On 17 February, opposition troops drove government forces out of the Upper Nile state capital Malakal, about 500km north of Juba near the border with Sudan. Malakal is less than 150km from major oil production facilities in the state, but output is continuing as normal, says the government. The main Upper Nile oil concession - Blocks 3 and 7 in the Melut Basin – is operated by Dar Petroleum Operating Company (DPOC), and includes the important fields of Adar, Yale, Fal and Paloich.
