Drilling Activity Summary


Results from the #1-FAN South exploration well were announced by Edinburgh, Scotland-based Cairn Energy Plc. At the offshore Senegal South Fan Prospect, the well encountered 31-degree-gravity oil in the Lower Cretaceous reservoir. It was drilled to 5,343 m and is in 2,175 m of water. According to Cairn, the venture was targeting dual prospects—an Upper Cretaceous, stacked, multilayer channelized turbidite fan prospect and a Lower Cretaceous base of slope turbidite fan, similar to the #1-FAN oil discovery in 2014. The #1-FAN South is being plugged and abandoned, and the rig is being moved to an area about 15 km north of discovery well #1-SNE. Cairn has estimated that SNE North has a prospective volume of more than 80 MMbbl of total resource in multiple objectives. The well will be in 900-m water depth and the projected depth is 2,800 m. Cairn also plans to complete additional testing to integrate this discovery with #1-FAN to establish the potential commerciality of the deepwater, basinal resource. Cairn is the operator of Sangomar Deep Offshore Block, SNE Field and #1-FAN South with 40% interest in partnership with Woodside Petroleum Ltd. holding 35%, FAR Ltd. with 15%, and Petrosen with 10%.
