StatoilHydro Proves Gas at Idun North Find in Norwegian Sea
Gas has been proven by StatoilHydro in exploration well 6507/3-7 Idun North in the Norwegian Sea. Currently being completed, the well is located two kilometers northwest of the Idun find and 12 kilometers north of the Skarv find.
The objective of the well was to prove petroleum in the Fangst and Bat group in Middle and Lower Jurassic reservoir rocks. The well proved gas in the Fangst group. The underlying Bat group was water-filled.The size of the discovery is estimated at between 0.6 and 3 billion standard cubic meters (Sm3) of recoverable gas. There is a potential for additional volumes beyond the proven gas volumes and further delineation of the discovery will be considered. The well was not formation-tested, but extensive data acquisition and sampling were conducted.
"Based on preliminary calculations, the size of the find is estimated at between 0.6 and 3 billion standard cubic meters (Sm3) of recoverable gas," said Knut Harald Nygard, who is heading StatoilHydro's exploration activities near existing fields in shallow waters in the northern part of the Norwegian Sea.
"There is also a potential of additional volumes, and further appraisal of the find will be considered."
The well was not formation tested, but extensive data gathering has been carried out.
"StatoilHydro and its partners in the production license will consider tying the gas find back to the production vessel for Skarv and Idun when it is in place," said Nygard.
This is the first exploration well in the carved out production license 159D. The licensees are the operator StatoilHydro with a 60% interest and E.ON Ruhrgas with 40%. In the original production license 159 six exploration wells have already been drilled.
Well 6507/3-7 was drilled at a water depth of 377 meters by the Ocean Vanguard semisub. Drilled to a vertical depth of 3,833 meters below sea level, the well was concluded in the Are formation of the lower Jurassic age. The well is being permanently plugged and abandoned.
