Mexico’s state oil giant Pemex is struggling to reverse a years-long decline in oil and gas production while trying not to incur additional liabilities on top of its already massive pile of $100 billion debt that makes it the world’s most indebted energy firm.
Petroleos Mexicanos, as Pemex is officially known, has received major government support this year under Mexico’s President Claudia Sheinbaum.
Unlike her predecessor and mentor, Andrés Manuel López Obrador, incumbent President Sheinbaum has signaled openness to foreign firms participating in the Mexican upstream sector, although Pemex still keeps majority stakes in joint projects.
This year, Sheinbaum’s administration has launched a new contract framework for joint ventures, the so-called mixed contracts. In mixed development allocations, Pemex can enter into an agreement with one or more private firms.
Pemex has just awarded the first five of 11 planned joint venture contracts for this year, Reuters reported this week, citing sources with knowledge of the development and a document it has seen.
None of these contracts, however, were awarded to a major international firm. All five agreements for onshore development blocks were with four little known local companies—Consorcio Petrolero 5M del Golfo, Geolis, Petrolera Miahuapan, and Cesigsa, according to the document Reuters has reviewed.
These small domestic players are unlikely to move the needle in Pemex’s quest to stop production declines and cash bleeds, analysts say.
True, Pemex signed earlier this year a $1.99 billion deal with Carlos Slim’s Grupo Carso, which will drill 32 wells in three years. Australia’s Woodside Energy, which inherited the huge offshore Trion field in the Perdido Fold Belt in its merger with BHP Petroleum, has made a final investment decision to develop the resource, with first oil targeted for 2028.
Despite touting interest from some oil majors, Pemex appears to have failed to attract big international companies to the new joint venture contracts.
Under López Obrador, foreign investors backed off Mexico as the former president sought a “Mexico first” energy policy and undid most of the open-market reforms in the energy sector of his predecessor Enrique Pena Nieto that had attracted majors to the country.
Current President Sheinbaum is more open than López Obrador to foreign participation in Mexico’s upstream, but it seems that Pemex’s massive debt and failure to pay contractors and partners on time are putting off Big Oil.
“There's always the doubt about whether Pemex can honor its commitments, given that paying suppliers remains an issue,” an unnamed industry source told Reuters earlier this month. Companies with outstanding bills to be paid by Pemex include Italy’s Eni, as well as oilfield services giants SLB, Halliburton, and Baker Hughes.
The joint ventures with small domestic firms are unlikely to raise Pemex’s production much.
Oil production hasn’t seen a major bump this year. Output fell in early 2025 and grew by just 17,600 barrels per day (bpd) in the third quarter compared to the second quarter.
Pemex and Mexico target 1.8 million bpd in oil production by 2030, up from about 1.64 million bpd currently.
Pemex will need to halt the decline in oil production from mature fields and boost output from new fields to reach the 2030 target, analysts at BBVA Research said.
Government support for Pemex has also increased under President Sheinbaum, with Mexico issuing new $12-billion debt to back the state oil company.
This injection of funds has strengthened the linkage between the state and the state oil firm, supporting a higher rating for the company, Fitch Ratings said in August when it upgraded Pemex’s ratings.
However, Fitch warns that Pemex’s financial profile remains weak with persistent negative funds from operations (FFO), squeezed EBITDA due to lower crude prices and production, tight liquidity, and unrelenting losses in the downstream business.
At June 30, 2025, Pemex had as much as $98.8 billion in debt. Interest expense was $2.0 billion—more than half of the second quarter’s EBITDA. Expected leverage through the rating horizon exceeds 15x, Fitch said.
“Production and development of new fields have declined in the last few years, making exploration and production (E&P) capex a top risk,” the rating agency noted.
Big Oil appears to have also noted that risks would be greater in Mexico’s upstream than in other oil provinces competing for the majors’ capital budgets and development plans.
