Italy’s oil and gas giant Eni has drilled an appraisal well for a depleted field in the UK sector of the North Sea to assess its potential for carbon capture and storage (CCS).

As disclosed in a social media post by Petrofac , 56 years after production from the Hewett field began, the company’s last operational team left the platform on their final flight. This marked the start of what is known as ‘lighthouse mode’ phase for the Hewett complex, denoting an asset that is no longer crewed or operational but not yet removed.
