This will be a vertical well drilled to 5,600 ft (1,707 m) with the main aim of retrieving good-quality reservoir-condition oil samples in order to optimize the Skipper field development, based on potential resources of 341 MMbbl.
Secondary goal is to drill two mapped reservoir structures beneath Skipper in the lower Dornoch and Maureen formations, where structures have been mapped that could contain an additional 46 MMbbl. If oil is present, these structures would be co-developed with Skipper.
IOG is in negotiations with an established North Sea contractor to provide a semisubmersible to drill the Skipper appraisal well, over a 25-day period. Subject to concluding contract terms and funding, the rig is ready to mobilize at short notice.
Timing of drilling also depends on approvals for well permitting, completion of the acquisition of the remaining 50% of Skipper, and transfer of operatorship.
IOG has agreed to terms for GE Oil and Gas to provide wellheads and related equipment for this well and additional subsea kit for the planned Skipper development. Subject to UK government approval, AGR will be the well operator.
Based on flow tests from other nearby heavy-oil fields, IOG estimates a 25% recovery factor.
