Equinor and its partners have decided to extend operations at the Heimdal gas centre in the Norwegian North Sea until 2023.
The decision comes as the partners plan to drill new wells at the Valemon field, which is located between production licences 050 and 193.
The subsequent production is transported to Heimdal gas processing and distribution hub, which comprises an integrated steel platform and a new riser platform.
During 2021-2022, the partners are planning to drill three to four new gas wells at the Valemon field to boost its production.
This is expected to help the Heimdal Gas Centre to sustain profitable operations slightly longer than its original closure date in 2021 or 2022, Equinor said.
The gas centre mainly processes gas produced from the satellite fields Huldra, Skirne, Atla, and Vale, as well as minor gas volumes from the Heimdal reservoir itself.
The company anticipates the extension of operations of the Heimdal gas centre to be useful from a socioeconomic perspective.
It would also enable the production of the remaining reserves in Skirne and Vale while boosting production from the Valemon field.
Equinor exploration and production west senior vice-president Geir Sørtveit said: “Heimdal is an important field that has repeatedly led the way for the Norwegian petroleum industry. First by contributing to the construction of Statpipe, which is a cornerstone for Norwegian gas export to Europe.
“Then by capturing value also after its own resources were produced. Heimdal illustrates how investments in infrastructure offshore drive future value creation opportunities.”
Once the Heimdal gas centre is retired in 2023, production from the remaining reserves at the Valemon field will be transferred to Kvitebjørn platform and Kollsnes facility for processing.
Equinor operates the Heimdal field with a 29.4% stake, partnered with Petoro (20%), TotalEnergies (16.7%), Spirit Energy (28.8%), and LOTOS Exploration and Production (5%).
