StatoilHydro's Smorbukk Appraisal Hits Hydrocarbons

StatoilHydro has confirmed the existence of oil, gas and condensate in the northeastern part of the Smorbukk deposit, which is part of the Asgard field in the Norwegian Sea.

The result is encouraging and development in association with the Asgard B platform will be considered.

StatoilHydro has completed the drilling of an appraisal well in the northeastern segment of the Smorbukk deposit. The proven resources are so far estimated at between 15 and 25 million barrels of recoverable oil equivalent.

"The team has done a great job identifying the area and drilling the appraisal well, and we are very pleased with the result," said Svein Hatlem, vice president for Asgard production.

Being part of the Asgard field the segment is included in the plan for development and operation (PUD) of the area.

The Asgard 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 Smorbukk field has been on stream since 1999.

"The proven resources may allow a new subsea template to be tied in to the existing infrastructure on the Asgard field," said Tore Kulset, asset owner representative for the Smorbukk Northeast project.

"Development would be positive with regard to further activity in the area," Kulset added. Production from the segment may be possible in three to four years, he suggested.

The main purpose of the well was to confirm the existence of hydrocarbons in Mid/Lower Jurassic reservoir rocks in the northeastern segment of Smorbukk, 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 semisubmersible Transocean Leader drilling unit.
