Cairn Energy and its joint venture (JV) partners have completed operations on the SNE-1 well, offshore Senegal.
The SNE-1 well, which is about 100km offshore in the Sangomar Offshore block, was drilled to a total depth of 3,000m.
Current plans are to evaluate the discovery in 2015.
The well, which is located in a water depth of 1,100m, near the company’s FAN-1 well, could hold between 150 million barrels and 670 million barrels of recoverable resources.
The JV partners discovered oil in the upper clastic target, but no hydrocarbons were encountered in the deeper target of karstified and fractured Lower Cretaceous shelf carbonates.
Cairn Energy is the operator and 40% owner of three blocks off the coast of Senegal, covering 7,490km².
ConocoPhillips, FAR and the national oil company of Senegal, WI and Petrosen, own 35%, 15% and 10% stakes respectively.
Earlier this year, Cairn Energy and its partners discovered oil at the FAN-1exploration well, situated about 60 miles offshore Senegal.
Located in the Sangomar Deep block, the FAN-1 well was drilled to a total depth of 16,164ft in about 4,700ft of water.
Cairn Energy, which explores oil and gas in several locations worldwide, is presently focused on three geographic regions that include the Atlantic Margin, the Mediterranean and the UK and Norway.
