16/11/2009 Statoil Petroleum AS, operator of the Sleipner Vest field in production licences 029 and 046, has concluded the drilling of a development well with an exploration target.
Well 15/9-B-1 was drilled about 1.5 km west of the Sleipner Vest field and 4 km from the Sleipner B platform in the central part of the North Sea.
The objective of the well was to prove petroleum in Middle Jurassic reservoir rocks (the Hugin formation), as well as to place relevant volumes in production via the production facility on the Sleipner B platform. The well encountered gas-condensate in the Hugin formation. Preliminary estimates indicate the size of the discovery at between six and ten million standard cubic metres (Sm3) of recoverable oil equivalents. The well was not formation-tested, but data acquisition and sampling have been carried out. The licensees will produce the discovery via the Sleipner Vest field.
Production licence 029 was awarded in the 2nd licensing round in 1969, and production licence 046 was awarded in the 3rd licensing round in 1976. The well was drilled to a vertical depth of 3760 metres below the sea surface, and was terminated in the Hugin formation in the Middle Jurassic. The water depth is 108 metres. The well will now be readied for production.
Well 15/9-B-1 was drilled by the West Epsilon drilling facility, which is connected to the Sleipner B platform. West Epsilon will now drill a new development well, 15/9-B-2, on the field.
