Eni SpA (NYSE: E), an Italian energy giant, has announced a major new oil discovery in the Yopaat-1 EXP exploration well in Block 9, located approximately 63 kilometers off the coast in the mid-deep waters of the Cuenca Salina in the Sureste Basin, offshore Mexico. The preliminary estimates suggest that the discovery holds around 300-400 million barrels of oil equivalents (Mboe) and associated gas in place. The Yopaat-1 EXP well was drilled in a water depth of 525 meters and reached a total depth of 2,931 meters, encountering approximately 200 meters of net pay of hydrocarbon-bearing sands in the Pliocene and Miocene sequences. The drilling operation was accompanied by an extensive subsurface data acquisition campaign, ensuring a comprehensive understanding of the geological formation.
