The well is being drilled by the Borgsten Dolphin semisub in 366 feet of water. The well is a high angle well, will intersect the Upper Jurassic Ettrick sandstone reservoir target and is expected to reach a total depth of approximately 12, 240 feet MD> The well will be suspended as producer prior to being tied back to the floating production storage and offloading vessel Aoka Mizu. The well will be followed by the drilling of two further production wells and one water injection well o the field. A further oneor two development wells will be drilled later in field life dependent on field performance.
Wilhelm Petersen, Managing Director of P/F Atlantic Petroleum said:
Ettrick Field is located on Licenses P317 & P272, Blocks 20/2a and 20/3a, in the UK Central North Sea. The licenses are operated by Nexen (79.73%) with partners Bow Valley (12%) and Atlantic Petroleum (8.27%).
The field was discovered by the 20/2-1 well, drilled in 1981 by BNOC, and tested 4,358 bopd from Upper Jurassic, Middle Volgian Ettrick turbidite sandstones at 10,300 ft TVDSS and also encountered oil in the underlying Zechstein carbonates.
The field was appraised by seven further wells between 1982 and 1985, four of them successfully producing oil to surface.
The UK Department of Trade and Industry approved the development plan for Ettrick in July 2006. The development consists of a leased floating production storage and offloading vessel (FPSO), which is called the Aoka Mizu and is currently being modified in preparation for planned first oil in the first half of 2008.
