PetroSA Operations in South Sudan

Petro SA signed agreement to explore S Sudan in 2005 http://www.sudantribune.com/PetroSA-to-explore-oil,7366

however

"PETRO SA said that, given the economic downturn, it had embarked on a "rigorous" cost-saving exercise, which included a portfolio rationalisation process that had seen PetroSA dispose of its interest in Sudan's Block 14 exploration acreage." http://www.engineeringnews.co.za/article/petrosa-posts-r196bn-profit-revenue-hits-record-2009-11-10

the company left partially because of security problems http://www.ecosonline.org/news/2009/Exploration_Setbacks_Compound_Sudan_problems/
