UK’s first CO2 injection test for the Poseidon carbon capture and storage (CCS) project, which will store CO2 at Perenco-operated Leman gas field in Southern North Sea, has been completed.
The test involved the injection of CO2 into a depleted natural gas reservoir in the UK’s Southern North Sea, marking a major milestone for Project Poseidon and the UK’s broader decarbonization strategy.
Petrodec’s ERDA, the first rig in the UK to have achieved an approved safety case for CO2 injection support, has now sailed away from the Leman 27H platform.
This marks the end of the test which was carried out by the Project Poseidon joint venture, comprising Perenco UK, Carbon Catalyst, and Harbour Energy.
The Poseidon injection test delivered to plan with a total of 15 injection cycles performed into the Leman gas field, mobilizing 11 CO2 offshore batch refills.
The operational program was performed in a timely and safe manner, without injection issues and, importantly, with the acquisition of an exceptional dataset, Perenco said.
The operation proves not only that CCS can be a reality for depleted fields of the Southern North Sea, but also that it is possible to widely reuse petroleum production infrastructure to unlock cost effective projects, the company noted.
“This test has met our expectations, both in terms of technical execution and the quality of data gathered. These insights are instrumental as we move to the next phase of developing the Poseidon Project.
“The successful test highlights the role our industry can play in the UK’s decarbonization efforts. The Perenco CCS team and our joint venture partners are now fully focused on interpreting the results and converting new insights into an evidence-based development plan for Project Poseidon,” said Armel Simondin, CEO, Perenco.
