2010 Drilling Activity
Development drilling continues at Zhao Dong China in 2010. Parallel drilling operations from the C4 and Zhao Dong platforms are being carried out to accelerate the proposed program of 24 wells and deliver earlier production. The exploration program in Angola which commenced at the end of 2009 was completed in 1Q 2010. A Castanha appraisal well in Angola commenced drilling on 28 July 2010. The Tuatara-1 exploration well, in the newly acquired New Zealand permit operated by AWE, was plugged and abandoned in August 2010. Potential exploration drilling programs in Mauritania, Equatorial Guinea and Australia are being assessed.
2009 Drilling Activity
ROC's drilling programme for 2009 included 18 development wells in China and Australia and the commencement of an exploration programme in Angola, as summarised in the following table:
