Pemex, Mexico's state-run energy firm, has announce it is still searching for three workers who went missing after Wednesday’s fire, which occurred at an offshore oil platform.

More than 300 workers were evacuated from the rig in the Gulf of Mexico. The blazed killed four.

Daily production at the rig is down because of the aftermath of the fire.

A Pemex company official said, as reported by the BBC, that the production has fallen from 650,000 barrels down to 430,000 barrels.

Pemex is currently losing close to $10 million a day.

As reported in the Washington Post, Gustavo Hernandez, the director general of exploration and production at Pemex, said, “It will be possible to reach in the next week 80 percent of the production that there was before the accident.”

Hernandez stressed the difficulty in restoring production due to the large number of pipelines which had been affected by the fire.

As reported by the BBC a survivor described how workers had jumped for safety into the sea out of what was described as “desperation and panic."

Eight firefighting boats were required to put an end to the flames.

Mexican President Enrique Peña Nieto has announced there will be an exhaustive investigation into the factors that caused the fire.

While the accident was responsible for some oil running off into the sea, Pemex has stated that a "considerable oil spill" had been avoided.

This is not the first time the Mexican state-owned petroleum company has had to deal with a large explosion.

A 1979 blowout at a Pemex well in the Campeche Sound led to what is considered one of the worst oil spills in history. Pemex took more than nine months to stop the leak. The oil lost during that time went as far as the Texas shoreline.
