PARAGUANA, Nov 5 (Reuters) - Venezuela's Amuay oil refinery will need at least 48 hours to return to full operations after a blackout shut down the complex on Tuesday night, workers said on Wednesday.
Officials say electricity supply has been re-established at the country's biggest oil refinery and that operations are gradually starting up again.
