Operator Cairn Energy has recovered oil samples in the Fan-1 exploration well. Partner FAR said elevated gas and fluorescence had been encountered in a shallow secondary target and the presence of oil was confirmed by an intermediate logging programme. Oil samples from a thin sand were collected for further analysis. On 27 August, the well had reached a depth of 4,402 metres, and was drilling ahead to planned total depth of 5,000 metres. Cairn expects to complete the well by the end of September, then move the rig to the SNE-1 well location, the second well of a two-well programme offshore Senegal.
