They knew that well-casing was there - although they may not have had the proper cutting heads installed at the time. But I guess that is pretty common do just drill through them. Some towns are filled with old oil and gas wells. (This one was a relatively small water well done to test the geology for the tunnel).
They had the over heating problem from very early on (before they hit the casing) - so I think there might be a bigger problem. This is the largest tunnel machine ever built. Although one would hope they did some test tunnels before they shipped it - but I doubt it.
5 years from now there will be a rusting hulk in a pit.
