Pemex

Petróleos Mexicanos, or Pemex, is Mexico’s state-owned petroleum company. It operates across oil and gas exploration, production, refining, transport, and sales.

Cantarell Field: A major offshore oil field in the Bay of Campeche that became Mexico’s largest producing field. Its production surge made Cantarell central to Pemex’s rise as a major oil exporter.
Mexican oil expropriation: The 1938 nationalization of foreign-owned oil assets by Mexican president Lázaro Cárdenas. It created the political and legal foundation for Pemex.
Petróleos Mexicanos Workers' Union: The labor union representing many employees of Mexico’s state petroleum company. Its collective bargaining and political influence have affected Pemex’s workforce and governance.
Petróleos Mexicanos: The formal Spanish name of Mexico’s state-owned petroleum company, commonly known as Pemex. The expanded name distinguishes the company’s legal identity from its familiar abbreviation.
Ku-Maloob-Zaap: An offshore oil complex in the Bay of Campeche and one of Mexico’s largest producing areas. Its output helped offset declining production at Cantarell.

Petrobras: Brazil’s partially state-owned, publicly traded oil and gas company. Its mixed ownership offers a regional comparison with Pemex’s state-owned structure.
Salina Cruz Refinery: A large Pemex refinery on Mexico’s Pacific coast in Oaxaca. It shows how Pemex converts crude into fuels at a major coastal processing site.
