Moray Firth / Witch Ground Graben
16 February 2017

Appraisal wells on the Finlaggan gas/condensate field, with the vertical 21/5c-7 main hole and 21/5c-7Z sidetrack, deviated 10,000 ft to the NW, testing separate fault blocks on either side of an east-west trending fault. The 21/5c-7 main hole encountered gas/condensate, but with a different gas-water contact to that seen in discovery well 21/5a-6Z, 6X, which may reflect depletion via Brodgar, The 21/5c-7Z well was located in the fault block drilled by the discovery wells. This well was tested at 40 mmcfgpd + 3,120 bcpd.
