Tullow Oil said its Dahoma-1 exploration well in the West Cape Three Points licence only encountered water bearing reservoirs. Angus McCoss, Exploration Director, said: "Dahoma-1 is the first of 12 wells in our deepwater Ghana Exploration and Appraisal campaign not to encounter hydrocarbons." "It was a high-risk well required to evaluate the upside potential of the area by exploring a long way down-dip from known oil. We now look forward to incorporating the data from this well and to pursuing the largely independent and considerable remaining prospectivity in the West Cape Three Points block which we will be drilling through 2010."The well was drilled 11 kilometres south of Mahogany-3 to explore a down-dip satellite prospect within the southeast Jubilee area, outside of the main Jubilee Unit Area.
