Until now, the CNH has carried out two bidding rounds, in which it has executed three tenders for shallow waters (1.1, 1.2 and 2.1); two for deep waters (1.4 and 2.4); four for onshore fields (1.3, 2.2, 2.3 and 2.5); one for onshore unconventional resources (2.5); and five farm-outs for PEMEX in different fields (Trion, Ayin-Batsil, Cárdenas Mora, Ogarrio and Nobilis-Maximino).

Each tender, as well as the location of its blocks, represents a challenge of different magnitude for the operators who won each of the contracts. Therefore, CNH, being the only regulator in Mexico with the authority to execute these tenders, has to adapt the logic of its regulations to the reality of each of the blocks tendered, which in the end makes possible to have notable successes such as the Amoca field, operated by ENI International, and the Zama field, operated by Talos Energy in consortium with Sierra Oil & Gas and Premier Oil.
