Exploration and appraisal
From 2000 to 2010, ROC actively explored several operated Perth Basin exploration permits, acquiring 5,800km 2D and 1,289km2 3D seismic and drilling eleven exploration wells (the first of which discovered the Cliff Head Oil Field). Four appraisal wells were drilled on the field, before commencing development. Two discoveries made in 2007 in WA-286-P, Frankland-1 and Dunsborough-1 (a gas discovery and a light oil / gas discovery, respectively) were appraised with a well each in 2008.
In this time, ROC also explored one non-operated Carnarvon permit (WA-351-P), participating in the drilling of one exploration well and the acquisition of 3,493km2 3D seismic.
ROC has subsequently surrendered or sold all Western Australian exploration permits.
Additional reserves potential on the western flank of the Cliff Head Oil Field in WA-31-L is being assessed based on revised seismic interpretation and depth mapping.
Development and production
ROC currently operates one production license in offshore Western Australia covering the Cliff Head Oil Field. Development activity was completed in July 2006 and production commenced 1 May 2006.
ROC has a strategic 0.25% interest in the producing Jingemia Oil Field, onshore Perth Basin, operated by Origin Energy.
