In Norway, oil and gas majors 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 realising the possibility of CO2 storage on the Norwegian continental shelf,” says Geir Tungesvik, Equinor’s Senior Vice President for Project Development.

According to a statement, extensive amounts of data have been acquired through coring, logging, sampling, and a production test.
The preliminary results from the well so far have been positive. So far, we have proven a sealing shale layer and the presence of good quality sandstone in the reservoir. The drilling results will now be further analysed before concluding, said Geir Tungesvik.
In line with a shared vision to stimulate the necessary development of future carbon, capture, and storage (CCS) projects through sharing, the partnership has decided that well data can be freely shared with external parties and the information will, therefore, be available for download. The solution is not yet decided.
Located some 2 500 metres 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 carbon dioxide (CO2).
The Northern Lights partners plan for a potential investment decision in the spring of 2020. Such an investment decision is subject to agreement between the partners and government authorities on an implementation agreement, as well as ESA approval of the project.
The project is subject to final approval by Norwegian authorities.
