OSLO -- StatoilHydro has discovered hydrocarbons in two wells in the Oseberg area in the Norwegian sector of the North Sea. The first discovery was made in a long-reach exploration well from the Oseberg C platform, targeting the Cook Formation in the Theta structure.
"The well is designed to be converted to a producer within 45 days after the discovery, giving an extremely quick turnover from prospective resources to producible reserves," says Trond Eide, Oseberg Petech project leader.
"Work is currently underway to determine the optimal production solution," says Bjørn Inge Braathen, leader of the exploration team working in the Oseberg area. Depending on the development solution, preliminary expected volumes are around 5 MMbbl of oil.
Oil and gas was also found in the Delta S2 structure in the Oseberg South area. The Delta S2 discovery targeted the Brent Group, and is believed to contain about 16 MMbbl of recoverable oil equivalents. Well 30/9-21S was drilled byTransocean Winner, and the rig is now drilling a second branch to test the nearby Richards prospect.
"We have been excited about the prospectivity of the Oseberg area for a long time, and after a few years of limited exploration in the area it's good to see that the efforts are stepped up in a successful manner," says Tom Dreyer, VP for infrastructure-led exploration North Sea.
According to the company, the Delta S2 discovery may be tied to the nearby Delta template within a few years, and continued exploration success in the area may trigger new development solutions.
