Frigg gas field, one of Norway's oldest offshore producers, is the center of a new round of activity.
Norway's Den norkse stats oljeselskap AS has bought an added 15% interest in field facilities from operator Elf Aquitaine Norge AS, boosting its total holding to 20%.
The life of field facilities in Block 25/1 will be extended by Elf's decision to process oil from Froy oil and gas field on Frigg's TCP2 platform, 22 miles away.
Elf has submitted a development plan for Froy in Blocks 25/2 and 25/5 to Norway's Ministry of Petroleum and Energy. It centers on an unmanned minimum facilities platform for first stage separation from five production wells. There also will be four water injection wells.
If Norway's Storting (parliament) approves the 3.8 billion kroner ($638 million) plan before summer, Elf expects to have the field on stream by 1995. Froy's reserves are 94.5 million bbl of oil and 113 bcf of gas.
A new crude stabilization module will be required on TCP2. Oil will move from Frigg through a new 51 mile, 16 in. line named Frostpipe. It is to run to Norsk Hydro's Oseberg Platform A and into the crude oil pipeline to the Norwegian mainland. Oil production is to peak at 38,000 b/d.
About 44 MMcfd of gas will move through existing pipelines to the U.K. and could be used as part of the volumes for the proposed supply contract with British electricity generator National Power.
The main Frigg reservoir is in the final stages of depletion. Production from various satellites will keep processing units operating until the end of the century.
