Cairn Energy has completed testing of the SNE-2 appraisal well offshore Senegal with positive results. Operations have been safely and successfully completed following drilling, coring, logging and drill-stem testing (DST). The well is now being plugged and abandoned.
Following this first successful appraisal well, resource estimates for the SNE field will be fully revised and announced after the results of the further appraisal activity. Evaluation of the extensive dataset collected is continuing, with preliminary analysis focused on the DST:
DST over a 12 metre (m) interval of high quality pay flowed at a maximum stabilised, but constrained rate of ~8,000bopd on a 48/64' choke, confirming the high deliverability of the principal reservoir unit in the SNE-2 well
DST over a 15m interval (~3.5m net) of relatively low quality 'heterolithic' pay flowed at a maximum rate
of ~1,000 bopd on a 24/64' choke, confirming that these reservoirs are able to produce at viable rates
and thus make a material contribution to resource volumes. Flow was unstable due to the 4.5' DST tubing
Multiple samples of oil and gas recovered to surface from wireline logs and drill stem tests
Confirmation of correlation of the principle reservoir units between SNE-1 and SNE-2 with the primary reservoirs occurring in the gas cap as predicted.
