Mark Hafle, the BP drilling engineer who wrote plans for well casings and cement seals on the Deepwater Horizon's well, testified that the well had lost thousands of barrels of mud at the bottom. But he said models run onshore showed alterations to the cement program would resolve the issues, and when asked if a cement failure allowed the well to "flow" gas and oil, he wouldn't capitulate.
Hafle said he made several changes to casing designs in the last few days before the well blew, including the addition of the two casing liners that weren't part of the original well design because of problems where the earthen sides of the well were "ballooning." He also worked with Halliburton engineers to design a plan for sealing the well casings with cement.

"Don't you think for that size casing, you set up your Halliburton cementer for failure, especially when you had a loss return zone (where drilling mud was seeping into the earth) below the hole?" McCarroll pointedly asked.

#1 - Mon Jan 30, 2012 4:24 PM ESTHafle gave what appeared to be conflicting testimony about the cement bond log, considered by engineers to be the "gold standard" of testing cement jobs. Initially, when asked why no cement bond log was conducted, Hafle said it was because "we had not gotten that far in the well plan when the incident (blowout) occurred." But later on, he said there was no plan to conduct the test and the crew was about to close off the well with a final plug, which would close of the well to cement bond log tests.

Great find! & Hafle said it was because "we had not gotten that far in the well plan when the incident (blowout) occurred."
Bloody Hell how can you do any kind of construction or anything else WITHOUT a plan? A plan that has been drawn up by engineers, pre-approved, & having a safety back up plan as well? I have never heard of such a thing.
Damn it's like going into exploratory surgery, no we're not always sure what we may find but we Bloody Hell know what to do once we're in there, whether it's a foreign body, an intussusseption, or even if the patient starts crashing on the table, we are prepared & know what to do & have emergency drugs on hand, blood transfusion, whatever it takes. And no we can't save them all but at least we are prepared to handle the situation.
What a bunch of Flaming Idiots ALL of those who let each phase from getting the permits to drill in the 1st place & to the ones that didn't do their jobs & properly check each phase of the project before it even began. Sorry this really angers me because there is NO EXCUSE PERIOD!
Cheers
