On 8th February, FAR Ltd announced an updated independent resource report (by RISC) of the SNE discovery offshore Senegal (Cairn 40%, ConocoPhillips 35%, FAR 15% and Petrosen 10%). The report increases contingent resources for the discovery to 240mmbbl 1C (from 150mmbbl), 468mmbbl 2C (from 330mmbbl) and 940mmbbl (from 670mmbbl). This assessment includes the SNE-1 discovery well and subsequently reprocessed (more accurate) 3D seismic. Significantly the update does not include the successful SNE-2 appraisal well. Given the lack of major oil discoveries worldwide, SNE is an important find (largest since 2014) and on further positive appraisal drilling, will be an increasingly desirable asset.
Cairn previously indicated that around 200mmbbl is the commercial threshold to underpin a 'foundation' development offshore Senegal, where fiscal terms would yield a 20% IRR at USD45-50/bbl oil price. The resource report would imply that the discovery now has the scale to support a development and the SNE-2 appraisal well demonstrates deliverability following strong production tests (8,000bbl/d from blocky sands and 1,000bbl/d from hetrolithics). The next element of the appraisal campaign is to test for connectivity and the upcoming drilling should help to determine this. Significant further drilling needs to be completed; however results to date are encouraging.
The second appraisal well SNE-3 has now been cored and logged with production test results expected later in February. This will be followed by the Bellatrix exploration well testing a 168mmbbls P50 prospect, then deepening to test the northern extent of SNE (no production test planned). In addition to a more comprehensive resource update in mid-2016, there is the option for three further wells later this year. With drilling time currently ahead of expectations, there is scope to drill an additional well without extending timeline or budget.
