SANTIAGO, Aug 25 (Reuters) - Chile's Aconcagua oil refinery has made progress in returning to normal operations since it was partially halted following an earthquake and is expected to be running normally in the next few days, a source at state-run oil firm ENAP said on Monday.
"The process of normalization at the plants, which began yesterday, is about 80 percent complete, and in the next few days they are expected to be 100 percent operational," the source said.
ENAP stopped some operations as a security measure on Saturday following a 6.4 magnitude quake in central Chile. There were no injuries or infrastructure damage, it said.
Chile has two major oil refineries, Aconcagua and Bio-Bio, both run by ENAP. Bio-Bio has continued to operate normally, ENAP said. (Reporting by Antonio de la Jara; Writing by Rosalba O'Brien; Editing by Paul Simao)
