"I've condemned MANY Republicans for their actions before they were convicted" Like? You usually don't even condemn a Republican after they are convicted, you usually claim you know nothing about the conviction. Like, for example, Bruce Cunningham. Or all of those who got caught up in the Abramoff scandal. "but only when the guilt was self-evident -- which isn't the case with BP. " Uh, actually it is pretty clear that BP is guilty. They violated many safety protocols, that is pretty clear. Conclusions Well Planning * The hanger was run without a lock ring. Pressures from gas leaking up from the producing formation could have provided sufficient pressure to move the hanger and affect seal integrity. There was no lock ring or secondary seal (pack off) to prevent this. * Hanger was only a single barrier—the cement was and could not be tested. * Gas from the annulus getting past the hanger seal was the most likely source of the kick and subsequent blowout. Policy & Procedure * The method of conducting the inflow or draw-down test in conjunction with displacement of the well from weighted mud to seawater is suspect at best, and possibly fundamentally flawed. Basic Rig Practices * The inflow/draw down test did not appear to offer satisfactory results, and also took place over a relatively short period of time. * During the displacement of the well to seawater, volume, flow show and pressure anomalies were evident but did not result in the well being shut in in a timely manner. * Even after there were some indications that all was not well, pumping operations continued. Returns were dumped and the return flow meter was bypassed,so the rig was effectively blind until things started to get quite serious. * When the well was shut in, the drill pipe safety valve or IBOP was not closed in time to stop rapid rise in pressure getting back to the pumps and probably blowing the pressure relief valves. theoildrum.com
