StatoilHydro has confirmed the existence of oil, gas and condensate in the north-eastern part of the Smørbukk deposit, which is part of the Åsgard field in the Norwegian Sea.
StatoilHydro has completed drilling of appraisal wells 6506/12-12 S and 6506/12-12 A, in the north-eastern segment of the Smørbukk deposit.
The proven resources are so far estimated at between 15 and 25 million barrels of recoverable oil equivalent.
Being part of the Åsgard field the segment is included in the plan for development and operation (PUD) of the area.
The Åsgard field development includes 58 production and injection wells divided on 16 subsea templates.
Two vessels and one platform are located on the field.
Discovered in 1984, the Smørbukk field has been on stream since 1999.
The main purpose of the well was to confirm the existence of hydrocarbons in Mid/Lower Jurassic reservoir rocks in the north-eastern segment of Smørbukk and to delineate the discovery.
The well also penetrated the Grizzly prospect in Cretaceous strata. Small amounts of hydrocarbons were struck in sandstone in the Lange/Lysing formations. Extensive data acquisition was performed but these resources are not expected to be recoverable.
In addition, a sidetrack well was drilled for further data acquisition. The sidetrack is prepared for use as a future production well.
The wells were drilled by the semi-submersible Transocean Leader drilling unit.
