BP's estimate of the Macondo Blowout

What Did BP think the flowrate of Macondo was while it was still flowing into the Gulf?

Well, there’s now an answer to that question.  This document is related to the Riser Insertion tool where dispersant would be injected into the wellhead.  You want to inject dispersant at an optimum ratio to the oil flowing.  For example, let’s say for every 10 barrels per day flowing, you want to inject 1 gallon of Corexit.  If you’re planning on injecting 10 gallons of Corexit, you then probably think there’s 100 barrels per day flowing. 

Take a look at Page 4 (and also note the document is dated July 6th, while the well was still flowing):


Bingo.  BP’s working assumption on the flowrate of the Macondo blowout DURING THE BLOWOUT was 53,000 Barrels per Day, which, by the way, also happens to be nearly spot on to the government’s spillrate calculation during the trial.  

UPDATE: I've had this conversation a few times with people.  Most everyone assumed BP lied about the flowrate during the blowout.  I paid very close attention and, if you watched closely, it usually wasn't BP making the "5,000 Barrels per day" estimate of the flowrate. It was usually a USCG officer saying, but they were always standing right next to BP, especially Doug Suttles:


I've repeatedly told folks that, if you paid very close attention, BP didn't actually lie about the flowrate. They used a USCG officer as a shield to save themselves a few nickels.  That's not lying; that's far worse.  It's cowardice.
