Then a tube is inserted and cemented in place near the top. The relief well is angled into the primary well below the tube, forming a Y junction. In all other respects it is a clone of the primary well.

Tunnel boring from both ends, meeting in the middle, has been around since the early days of railways and was used on the Channel Tunnel. The drillers know exactly where the cutting head is.
