FAR is partnering with Cairn Energy and ConocoPhillips for two deepwater wells which are part of a multi-well exploration campaign being carried out by Transocean’s fifth-generation semisubmersible Cajun Express.

Cairn is operating the drilling programme, with the second well in the multi-well campaign already underway, to be followed by the two wells in Senegal’s deep waters. Together these two wells will target up to 1.5 Bbbl of oil, testing a 900 MMbbl deepwater fan play and a 600 MMbbl shelf play.

Overall FAR estimates its Senegalese blocks Rufisque, Sangomar and Sangomar Deep, which encompass 7,490 sq km (2,891 sq miles), contain 3.585 Bbbl of prospective oil reserves.

After previous farm-in deals, which saw FAR transfer operatorship of the Senegalese blocks to Cairn in August last year, FAR now holds 15% in the blocks, Cairn 40%, ConocoPhillips 35% and state company Petrosen retains 10%.
