Statoil Digs Deep, Discovers Gas in Norwegian Sea
Statoil has discovered gas two kilometers southwest of the Norne field in the Norwegian Sea during the drilling of exploration well 6507/3-8.
A gas column 143 meters high was identified in the Fangst and Båt group of the Middle and Lower Jurassic, with good reservoir properties.
The find is estimated to contain 1.3-1.5 billion standard cubic meters (scm) of recoverable gas.
"This discovery lies in an area where we've made a number of earlier finds," explained Geir Richardsen, head of infrastructure-led exploration in the Norwegian Sea.
"With detailed surveying and evaluation enhancing our knowledge, this area is still considered prospective."
No formation test was carried out in the well, which lies in 378 meters of water, but extensive data was gathered and cores were taken.
The well was drilled to a total measured depth of 2,968 meters below sea level and terminated in the Lower Jurassic Tilje formation. It will now be permanently plugged and abandoned.
Producing the discovery through a tie-in to Norne will be considered by the licensees in production licence 159 B.
This is the second well in the license, which was awarded in 1989 as part of the 12B licensing round and carved out from PL 159 in 2004.
Well 6507/3-8 was drilled by Diamond Offshore's Ocean Vanguard semisub, which will now move to PL 057 in the North Sea to drill exploration well 34/4-12S for Statoil as operator.
The group has an 85% interest in PL 159 B, with Dong E&P Norge AS holding the remaining 15%.
