Faroe Petroleum Norge AS has completed drilling two appraisal wells intended to delineate the southern part of the 31/7-1 Brasse oil and gas discovery in 2016 (OGJ Online, June 16, 2016; July 11, 2016).
Faroe and the Norwegian Petroleum Directorate said tie-backs to existing systems in Oseberg or Brage fields are being considered. Brasse is 13 km south of Brage and 13 km southeast of Oseberg.
The wells were drilled in production license 740 by Odfjell Drilling’s Deepsea Bergen semisubmersible drilling rig in 120 m of water.
The 31/7-2 S well encountered a 9-m oil column and the 31/7-2 A sidetrack well encountered an 18-m oil column and a 4-m gas column.
NPD said a formation test for 31/7-2 S resulted in a maximum production rate of 981 cu m/day of oil.
The 31/7-2 S was drilled to 2,424 m subsea and terminated in the Tarbert formation in the Middle Jurassic. The 31/7-2 A sidetrack was drilled to a measured depth of 2,723 m and a vertical depth of 2,275 m subsea and terminated in the Sognefjord formation in the Upper Jurassic.
Size of the Brasse discovery is now estimated at a maximum 14.6 million cu m of recoverable oil equivalent, up from 12.7 million cu m.
Faroe said a preliminary reservoir development plan includes up to six production wells and an optional water injection well for pressure support. Submission of a plan for development and operation is expected in 2018.
Faroe has 50% as does Point Resources.
