Endeavour readies for Rubie II

Endeavour Energy has filed an environmental impact statement covering the Rubie II development in the UK sector of the North Sea.

Planning for the project involves a further production well to develop the Rubie field in block 15/28b covered by licence P226 which is to be tied back to the existing Renie subsea manifold via an 8-inch subsea flowline and from there to the Hess-operated AH001 semi-submersible floating production facility 22 km (13.75 miles) distant.
.
Project scheduling indicates drilling of the new development well will commence in the fourth quarter this year, probably November, and will take 60 days to drill, test and complete, with the Transocean’s Sedco 704 semi-submersible, followed by subsea installation and commissioning work in the second quarter 2009.

Topsides modifications on the AH001 are due to take place in March 2009, and pipeline and umbilical installation are scheduled for April, and first oil should be produced by the second quarter also, with the target next May.

Rubie lies 7 km (4.3 miles) east of the Renee manifold and one well is already producing from the field. The new second well is to be drilled into the Rubie Sele reservoir and tied back via the Rubie manifold to AH001, with a 3-inch gas lift and umbilical line. Also topsides modifications on the Hess production facility will be required, involving changes to the gas compression system plus electrical and hydraulic power units and master control station.

Oil will be exported from AH001 via Claymore and the Flotta pipeline to the UK Flotta terminal.

Endeavour indicates that the maximum possible oil recovery from the development is 7 m bbl oil, with daily production forecast at 10,000 b/d.

Endeavour indicates that the Rubie II well could produce for 16 years from 2009 to 2025 with a decline after the first five months of output

Endeavour operates the project with 40.87% and its partners are Hess Limited with 19.22%), and Marubeni Oil and Gas UK Ltd with 40%.
