23-11-09 China National Petroleum Corp. (CNPC), China's biggest oil and gas producer, has signed agreements with Sudan to expand a refinery and swap oil production assets, according to the company.
The refinery, based in Khartoum, in which CNPC and Sudan each have equal stakes, will undergo a second expansion.

The refinery was established in 1997 and began production three years later with a designed annual processing capacity of 2.5 mm tons. It was expanded in 2006. It processes annually 5 mm tons of oil, and supplies 80 % of the refined oil in Sudan.
CNPC will partially swap a shareholding in Block 6 with Malaysia's Petroliam Nasional's Block 5A in Sudan.

The company also announced it had signed an agreement with the Sudanese government on advance payment for crude oil supplies.
CNPC has eight oil projects in Sudan, covering areas such as geophysical prospecting, well drilling, construction, and pipelines.
