Deepwater Horizon - Transocean Oil Rig Fire

[QUOTE=charles_oil;40097]In the plan for the casing and cementing , the negative test was to be done with base oil = this would have been a better test (greter differential on seal assembly) than just using seawater

Anyone know why it was changed?? I have not heard any mention of this in any dicoument (including the lastest “anomolies” one)

The document looks like the program as issued from the beach. These are then often changed by the rig staff into something like ‘daily instructions’. Would like to see a copy of those, if they are available. If something crittical is changed (like inflow testing with seawater instead of base oil) then an amendment to the program should also have been issued from the beach.
