BP induced problems??

1) Your first regarding the pipe used for the casing is irrelevant, the casing still holds good to this day.

2) The second relating to the cement job. What cement job were they talking about? the one to initially set the casing? Or the one to temporarily cap the well? The first calls for the outer casing sections to be perforated, the last does not as the cement is used to form a plug. Again the blow-out has got nothing whatsoever to do with the cement

3) Gas "kicks" and gas build up in the reservoir are exactly what the BOP is intended to cope with. The BOP failed, the BOP is designed and fitted out with 100% redundancy as far as operating systems go. One pod was leaking and no information as yet has been given as to exactly what the source of that leak was and how that leak would affect the operating capability of that pod. The other pod was functioning normally and was not subject to any leakage. Had either Government Agency or BP personnel ordered a shut down then exactly the same operations would have been undertaken to enable recovery of the leaking pod or BOP to surface.

4) "Pipe falling into the well" Q? All that does is that it indicates carelessness on the drill floor by Transocean personnel, nothing to do with BP at all.
