Exploratory drilling by Pemex, Mexico’s state-owned oil giant, has fallen to its lowest level in nearly three decades, according to data cited by Rio Times.
The sharp decline in early 2026 marks a significant contraction in the company’s efforts to replace depleting reserves, even as its balance sheet shows signs of improvement.
The drop in exploration activity presents a long-term structural risk for Mexico’s energy sector.
While Pemex has managed to stabilize its finances in recent quarters, the lack of new reserve replacements threatens future production capacity.
Investors are increasingly focused on the sustainability of the company’s output, with the current drilling pace suggesting a potential bottleneck in supply growth over the coming years.
This development adds to broader concerns about investment levels in emerging market oil producers.
