OK, I read back and if you're talking about drilling the cement plugs and why set so much casing, here goes.
The cement is real easy to drill in a cased hole and it can be drilled back to TD fairly easy. But, as I recall Pup said something had to be set on the gulf floor and drilled through on a production well. I think he called it a spider. I don't know about that, but, in the patch, where there is a will there is a way.

Most deeper wells drilled have casing cemented just above the pay zones, for several reasons. It holds the BOP better than surface pipe would in case high pressure is hit. It lets you run high wt. mud to hold pressure that would break down the weaker zones above and in turn keeps the pressure from charging the weeker zones, with no cap rock, and comming to the surface a mile or two away.
Anyone remember the oil comming up 2 miles away from the BP blowout and they said it wasn't from that well? lol.
