16 May 2014, News Wires – Scotland’s Cairn Energy has moved back to its first well at the current drilling campaign offshore Senegal to drill deeper into the prospect.
Cairn started drilling Fan-1 earlier this year using the semi-submersible drilling rig Cajun Express.
The well is located on the North Fan prospect at the Sangomar Deep Block.
Fan-1 is targeting multiple stacked deepwater fans, which have been assessed as potentially think, high-quality clastic reservoirs.
The rig moved onto the second exploration well Sne-1 on the Shelf Edge prospect, but has now returned to the Fan-1 location to continue drilling deeper, according to Australian joint venture partner Far.
Cairn has a 40% working interest in the three blocks offshore Senegal and is working with joint venture partners ConocoPhillips (35%), Far (15%) and Petrosen (10%).
If there is commercial success, ConocoPhillips will have the option to operate the development of a potential resource.
Fan-1 is testing a structure with the potential to hold about 900 million barrels of oil.
Together with the second exploration well, the joint venture partners will be targeting about 1.5 billion barrels of oil.
Drilling of the well is expected to be finished by the end of June.
