Faroe Petroleum Plc said Feb. 5 it has commenced the Fogelberg appraisal well and contingent sidetrack 6506/9 – 4A and 4S in the Norwegian North Sea (Faroe 28.3%).

Faroe announced the Fogelberg oil and gas discovery in license PL433 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.

The gross size of the discovery has been estimated to be in a range between 105 and 530 billion cubic feet (between 19 and 116 million barrels of oil equivalent including the condensate) of recoverable gas and condensate. The volumetric range is large due to the Fogelberg discovery well being located high on the structure. The main objectives of the appraisal well are to narrow this range in the reserves estimates and to provide additional information for development planning.

Fogelberg is located 11 miles (18 km) 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.

The appraisal well will be drilled with the Island Innovator semisubmersible drilling rig, and the joint-venture partners are Spirit Energy Norge AS (operator 51.7%) and PGNiG Upstream Norway AS (20%).
