Fogelberg development due off Norway

Spirit Energy Norge and partners plan to develop the Fogelberg gas and condensate discovery in the Norwegian Sea via subsea completion and tie-back to the B platform on Asgard field.

Spirit Energy Norge and partners plan to develop the Fogelberg gas and condensate discovery in the Norwegian Sea via subsea completion and tie-back to the B platform on Asgard field (OGJ Online, Sept. 5, 2017).

The development decision followed a drillstem test of the sidetracked 6506/9-4 A appraisal well.

Partner Faroe Petroleum said the sidetrack penetrated 58 m of gross hydrocarbon-bearing Middle Jurassic Garn sandstone and 87 m of gross pay in the Ile formation of the same age.

The well flowed at a maximum constrained and stable rate of 21 MMscfd of gas and 547 b/d of condensate through a 22/64-in. choke for 24 hr with no sign of depletion.

The sidetrack bottomed at 4,497 m TD 0.8 km from the initial wellbore and 1.7 from the 6506/9-2 S discovery well.

Fogelberg is 18 km north of the Asgard complex.

According to the Norwegian Petroleum Directorate, a downdip appraisal well, 6506/9-4 S, encountered a gas column of about 60 m in Garn with poor to moderate reservoir quality and 70 m of sandstone with poor or no quality and high water saturation in the underlying Ile.

The Island Innovator semisubmersible rig drilled the wells in about 300 m of water.
