Pemex and Petrobras Begin Joint Evaluation of 8 Offshore Assets in the Gulf of Mexico

Pemex and Petrobras have launched the first phase of a joint exploratory evaluation of deepwater and pre-salt play in the Gulf of Mexico, the Mexican oil company announced during its second-quarter 2026 earnings call on July 31. This marks the first operational step following the memorandum of understanding (MOU) signed by both state-owned companies on June 23 in Rio de Janeiro.

Pemex's Director of Exploration and Production, Octavio Barrera, stated that the technical teams of both companies are already working on the integration and analysis of geological and geophysical data, including seismic studies and well data. "It is an opportunity to accelerate learning curves, reducing technical and financial risk," he said during the analyst call, as reported by Bloomberg Línea.

The data exchange covers eight offshore assets: Anegada-Labay, Centauro, Centauro Sur, Holok-Alvarado, Magno Etapa 1 Q, Máximo, Máximo Ampliación, and Yoka-Butub. It also includes data from the mature fields Akal and Pit-Kayab-Utsil. The Ministry of Energy (SENER) is collaborating with Petrobras to facilitate the exchange of geological and geophysical information needed to build subsurface models.

Petrobras brings to the alliance its expertise in deepwater exploration, seismic processing, and prospect evaluation. The Brazilian state company produces 2.4 million barrels per day, 11 percent more than in 2025, and is a world leader in pre-salt extraction, the type of reservoir that Mexico is only beginning to characterize. Pemex produces 1.6 million barrels per day (its lowest level in four decades) and has no deepwater production. Its first project on that frontier, Trion in partnership with Woodside, will not begin until 2028.

A Citibanamex analysis published on July 29 described the agreement as positive for both parties, but cautioned that the memorandum does not commit either side to investments or create a joint venture. "Until there are binding contracts, a budget, and an execution timeline, its impact will be marginal," the bank noted.

The MOU, with a two-year renewable term, opens the door to cooperation in refining, petrochemicals, fertilizers, and carbon capture, in addition to exploration. For it to translate into investment, binding agreements, feasibility studies, and regulatory approvals from both sides will be required. The next tangible signal will be the signing of a specific contract for one of the assets under evaluation.
