Citgo Petroleum, a subsidiary of state-run oil holding Petróleos de Venezuela (Pdvsa) based in the United States, reported that on Tuesday morning there was a minor fire in its refinery at Corpus Christi, Texas. The fire was extinguished at once.

The refinery has the capacity to process 165,000 bpd, Reuters reported.

"There were no injuries," spokesman David McCollum said.

As stated by operators, the reformer of 30,000 bpd came to a standstill and was to restart operations soon. A cut in the output of the hydrogenation unit reduced the supply both for the hydro-treater and the diesel plant.
