UK-based oil and gas exploration and production company Zennor Petroleum said drilling and testing operations have been completed at its operated Finlaggan field development in the UK Central North Sea.
The development project is targeting 30mmboe of gas condensate reserves from two subsea production wells tied back 20km to the Britannia platform, approximately 210km northeast of Aberdeen.
The Finlaggan production wells (F1 and F2) each flowed more than 12,000boepd, with rates being constrained by the surface facilities.
Both wells also produced at significantly higher than expected flowing well head pressures, highlighting the quality of the reservoir sections in the completed wells, Zennor said.
The Transocean semi-submersible drilling rig Paul B Loyd Junior has left the Finlaggan location and has been demobilized to Invergordon. The conclusion of these offshore works represents a key step in de-risking the Finlaggan development and delivering first production in Q4 2020 as planned, Zennor said.
Martin Rowe, Zennor’s Managing Director, said, "With the drilling and completion phase behind us we are now fully focused on the summer 2019 subsea installation program which will take us another step closer to realizing first production from Finlaggan next year.”
Zennor reported construction work on the 20km subsea pipe-in-pipe system and the electrohydraulic control umbilical is proceeding on schedule for installation in Q3 2019. The primary contractor TechnipFMC and its subcontractors are making excellent progress toward this next major project milestone, it said.
