Cairn Energy and its partners offshore Senegal, FAR Ltd., ConocoPhillips, and Petrosen have recovered oil samples from their FAN-1 exploration well. Elevated gas and fluorescence were encountered in a shallow secondary target and the presence of oil was confirmed by an intermediate logging program.
The oil samples from a thin sand were collected by an MDT wireline formation tester for further analysis. This well data confirms the existence of a working petroleum system.
The well has reached a depth of 4,402 meters where intermediate casing has now been set. The well will be deepened to planned TD of approximately 5,000 meters. Conclusive results for this well will not be available until drilling operations are completed and all of the well data is fully assessed. Cairn anticipates that drilling of the FAN-1 well will be completed during the next month after which time the rig will be moved to the SNE-1 well location, the partners’ second well of the two-well program off the West African country.
FAR Managing Director, Cath Norman said, “The presence of oil In the secondary target is important in helping our geological understanding of the margin and is significant because it confirms the existence of a working petroleum generating system. It is very pleasing that the building blocks of a working petroleum system are present and we look forward to drilling ahead to deeper objectives in FAN-1 and completing the SNE-1 well.”
