20/05/2009 Press Release 27/2009 StatoilHydro Petroleum AS, operator of production licence 035 B, has finished the drilling of appraisal well 30/11-7 A on the gas/condensate discovery 30/11-7, which was proven during the winter of 2009. The discovery was made in Middle Jurassic reservoir rocks (lower parts of the Brent Group), and is located approximately 10 kilometres north-east of the Frigg field in the North Sea.
The purpose of the well was to delineate the discovery. The well encountered a 177-metre gas column in the Brent Group with a substantial element of condensate in the gas. The appraisal well shows that the size of the discovery probably lies within the uncertainty range of 10 – 17 million Sm3 of recoverable oil equivalents.
The well was not formation-tested, but comprehensive data collection and sampling have been carried out. The discovery is probably commercial, and a tie-in to one of the permanent facilities in the area is being evaluated.
This is the second exploration well in production licence 035 B. The area in this licence was carved out of production licence 035 on 26 November 2008. The appraisal well was drilled to a vertical depth of 4118 metres below sea level, and was concluded in the Etive Formation in Middle Jurassic rocks. The sea depth is 111 metres. The well will be plugged and abandoned.
The well was drilled with the semi-submersible drilling facility Transocean Leader based on cost-sharing between production licences 035 B and 362. The drilling facility will now be transferred to the Åsgard field in the Norwegian Sea for drilling of production wells for the operator StatoilHydro Petroleum AS.
