Licence P2013 contains the Finlaggan gas condensate accumulation originally drilled by ConocoPhilips in 2005. As Operator Zennor drilled an appraisal well (21/5c-7) and side-track (21/5c-7Z) with the Transocean Sedco 704 semi-submersible rig in Q2 2016. The side-track drill stem tested at a surface equipment constrained stable rate of 9,875 boepd (40 mmscfd of gas and 3,120 bbls/d of condensate).
In 2017 Zennor selected Britannia as the offtake route for Finlaggan. The project FID decision followed in 2018, with commencement of drilling operations in July 2018 and a formal Field Development Plan approval by the OGA on 18th October 2018. Finlaggan will be developed by a 2-well subsea tie back to Britannia through a pipe-in-pipe subsea system controlled via an electrohydraulic umbilical.
The majority of the subsea installation work is expected to occur in 2019 with first gas scheduled for Q4 2020 after the final tie-ins are completed during the tri-annual Britannia shutdown.
