LONDON, May 20 -- Norway's StatoilHydro has discovered 63-107 million boe from two wells on the Fulla prospect in the North Sea, which could be tied into the installations near Lille Frigg field.

"The discovery has not been tested, but extensive data collection and sampling have taken place," said StatoilHydro.

The company will permanently plug and abandon well 30/11-7A, which reached a TVD of 4,118 m below sea level in 111 m of water. The well struck gas and condensate in Mid-Jurassic reservoir rocks during the drilling of a sidetrack on Fulla, 10 km northeast of Frigg field.

StatoilHydro struck small volumes of gas in the exploration well in February (OGJ Online, Feb. 2, 2009). Total SA's Frigg gas field is being decommissioned and is expected to be finished next summer.

"Gas reserves of this size within infrastructure-led exploration provinces are of commercial interest and the discovery may help maintain the operation of installations in the Frigg and Heimdal areas," said Tom Dreyer, StatoilHydro's vice-president for infrastructure-led exploration in the North Sea.

"The discovery is a result of thorough interdisciplinary work over several years. We saw the potentials for good reservoir properties in this area at an early stage, and our interpretation of the subsurface was sustained by the discovery of this gas column," Dreyer added.

The Fulla prospect is on production licenses PL362 and PL035B. The Fulla licensees are: Dana Petroleum Norway with 10%, DNO AS with 15%, Svenska Petroleum Exploration with 25%, and StatoilHydro with 50%.

The partners used the Transocean Leader drilling unit on Fulla, which will now move to Asgard field on the mid-Norwegian continental shelf to drill other StatoilHydro-operated wells.
