Cairn completed operations at its SNE-1 well in offshore Senegal Wednesday but did not encounter any pay zones at the well’s secondary target.
The well struck oil at its upper clastic target but no hydrocarbons were found in the deeper target of karstified and fractured Lower Cretaceous shelf carbonates.
The well was drilled to a total depth of about 9,842 feet.
Following completion of logging operations the well will be plugged and abandoned.
Plans are now underway to appraise the discovery next year.
UK-based Cairn has a 40 percent working interest in three blocks offshore Senegal: Sangomar Deep, Sangomar Offshore and Rufisque.
The blocks cover a combined 2,891 square miles.
Texas-based ConocoPhillips has 35 percent working interest, Australia-based FAR holds a 15 percent working interest and Senegal’s Petrosen holds a 10 percent working interest.
