Pemex, Mexico’s state oil firm, said on Tuesday it is delaying the reopening of its refinery at Salina Cruz because of numerous aftershocks following the September earthquake that caused the closure.
A spokesman said there is no date set yet for the restart of the 330,000 bpd facility, which is Pemex’s largest.
Originally the company had set the third week of October as a prospective restart date.
The 8.1 magnitude Chiapas earthquake, which struck on September 7, was the strongest in a century to hit Mexico. Its epicentre was offshore near the country’s southern Pacific coast.
Salina Cruz is in Oaxaca state, neighbouring Chiapas.
The refinery was also closed between mid-June and August this year because of fire damage that happened in the wake of flooding related to Tropical Storm Calvin.
