Blake Appraisal Results Are In
BG Group has successfully tested two zones in the Blake Flank structure in the North Sea, with an appraisal well which spudded on September 17.
Tests at the first zone, over the Coracle Formation, flowed at a rate of 2450 barrels of oil per day on a 56/64th inch choke. The second test was designed to determine the productivity of the overlying Captain sands, and it flowed at 3000 barrels of oil per day on a 64/64th inch choke. A sidetrack to the well 13/24a-8 is now being drilled to confirm volumes within the structure. If this proves successful, BG and partners intend to fast-track the Blake Flank development.
The Blake Flank structure lies directly to the north-east of the Blake Channel structure, which was brought on stream by the Blake field owners in June 2001. BG Group is the field operator and holds a 44 percent interest, with Talisman Energy holding 53.6 percent and Paladin Resources holding the remaining 2.4 percent.
The Blake field is located 64 miles from Aberdeen in the Outer Moray Firth and started production on June 27 2001, just 18 months after project sanction. It has estimated gross field reserves of around 70 million barrels of oil, and has reached a peak flow of 60,000 barrels of oil per day.
