Cairn Energy, the operator of the SNE field in Senegal, released a resource update on 22nd August as part of its half-year announcement.
The updated 2C resource base is 563mmbbl gross (vs. 473mmbbl in May 2016) and now brings it in line with Woodside's estimate of 560mmbbl, but is still far below that of partner FAR which carries 641mmbbl (assessed by RISC). The differing resource estimates is nothing new and we constantly see the other partners playing catch-up with FAR.
Focus is now on FEED with no further drilling planned until after FID. It is envisaged that SNE will undertake a phased development with the initial phase targeting the lower 500 series sands and core area of the upper 400 series sands. The second phase will target the remainder of the 400 series and more outreach parts of the field.
Gross capex is currently estimated at USD2.3 bn, but could come down as the engineering is defined and possibility of Woodside bringing in an existing FPSO. FID for Phase 1 is planned for the end of 2018 with first oil in 2021 and an initial plateau of 75-125mbopd.
The partners are Cairn 40%, Woodside 35%, FAR 15% and Petrosen 10% (Petrosen has the option to increase its interest to 18% during the development phase).
