China's CNPC said it has lost more than $250 million since the earthquake.

China National Petroleum Corp., PetroChina's parent firm, said Monday it has suffered $254.9 million in direct economic losses from the Sichuan earthquake last week.

About 908 PetroChina gas stations were at least partially damaged, and 65 had to be closed because of severe damage.

While the majority of fuel services have been restored, according to officials, the losses were substantial, China Daily reported.

CNPC's oil and gas fields, refining plants and oil pipeline in the Sichuan, Shaanxi and Gansu provinces were affected. Five employees were killed and 44 others injured. Ten others remain missing.
