It has been a busy time for PetroChina. Earlier in December it announced plans to build ten 100,000m3 oil depots for crude oil storage in Chengdu, and on 8 December it began trial crude oil storage operations in the southern Guangxi region.
The ramp-up forms part of China's efforts to build up oil stockpiles to improve ability to cope with any potential supply shocks.
The 42 crude oil tanks, each with capacity of 100,000m3, were a portion of PetroChina's first phase of 10 million m3 of storage tanks in a bonded area in Qinzhou.
PetroChina has stored 520,000 tonnes or some 3.8 million barrels of west African crude in some of the tanks and started bonded business there.
The Chinese crude oil and gas producer has planned another 10 million m3 of crude storage in Qinzhou as a second phase.
