Zagato appraisal well in Barents Sea confirms case for tieback to Goliat platform
Vår Energi says a newly completed appraisal well on the Goliat Ridge's Zagato oil discovery in the Barents Sea has led to an increase in estimated recoverable volumes.
The COSLProspector semisubmersible rig drilled well 7122/8-3 A, the 14th on production license 229, in 410 m of water. Early analysis from the Norwegian Offshore Directorate suggested a recoverable reserves range of 21 MMboe to 75 MMboe.
The well, positioned 7 km northeast of the Vår Energi-operated Goliat Field, penetrated multiple oil columns totaling 63 m in the Kobbe Formation.
Reservoir and oil quality appears to be similar to conditions at the producing Goliat Field.
During testing, two intervals each delivered maximum flow rates of more than 4,000 bbl/d.
Vår Energi and partner Equinor have now drilled five wells and one sidetrack in the area. Including the latest well, the Goliat Ridge contains an overall recoverable resource of 35 MMboe to 138 MMboe, with further prospective resources potentially lifting the combined gross above 200 MMboe.
The partners plan a tieback development to the Goliat FPSO and are targeting first production in 2019.
Earlier this week, Vår Energi secured a new license adjacent to the Goliat Field under Norway’s 2025 Awards in Predefined Areas (APA) licensing round. The company sees additional prospectivity on trend with the Goliat Ridge discoveries.
