FAN-1 a Success Offshore Senegal

Wednesday, October 8, 2014

Cairn Energy and its partners offshore Senegal, FAR Ltd. and ConocoPhillips, have made a discovery on the Sangomar Deep Block. The well logged 29 meters of net oil bearing reservoir in Cretaceous age sandstones with the FAN-1 well.

According to Cairn’s partner FAR, the key pre-drill well objectives were met, with preliminary well results indicating a significant resource volume. Potential net oil bearing reservoirs in addition to those included in the preliminary analysis were identified.

As intended pre-spud, there are no plans for immediate well testing. Further analysis of the oil samples, core data and wireline logs is being completed to evaluate the net oil bearing reservoirs and the possible additional pay intervals in order to assess the full potential of the resource.

Consideration is now being given to formulating a follow up appraisal and exploration program. Calibration of the FAN-1 well with the existing 3D seismic will be undertaken to fully understand the discovery, determine future plans, and optimal drilling locations.

The well was drilled in 1,427 meters water depth to a total depth of 4,927 meters and targeted a series of stacked deep water fans. The well was drilled using the semi-submersible drilling unit Cajun Express. The FAN-1 well has been drilled to TD and logged.

The rig will shortly move to complete the second well, SNE-1. This shelf-edge prospect is targeting a dual objective in 1,100 meters water depth in the Sangomar Deep block evaluating prospective resources of 600 million barrels of oil.
