Shell completes restart of operations at the Pierce Field in the UK North Sea after major redevelopment to enable gas production
Shell U.K. Ltd, a subsidiary of Shell plc, has completed the restart of operations at the Pierce field in the UK Central North Sea, following a significant upgrade to allow gas to be produced after years of the field producing only oil. Pierce is a joint venture between Shell companies (operator, 92.52%) and Ithaca Energy (UK) Limited (7.48%.), according to the company's release.
Substantial modifications were made to the Haewene Brim floating production, storage and offloading vessel (FPSO), which is used to produce hydrocarbons at the Pierce field. A new subsea gas export line was also installed, connecting to the SEGAL pipeline system, which brings gas ashore at St Fergus, north of Aberdeen.
To enable the upgrade, the FPSO, which is owned and operated by Bluewater, stopped producing in October 2021. It then spent six months in dry dock where it was transformed into a vessel that could also produce gas, which had previously been re-injected into the reservoir.
Peak production is expected to reach 30,000 barrels of oil equivalent per day, which is more than twice the production prior to the redevelopment, with more gas being produced than oil. The gas will be sent through newly installed subsea pipelines and the oil will be transported by tanker, as before.
