Cairn Energy has completed work on the SNE-1 well in Senegal after failing to hit hydrocarbons at a lower target.
The company and its joint venture partners had previously discovered oil in the upper clastic target.
However the deeper target of Karstified and fractured Lower Crestaceous shelf carbonates returned no hydrocarbons, Cairn Energy said.
The well will now be plugged and abandoned following logging operations.
The SNE-1 well is located in 1,100 metres water depth and is 100 metres offshore in the Sangomar block, which was drilled to a total depth of 3,000 metres.
Cairn has a 40% working interest in three blocks offshore Senegal, while ConocoPhillips has a 35% working interest, FAR Ltd a 15% interest and the national company of Senegal Oil has 10%.
The three blocks cover 7,490km2.
