Pemex and Block 7 Consortium sign Pre-Unitization Agreement

MEXICO CITY, Sept. 21, 2018 /PRNewswire/ -- Petróleos Mexicanos (Pemex) and Talos Energy (NYSE:TALO), as operator of the Block 7 Consortium, are pleased to announce that Pemex and the international Block 7 Consortium (Talos Energy, Sierra Oil and Gas, and Premier Oil) have signed a Pre-Unitization Agreement (PUA) related to certain tracts within the Amoca-Yaxche-03 allocation (assigned to Pemex as part of Round 0) and the contiguous Block 7 production sharing contract (assigned to the consortium by the National Hydrocarbons Commission as part of the first tender of Round 1). Both areas are situated in the offshore portion of Mexico's prolific Southeast Basin.

This is the first Pre-Unitization Agreement ever to be signed in Mexico. Under the country's recently revamped legal and regulatory framework, this two-year agreement enables information sharing related to the recently announced Zama discovery and its potential extension into Pemex's neighboring block. It also sets a clear path for the signing of a Unit Agreement and Unit Operating Agreement in the event a shared reservoir is confirmed, as it establishes a defined process based on international practices to determine the resulting participation of each party in the potential overall development.

As a result of the agreement, both parties will immediately form a Working Group, with the objectives of maximizing operational and informational efficiencies, defining activities on each tract that optimize the collection of data in the area, and reducing any potential hazards, all to maximize the benefits for México. The Working Group will be comprised by legal and technical representatives from the member companies.

The PUA has previously been approved by the Ministry of Energy (SENER).
