEOGS) taking place this week in the South American country.
Ricardo Bedregal, Executive Director of Upstream for Latin America at S&P, disclosed that each prospect is estimated to hold approximately 150 million barrels of oil.
The Lanternfish-1 well, as previously confirmed by Hess Corporation, is situated near the Fangtooth discovery. It was being drilled to evaluate whether it can be incorporated into a potential development for ExxonMobil’s seventh floating production, storage and offloading vessel (FPSO). However, Hammerhead has already been selected for that development phase. Still, the strategic positioning of Lanternfish could allow for future integration.
Guyana was not alone in gaining global attention.
According to the S&P map, Suriname’s Walker-1, Brazil’s Bumerangue and Morpho, and Peru’s Kametza 1EXP were also listed among Latin America’s key high-impact wells for 2025.
Across Africa, Europe, Asia, and Oceania, over 30 other wells were identified, highlighting a robust global outlook for exploration activity this year.
ExxonMobil operates the Stabroek Block – where these wells are located – with a 45% interest, while Hess holds 30%, and CNOOC owns the remaining 25%. Since the first major find in 2015, the consortium has made over 11 billion barrels of oil-equivalent discoveries on the block.
