Following the December 17 announcement, Petróleos Mexicanos signed its first five mixed contracts on December 19, targeting modest boosts to oil and gas output. Expected to contribute 2% of national hydrocarbons from 2028-2030, they test a model for attracting larger future investments amid Pemex's challenges.
Pemex signed the five mixed contracts previously awarded to domestic firms: Tamaulipas Construcciones (with C5M), Cuervito (Geolis), Tupilco Terciario (CECIGSA), Sini-Caparroso (C5M), and Agua Fría (Petrolera Miahuapan). Pemex sought partners for 21 areas but secured only these, some facing financial allegations.
Per Pemex's strategic plan, the fields could peak at 40,000 barrels per day—2.2% of President Claudia Sheinbaum's 1.8 million bpd target—providing about 2% of national liquid hydrocarbon production from 2028-2030.
Journalist Jeanette Leyva notes the limited immediate impact but highlights the contracts' role in validating the government-backed model for scaling to bigger projects. They could refine terms to draw technically advanced firms like Shell or Exxon, countering declines in mature fields and supporting Pemex's indebted position.
