4. CEO’s Comments
Commenting on the commencement of the three new wells, ROC’s Chief Executive Officer, John Doran stated that:
“ROC is going through a period of record exploration and appraisal drilling activity. Four wells in four countries simultaneously testing targets in shallow water offshore China and Western Australia, deepwater offshore Mauritania and onshore Angola. The perceived risks range from high frontier exploration to lower risk appraisal while the size of the individual features being tested ranges up to hundreds of millions of barrels of recoverable oil. Three of the four wells are operated by ROC, the exception being the well in Mauritania. When these four wells are finished and regardless of their results, ROC’s 2008 exploration and appraisal drilling programme will simply roll on to the next set of wells offshore China and Mauritania and onshore Angola, thereby ensuring shareholders remain exposed to potentially important drilling results through to the middle of the year and beyond.”
