Cairn and its Joint Venture (JV) partners have completed operations on the SNE-1 well in Senegal and plans are now underway to appraise the discovery next year.
Having discovered oil in the upper clastic target, no hydrocarbons were subsequently encountered in the deeper target of karstified and fractured Lower Cretaceous shelf carbonates. Following completion of logging operations the well will be plugged and abandoned, Cairn said.
The SNE-1 well located in 1,100 metres water depth and approximately 100 kilometres offshore in the Sangomar Offshore block was drilled to a total depth of ~3,000m.
Cairn has a 40% Working Interest in three blocks offshore Senegal (Sangomar Deep, Sangomar Offshore and Rufisque), ConocoPhillips has 35%, FAR Ltd 15% and Petrosen, the national oil company of Senegal 10%.
The three blocks cover 7,490 km2.
