Deviated appraisal well, drilled as a pilot, on the Finlaggan gas/condensate field. Combination structural/stratigraphic pinch-out trap in Britannia Sandstone at 11,340–11,945 ft TVDSS (gas-water contact). Well deviated NNW from field manifold location to confirm reservoir development and depth in Finlaggan Northeast field area. Well was batch drilled with 21/5c-F2, with top hole section drilled then re-entered to complete. Well encountered full gas/condensate column in Britannia, exceeding 250 ft TVT and was abandoned at 13,009 ft (11,942 ft TVDSS) and plugged back to drill sub-horizontal production well 21/5c-F1Z.
