Eni has made a significant discovery at the Yopaat-1 EXP exploration well in Block 9, situated approximately 63 kilometers off the coast in the mid-deep waters of the Cuenca Salina in the Sureste Basin, offshore Mexico. Early estimates indicate that the site holds around 300-400 million barrels of oil equivalent (Mboe) of oil and associated gas.

The Yopaat-1 EXP well was drilled to a depth of 525 meters of water and reached a total depth of 2,931 meters. The well encountered about 200 meters of net pay in hydrocarbon-bearing sands from the Pliocene and Miocene periods. This discovery is backed by extensive subsurface data collection, offering detailed insights into the reservoir's potential.

The Block 9 joint venture includes Eni, holding a 50% interest, and Repsol, holding the remaining 50%. Combined with discoveries in Eni-operated Blocks 7 and 10, this find underscores the strategic importance of Eni's assets in the Sureste Basin.

The estimated cumulative resources now exceed 1.3 billion barrels of oil equivalent (Bboe), setting the stage for Eni to explore a potential "Hub" development. This project would incorporate the discoveries and other prospects in the area, utilizing existing infrastructure.

Eni has been active in Mexico since 2006, establishing its subsidiary Eni Mexico S. de R. L. de C.V. in 2015. Eni is currently the leading foreign operator in Mexico, with rights in eight exploration and production blocks in the Sureste Basin, seven of which it operates. This latest discovery reinforces Eni’s prominent position in Mexico’s energy sector and highlights the company’s dedication to expanding its resource base through strategic exploration and development.
