Carbon Catalyst & Poseidon prepare for UK’s first CO2 well injection test

Carbon Catalyst Limited has announced the mobilization by the Poseidon partners of the Petrodec HAEVA offshore workover rig, now on location at the Leman Hotel wellhead platform in the UK Southern North Sea.

This marks the beginning of the company’s preparatory well operations, setting the stage for the commencement of the UK’s first CO2 well injection test later this year. This 30-day operation entails the workover of the Leman 27H gas production well and completion of the well into a CO2 injector.

Poseidon envisions the permanent geological storage of approximately one billion tons of CO2 into the UK’s largest depleted gas field, the PUK-operated Leman gas field, and other adjacent storage reservoirs within the carbon storage license.

The project is scheduled to be operational by 2029, with initial CO2 injection rates of 1.5 million tons per annum (Mtpa), increasing to 40 Mtpa over a 40-year period. Poseidon will connect a wide range of CO2 emitters across East Anglia, London, and the wider Southeast of the UK via the PUK-operated Bacton Gas Terminal to the offshore Poseidon geological storage sites.
