Following a period of coring and data acquisition, the well reached a vertical depth of 4,736mt below the sea surface and was terminated in the Are formation in lower Jurassic.
The aim of the well was to prove hydrocarbons in the Garn, Ile, Tofte and Tilje Formations in middle and lower Jurassic reservoirs. Gas and condensate was encountered in the Garn and Ile formations, while the fluid contacts and content within the deeper Tofte and Tilje formations remain inconclusive at this stage, although they may be water bearing, the company said.
The gross size of the discovery has been estimated to be in a range between 105 and 530 billion cubic feet (between 19 and 95 million barrels of oil equivalent) of recoverable gas and condensate of which Faroe Petroleum has a 15% net share.
The volumetric uncertainty remains relatively large at this stage due to the position of the Fogelberg well which is located relatively high on the structure. An appraisal well is likely to be needed to prove the down-dip extent and the actual size of the discovery.
Partners in the well are Centrica Resources (operator 28%), Petro-Canada, (30%) E.ON Ruhrgas (15%) and North Energy (12%).
Graham Stewart, chief executive of Faroe Petroleum, said: “We are very pleased to report the successful outcome of this exploration well. The Fogelberg well is the first of a firm five well exploration drilling program which Faroe Petroleum is participating in through 2010.
“The second well in the program, to be operated by Wintershall, is the Maria well (Faroe 30%) which is scheduled to commence drilling in the next few weeks.”
