LONDON – IOG is still aiming for first gas before year-end from the Blythe and Elgood fields in the UK southern North Sea (Saturn Banks project Phase 1).
Work has finished on the subsea and hookup scopes and IOG is assisting Perenco, operator of the gas terminal at Bacton on the Norfolk coast to complete commissioning of the reception facilities.
Recently completed items include a newly installed 24-in. emergency shutdown valve, pipeline spools and motorized valves; replacement of the gas metering streams and associated isolation valves; and installation of new pressure control valves and pulling/terminating of all multi-core cables.
IOG, Perenco UK, and the onshore contractors are also working to speed up completion of intra-terminal pipework, testing of telecoms and control systems, and installation of the emergency vent stack.
Once the onshore scope has finished, along with final systems testing, nitrogen venting and backgassing of the pipelines should allow the Blythe and Elgood wells to start up in quick succession.
The jackup Noble Hans Deul is preparing to re-mobilize to the Southwark field in early December once it has been re-certified for safe operation. This follows an investigation of structural issues which led to the rig being taken off-station and transferred to the port of Dundee in Scotland for leg repairs, entailing mobilization of equipment and personnel from the Middle East and Asia.
Planning and contracting continues for appraisal wells next year at Kelham North / Kelham Central (P2442: block 53/1b) and Goddard (P2342: block 48/11c and 12b), which the Noble Hans Deul will drill after the second Southwark well. Petrofac will operate both wells.
In parallel, analysis of reservoir and production data from the Southwark 1 and 2 wells will support planning for the Southwark 3 well.
Finally, IOG is progressing concept select work for the Nailsworth project, targeting FID early next year, while seismic reprocessing work is about to start for license P2589 (Panther / Grafton area). The results should provide an enhanced subsurface view of the area directly east of Southwark and Elland.
