Angola: ROC's Castanha-1 well in the Cabinda Onshore South Block tests oil

08 Feb 2010

Lacula Oil Company, a wholly owned subsidiary of ROC, provides an update on activity at the Cabinda Onshore South Block, Angola. The Castanha-1 exploration well that commenced drilling on 13 November 2009 has reached Total Depth of 3,400 mBRT. The well encountered a gross hydrocarbon column of approx. 15 metres (between 2,214 mBRT and 2,229 mBRT) in the pre-salt section. Wireline testing recovered oil (estimated to be approx. 33° API) from this interval and preparations are under way to production test the well.

The Coco-1 extended well test that commenced in November 2009 has been completed and the well suspended. Results indicate that none of the five zones tested exhibited natural hydrocarbon flow. The testing equipment has been re-directed to the Castanha-1 exploration well. Depending on the success of the planned production testing at Castanha-1, Joint Venture participants will review the results from the Coco-1 extended well test and its future potential.

Participating Interests in the Cabinda Onshore South Block are: Pluspetrol Angola Corporation (Operator) 45%; Force Petroleum de Angola 20%; Sonangol P&P 20%; Lacula Oil Company 10%; Cuba Petroleo 5%.
