Petróleos Mexicanos carries out critical cleaning and sealing maneuvers after a loss of tightness in the Concepción-134 well that affected the Mezcalapa lagoon. Current technical protocols rule out imminent dangers for residents, prioritizing environmental restoration and permanent monitoring of the corroded infrastructure south of Veracruz.

Technical response to the emergency in the Mezcalapa lagoon
Petróleos Mexicanos’ operations are currently focused on the control, monitoring and containment of hydrocarbons in the town of Concepción, Minatitlán. The incident originated from a failure in the integrity of the Concepción-134 well, leading to a spill of crude oil into the Mezcalapa lagoon. Despite the visual magnitude of the event, risk assessments confirm that the safety of the civilian population is not compromised, maintaining a deployment of specialized personnel to mitigate the impact on the local ecosystem.
Chronology of the incident and preventive actions of technical personnel
The detection of hydrocarbon in the body of water was initially reported by residents of the area on April 16. The municipal agent of the community, Samuel López González, pointed out that the alarm among the residents responds to the recurrence of these events in the region. However, the work to remove contaminating material began in advance of the official notification, establishing a containment perimeter to prevent the dispersion of the crude oil.
- Well status: The Concepción-134 infrastructure has remained inactive since April 2003.
- Root cause: The lack of internal pressure stopped its commercial exploitation, but corrosion processes in the surface components have compromised its sealing.
- Previous interventions: On March 8, the first technical inspections were carried out after anomalies were detected.
Reinforcement of infrastructure and security protocols
Corrective measures applied by the engineering team include the strategic installation of clips with neoprene gaskets. These mechanisms seek to restore the airtightness of the head mechanically. Additionally, constant measurements of explosive atmospheres are carried out to prevent larger scale incidents during repair maneuvers.
Although initial testing showed positive results, additional leak events were documented on March 11 and April 1. Each episode required a reinforcement of the control systems at the wellhead, managing to stabilize operational safety conditions in each direct intervention.
Commitment to restoration and permanent surveillance
The current strategy of the state company is divided into two fundamental axes:
- Definitive assurance: Field engineering is working on a permanent solution that eliminates the possibility of new leaks resulting from metal deterioration.
- Environmental sanitation: Active crews remain active for the total cleaning of the affected areas in the Mezcalapa lagoon, seeking to return the environment to its natural state.
Continuous surveillance is the pillar of the operation in Minatitlán. Technical safety protocols are applied under international incident management standards, guaranteeing that each phase of the restoration meets the necessary protection levels for the environment and surrounding communities.
