Gas Storage Denmark A/S, a part of Energinet, has the intention to perform final plug and abandonment operations on their wells near to the town of Tønder planned for execution from Q3 2023.

The three wells were drilled and tested in the early eighties (1983/1984). The wells were drilled to evaluate the possibility to establish natural gas storage facility, however, the gas storage facility was never established and it has been decided to plug and abandon the well permanently.

The wells were drilled to a depth of 1636 to 1847 meter. The three wells have never been used for production or gas storage.

Appendix-2A SOW, outlines the specifications of the tender to perform a safe and efficient execution of the P&A operations of the wells Tønder‐3, Tønder‐4, and Tønder‐5 and has to be read together with the related appendices hereunder Appendix 2B, the Plug and Abandonment draft working programs for the three wells.
