Equinor Energy AS will extend operations at the Heimdal gas center in production license 036 in the northeastern North Sea to 2023 (OGJ Online, Apr. 13, 2021).
Production from Valemon gas and condensate field, which is processed by Heimdal, is expected to increase as 3-4 new gas wells are to be drilled in 2021 and 2022. Thus, Heimdal will maintain profitable operations longer than 2021 or 2022 as originally planned.
When Heimdal operations end in 2023, remaining gas reserves at Valemon will be transferred to Kvitebjørn and Kollsnes for processing. Gassled, a joint venture operated by national company Gassco, will reconnect the dry gas pipelines currently passing over Heimdal to a subsea bypass.
After shut-down, Heimdal platforms are scheduled to be removed from 2025-2027 and brought ashore at Eldøyane, Stord, for scrapping, reuse, and recirculation.
Since start-up in 1985, Heimdal has produced 46 billion std cu m of gas and 7 million cu m of liquid (oil-condensate), corresponding to 332 MMboe. Additionally, Heimdal has processed similar volume from satellite fields Huldra, Skirne, Atla, Vale, and Valemon.
Equinor is operator at Hemdal with 29.4% interest. Partners are Petoro AS (20.0%), TotalEnergies SE (16.7%), Spirit Energy AS (28.8%), and LOTOS Exploration and Production Norge AS (5.0%).
