A well drilled offshore Senegal by a group led by Cairn Energy PLC will be plugged and abandoned following completion of logging operations, and will be appraised next year.
Cairn and its joint-venture partners completed operations on the SNE-1 well, which was drilled to a total depth of 3,000 m in 1,100 m of water 100 km offshore on the Sangomar Offshore block. The well discovered oil in the Upper Clastic target but did not find hydrocarbons in the deeper target of Karstified and fractured Lower Cretaceous shelf carbonates.
Cairn has a 40% working interest in three blocks offshore Senegal—Sangomar Deep, Sangomar Offshore, and Rufisque—which cover 7,490 sq km.
Last month Cairn reported making an oil discovery with the FAN-1 exploration well on the Sangomar Deep block (OGJ Online, Oct. 7, 2014).
Cairn’s partners in the three blocks are ConocoPhillips 35%, FAR Ltd. 15%, and Senegal state oil concern Petrosen 10%.
