[QUOTE=New Orleans Lady;39382]the “root cause analysis” is esp interesting…sounds like the author, was a frequent flyer here, hhhmmm anyone dare to guess who?[/QUOTE]
NO Lady, just to (kinda’) clear things up a bit.
Back around the time the Forum went South, I had asked the creator of the site, Michael Davis, via E-mail, a question that was posed by Alcor. Copy below:
"Hi Michael
If you have the time, could you please stop by:
‘alcor’ has asked:
“Do you have contact with the author? Where did he arrive at a figure of 4.1 Bbl Gain?
It relies heavily on mud being lost to the weak zone, allowing gas to expand. And conveniently, the figures result in gas
below the Seal Assy which will not eject the Hanger.
Has he arranged the ‘gain’ value to suit his own purposes?
Do you have any other interpretation?”
The spreadsheet is titled, “Force To Lift Macando Casing Hanger When Seated and Unseated.xlsx”, and I can’t see the
’seated vs. unseated’ parts. Locking ring?
Thank you in advance if you can make it by.

And I wrote back with:
"Thanks for the prompt reply, Michael
.
He asks again, "Where did he arrive at a figure of 4.1 Bbl Gain?
What he’s saying is, how did you come up with the 4.1 number?
Thanks again,
–Michael (tvhawaii)"
And he never replied. The document in question was hyperlinked within:Deepwater Horizon Blowout Root Cause Analysis.docx and the link was:
Force To Lift Macando Casing Hanger When Seated and Unseated.xlsx
At that time, the link opened a spreadsheet titled "Casing Pressures.xlsx, which I’m unable to attach because I get “Invalid File”. But -now- when you open that link, you get a totally different spreadsheet which doesn’t mention anything about the mysterious 4.1bbls.
I leave it as an exercise for the reader to figure out what happened and if anyone wants to see the original, PM me with your E-mail address and I’ll send it to you.
