Wildcat well 6507/2-2 made a discovery in 1992 with a volume of approximately 6.7 billion Sm3 of recoverable gas and 0.4 million Sm3 recoverable condensate in upper and lower Cretaceous reservoirs. The discovery is located approximately 21 km southwest of the Norne field.
The objective of well 6507/2-4 was to appraise the discovery and prove additional economical reserves. The well proved gas and condensate in a position 4.5 km from the discovery well. The appraisal well indicates that the total size of the discovery is within the range of 12 – 19 billion Sm3 of recoverable gas and 0.8 – 1.1 million Sm3 of recoverable condensate. The well was not tested, but extensive data collection and sampling were carried out. The results from the well are encouraging with respect to future development of the discovery.
This is the fourth exploration well in production licence 122. Production licence 122 was awarded in licensing round 10B in 1986.
The appraisal well 6507/2-4 was drilled to a vertical depth of 3584 m below the sea surface and was completed in rocks of lower Cretaceous age. The water depth is 365 m, and the well will be permanently plugged and abandoned. Well 6507/2-4 was drilled with the semisub West Alpha, which will go to the Norwegian Sea to drill exploration well 6507/11-9 in production licence 263 with StatoilHydro as operator.
