[QUOTE=ExCompanyMan;40462]Tend to agree but still would like to get it confirmed with a simulation. Look, the BOP did not close in the well, and failed it main purpose, either because there was a leak and it did not receive the signal (unlikely) or because the casing moved up and prevented the rams from closing around the DP. Also remember that if there was a leak going up the annulus then hot reservoir fluids would be traveling up; so you would have cold sea fluid in the casing and hot reservoir fluid behind it; god knows the effect on the steel with that.
Just brain storming…[/QUOTE]
Remember also that at one point they dropped the drillpipe pressure to zero (not easy to interpret from the chart data we have. They could have also isolated the DP string readings!).
That would drop the hydrostatic below that DP by approx 2350psi ie +/-950psi more than they had “planned” for.
