why can't we do our own "Expert" Analysis?
the only difference is we won't be on anybody's payroll,
ok, we start here>
"he Gulf of Mexico basin resembles a large pit with a broad shallow rim. Approximately 38% of Gulf waters are shallow intertidal areas. The waters of the continental shelf (<200 m) and continental slope (200-3000 m) represent 22% and 20% respectively, and abyssal areas deeper than 3,000 m comprise the final 20%. Located in the southwestern quadrant, the Sigsbee Deep is the deepest region of the Gulf of Mexico and contains depths of up to 4,384 m. The mean (average) water depth of the Gulf is ~1,615 m and the basin contains a volume of 2,434,000 cubic kilometers of water (6.43 * 1017 or 643 quadrillion gallons).

ok, we have 643 quadrillion gallons of salt water.
somebody help and convert the estimated max oil spillage in gallons,

here is where things started to go real bad>
" * April 15 - Morel informs Halliburton executive Jesse Gagliano that they plan to use 6 centralizers. Gagliano says they should use 21. Morel replies in an email, "it's too late to get any more product on the rig, our only option[] is to rearrange placement of these centralizers." Gagliano also recommends to circulate the drilling mud from the bottom of the well all the way up to the surface to remove air pockets and debris which can contaminate the cement, saying in an email, at "least circulate one bottoms up on the well before doing a cement job." Despite this recommendation, BP cycles only 261 barrels (41.5 m3) of mud, a fraction of the total mud used in the well.[11]
* April 15 - MMS approves amended permit for BP to use a single liner with fewer barriers.[11]
* April 16 - Brett Cocales, BP's Operations Drilling Engineer, emails Morel confirming the 6 centralizer approach.
* April 17 - Deepwater Horizon completes its drilling and the well is being prepared to be cemented so that another rig will retrieve the oil. The blowout preventer is tested and found to be "functional."[18] Gagliano now reports that using only 6 centralizers "would likely produce channeling and a failure of the cement job."[11]
* April 18 - Gagliano's report says "well is considered to have a severe gas flow problem." Schlumberger flies a crew to conduct a cement bond log to determine whether the cement has bonded to the casing and surrounding formations. It is required in rules.[11][10]
* April 19 - Halliburton completes cementing of the final production casing string.[19]
* April 20 -
* 7 am - BP cancels a recommended cement bond log test. Conducting the test would have taken 9–12 hours and $128,000. By canceling the cement test BP paid only $10,000. Crew leaves on 11:15 am flight.[11] BP officials gather on the platform to celebrate seven years without an injury on the rig.[20] The planned moving of the Deepwater Horizon to another location was 43 days past due and the delay had cost BP $21 million.[21]
* 9:45 p.m. CDT - Gas, oil and concrete from the Deepwater Horizon explode up the wellbore onto the deck and then catches fire. The explosion kills 11 platform workers and injures 17 others; another 98 people survive without serious physical injury.[22]
so three things did em in,
1)they did not use the right forms for the cement job,
2)they did not clean the bore before the cement job,
3) they did not test the cement job
three strikes and ka Blam!
your down and out.

there were many more than 3 bad decisions that lead to this disaster...
ignoring the presence of rubber chunks in the mud
ignoring failed BOP tests
prematurely replacing the heavy drilling mud with sea water after the cement job
to name a few more

and the moral of the story is to not hire Morel as your engineer.
weird how one guy can drain 50 billion out of a company/

For those of you who are so quick to point fingers, Obama was not in the gulf today, so save your breath. He did not cause this.
