My rough calculations say that for a 4 inch id and 100,000 psi, the
wall thickness would have to be about 4 inches if you used HSLA
steel. And that is without any safety factor. Time for nanotubes.

The last casing set to complete the well was 7 inch. I think you can
assume a safety factor of at least 2 and probably more. From what I
read the 7 inch was hung off at the well head, so it extended the
entire depth of the well. Calculate what the weight of the entire
string of 7 inch was and how much the derrick had to support to handle
that string and I'll ask my drilling superintendent buddy that the
capacity of the BP rig was.
