PARAGUANA, Venezuela, March 12 (Reuters) - Venezuela's 645,000 barrel-per-day Amuay refinery has resumed operations after a vapor problem on Tuesday and is currently operating at 370,000 bpd, workers said on Thursday.
The 64,000 bpd flexicoker at the OPEC country's biggest refinery, however, is still down, workers added.
State oil company PDVSA declined to comment. (Reporting by Sailu Urribarri; Writing by Alexandra Ulmer; Editing by Chizu Nomiyama and Franklin Paul)
