StatoilHydro has struck gas during the drilling of a sidetrack on the Fulla prospect ten kilometers northeast of the Frigg field in the North Sea.
Earlier this year an exploration well on the same prospect encountered small volumes of gas.
The combined volumes proven through the two wells are estimated at between 63 and 107 million barrels of oil equivalent.
"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 located close to the abandoned Lille Frigg field, and tie-in to one of the fixed installations in the area will now be considered.
"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 sub-surface was sustained by the discovery of this gas column," Mr. Dreyer says.
Well 30/11-7A struck gas with a considerable content of condensate in Mid-Jurassic reservoir rocks.
The Fulla prospect belongs to production licenses PL362 and PL035B. The Fulla licensees are: Dana Petroleum Norway (10%), Det norske oljeselskap (15%), Svenska Petroleum Exploration (25%) and StatoilHydro (operator, 50%).
