Perenco is celebrating the successful conclusion of the UK’s first carbon dioxide injection test for carbon capture and storage (CCS).
This test saw the injection of CO2 into a depleted natural gas reservoir in the Uk’s Southern North Sea. This marked a “major milestone” for Project Poseidon, with the injection test delivered to plan. A total of 15 injection cycles were performed in the Leman gas field, mobilising 11 CO2 offshore batch refills. According to Perenco, there were no injection issues and an “exceptional” dataset was amassed in the process.
Petrodec’s ERDA rig – the first to have achieved an approved safety case for CO2 injection support – has now sailed away from the Leman 27H platform, with attentions now turning to interpreting the results and converting new insights into an evidence-based development plan for Project Poseidon for the Perenco CCS team and its joint venture partners, Carbon Catalyst and Harbour Energy.
As well as showing that carbon storage can be a reality for depleted fields of the Southern North Sea, the partners noted the project thus far has also shown how it is possible to widely reuse petroleum production infrastructure to unlock cost effective projects.
