Cairn Energy together with its joint venture partners is pleased to announce that the FAN-1 exploration well, offshore Senegal, has discovered oil.

The well, located in 1,427 metres (m) water depth and approximately 100 kilometres offshore in the Sangomar Deep block, has reached a Target Depth (TD) of 4,927 m and was targeting multiple stacked deepwater fans.

Preliminary analysis indicates:

◾ 29m of net oil bearing reservoir in Cretaceous sandstones ◾ No water contact was encountered in a gross oil bearing interval of more than 500m ◾ Distinct oils types ranging from 28° API up to 41° API indicated so far from a number of oil samples recovered to surface ◾ Initial gross STOIIP estimates for the FAN-1 well range from P90, 250 mmbbls, P50, 950 mmbbls to P10, 2,500 mmbbls and are broadly in line with pre-drill STOIIP estimates
