Onshore Cabinda South

Onshore Cabinda South is located in the Lower Congo Basin, Angola. Before the civil war erupted in 1975, over 30 wells were drilled in the block. Since exploration in onshore Cabinda resumed in 2007, six fields have been discovered on the Onshore Cabinda South block: Massambala, Coco, Castanha, Sorgo, Amêndoa and NOZ. The first discovery on the block, Massambala, was made by Roc Oil in 2007. In 2009, the company made a further discovery, Coco, before handing over operatorship to Pluspetrol. The Castanha field was discovered in 2010. Following successful appraisal, the field was declared commercial in 2011 and production from the Castanha and Coco fields started in 2013. In the same year, the NOZ field was discovered and an appraisal well was drilled in 2014. The Castanha development is a landmark for Angola as it will mark the first onshore development in the Cabinda region since Angola's independence.
