Faroe was awarded this licence in 2007, as one of its first Norwegian licences and the Fogelberg oil and gas discovery was announced in April 2010. The 6506/9-2 S well encountered gas and condensate in the Middle Jurassic Garn and Ile formations and no fluid contacts were observed.
In April 2018, it was announced that an appraisal well (6506/9-4 S) had been drilled to a total depth of 4,738 metres; targeting the gas and condensate bearing Middle Jurassic Garn and Ile formations in order to assess the lateral and down-dip extent of the discovery and firm up the resource range. The appraisal well successfully penetrated the Garn and Ile formations, encountering 62.5 metres of gross hydrocarbon-bearing Garn reservoir. Gas was also logged in the Ile Formation.
A successful side-track well (6506/9-4 A) and production test (DST) followed the appraisal well. The sidetrack well penetrated 58 metres of gross hydrocarbon-bearing Garn sand-rich reservoir and 87 metres of gross hydrocarbon-bearing Ile reservoir. During the DST, the well flowed at a maximum constrained and stable rate of 21 mmscf per day and condensate at 547 bpd (aggregate 4,047 boepd) on choke 22/64” for 24 hours with no signs of depletion. Fluid sampling on the rig during the DST confirmed both high quality gas and condensate and a condensate yield in the expected range. The fluid samples will also be used to refine the design basis for the planned subsea tie-back to Åsgard B.
An update on the volumetrics will be provided after the newly acquired data has been fully interpreted and incorporated into an updated Fogelberg reservoir model. However, preliminary analysis suggests a resource range of 40-90 mmboe gross.
Development planning studies for the Fogelberg subsea tie-back to the Åsgard B host are expected to start in H2 2018 It is envisaged that Fogelberg will be developed with 2-3 horizontal gas producers from a 4 slot subsea template and tied back to the Åsgard B gas processing facilities. Gas capacity in the Åsgard transportation system was secured back in 2014 when Åsgard B was selected as a tie back host and passing DG2.
Fogelberg is located 18 kilometres north west of the producing Åsgard complex where large quantities of gas and condensate have been and continue to be produced and transported to several landing points on the European continent.
