An investigative report by Código Magenta has exposed a monumental escalation in Mexico’s illicit fuel trade (huachicol), revealing the existence of a high-tech, clandestine oil refinery operating openly in the state of Nuevo León. Far exceeding traditional pipeline siphoning, this illegal enterprise processes stolen crude oil directly under the alleged gaze—and complicity—of municipal, state, and federal authorities.
Located in Cadereyta Jiménez, less than 10 kilometers from an official Pemex refinery, the covert facility is hidden behind the facade of a legitimate towing and mechanical business called Servicios y Grúas Flores. According to industrial experts and intelligence reports obtained by journalists Ramón Alberto Garza and Rodrigo Carbajal, the facility boasts professional-grade infrastructure. It utilizes interconnected steel pipelines and massive 5,000-barrel “frac-tanks” configured to feed crude via gravity, a method that strategically avoids the sound and energy signatures of mechanical pumps.
The “huachi-refinery” reportedly processes between 5,000 and 10,000 barrels of stolen crude and naphtha daily. The resulting low-cost gasoline and diesel are seamlessly funneled into a black-market network of complicit service stations. The multi-million dollar profits are allegedly laundered through prominent politically connected tax firms and reinvested into high-end real estate across Mexico.
The revelation follows a massive May 29, 2026, raid by Mexico’s Attorney General’s Office (FGR) and the military (SEDENA), which seized over one million liters of illicit fuel just kilometers away from the site. That operation targeted the criminal network of Joaquín Arzate, alias “El Chimuelo.”
Despite the staggering size of the newly exposed refinery and the steady convoy of fuel tankers entering and leaving the property, security forces like the National Guard and state police have notably failed to intervene, highlighting deep-seated systemic corruption in the region.
