"We need a number of such discoveries in future to keep our processing facilities fully occupied and to continue developing the area," says Mr. Grindstad. Tyrihans is regarded as a satellite to Statoil's producing Asgard field.
A natural development approach would accordingly be a direct subsea tie-in with the existing infrastructure on Asgard, once the basis for possible production has been clarified. Mr. Grindstad is very satisfied with the new Stena Don rig, which includes dynamic positioning among its capabilities.
The other discovery was made with exploration well 34/10-47S in the Dolly prospect, which lies north of Gullfaks satellites Rimfaks and Gullveig. Deepsea Trym recently completed the first section of the well, five kilometers from Gullveig. The results of an extensive logging and coring program are now being evaluated.
Hydrocarbons were also proven earlier this year in two structures – 33/9-8A Ole and 33/9-8S Dole – west of Rimfaks. "These are positive results," says Reidar Helland, manager of the Gullfaks resource development department. "Possible solutions for development as supplementary resources to the major Tampen area fields will be evaluated during the winter."
