Could you.................

Low tech solution:

Clear and level the area around the well as much as possible. I realize this is asking a lot being that it is one mile below SL.

Cast a LARGE slab of reinforced concrete on a barge. I thinking on the order of 20' x 20' x 8'. Lower it using a barge mounted super crane onto the well head.

Well stops flowing or will it just find the path of least resistance and flow out from under the slab?
