Oil blocks and concession-holding companies

 

Map of oil concession blocks in South Sudan

Map: Oil concession blocks in South Sudan.

Source: Based on Geomedia and ECOS, 2007.

The Government of South Sudan has made ESPAs (exploration and production sharing agreements) with several oil companies. The primary companies are combined with others in joint operating companies (JOCs). Each JOC is provided with a concession to work in a geographical block or group of blocks.

The map on the right shows the rough location of the blocks. The table below shows the JOC that has the concession for each group of blocks, and the member companies of that JOC.

 
Blocks Productiveness Joint operating company Primary companies
1, 2, 4 An estimated 120,000 bpd of Nile Blend in 2011, but this includes the share of Sudan, as the blocks straddle the border. As of 2013/08 the border in this area is still contested, which has affected – and may well continue to affect – oil production. In any case, production here seems to be on a declining trend, down from 290,000 bpd in 2004. GPOC (Greater Pioneer Operating Company)
3, 7 An estimated 230,000 bpd of Dar Blend in 2011. DPOC (Dar Petroleum Operating Company)
5A An estimated 15,000 bpd of Nile Blend in 2011. SPOC (Sudd Petroleum Operating Company)
5B Not apparently producing. Exploration and development has been adversely affected by rebellion and violence in Jonglei. ASOC (ASCOM Sudd Operating Company)
A Not apparently producing [None: awaiting licensing]
B1, B2 Not apparently producing [?]
B3, E Not apparently producing [-]
C Not apparently producing [None: awaiting licensing]

Main Sources

For the Productiveness column, the main source is EIA, 2012/03/19.

For the company columns, the main source is the Nilepet website (accessed 2013/08/15). Under the Petroleum Act (2012) it appears that Nilepet is to be reconstituted as the National Petroleum and Gas Company. At the time of writing it is unclear how far this process has progressed, and it is here assumed that NPGC will take over Nilepet's shares in the various JOCs.

  
Questions to pursue
  • Are the ESPAs available to see? What is in them?
  • What are the relevant corporate policies (environment, labour, CSR etc) of each of the companies?
  • What are the practices of each company in publishing relevant information on the internet?
