Seek, there are many different ways of doing things when drilling a hole of this size.
After rigging up we always nippled up on the 30" conductor with a riser pipe, annular BOP like is on top of that stack and flow pipe, all to get the cuttings & mud high enough to go into the shale shaker and pits. Run in a 26 1/2" bit and drill surface. Take all that off and run 20" surface pipe. Cement it from bottom to top and set slips in surface head. Screw a flange on surface pipe and install all BOP's. Drill intermediate, do all this again and go in with slim hole collars and everything.
So if they nippled up on the intermediate to drill the pay zones and the stack is still there, I don't think the well is plugged. Why leave a million or so bucks worth of intermediate pipe when most can be pulled back out??

Like I say there are many ways of doing this and mine may be old school today. :)
