Equinor and partners Shell and Total have completed the drilling of confirmation well 31/5-7 Eos south of the Troll field in the North Sea. The purpose was to determine the suitability of the reservoir in the Johansen formation for carbon dioxide (CO2)storage.

“This is an important milestone in realizing the possibility of a CO2 storage on the Norwegian continental shelf,” said Geir Tungesvik, Equinor’s senior vice president for project development. “The preliminary results from the well so far have been positive. The drilling results will now be further analyzed before concluding.”

Extensive amounts of data have been acquired through coring, logging, sampling, and a production test. So far, a sealing shale layer and the presence of good quality sandstone in the reservoir have been identified.

The partners in Northern Lights are analyzing these results as part of their final project’s decision process.

In line with a shared vision to stimulate necessary development of future carbon capture and storage (CCS) projects through sharing, the partnership has decided that well data can be shared freely with external parties. The information, therefore, will be available for download. The solution is not yet decided.

Located some 2500 m below the seabed, this is the first well drilled in Exploitation License 001. If the Northern Lights project is sanctioned, the well will be used for injection and storage of CO2.
