BP: LMRP cap collected 11,100 barrels in 24 hours; remaining oil is still spilled into the Gulf. BP will provide rate of collection every 12 hours starting June 7.
Currently preparing two backup setups, to be introduced in mid June (choke and kill lines suction) and end of June (submerged riser)

Bloomberg Video (via YouTube.Com): Chianelli Says Add Nutrients to Help Microorganisms to Digest Spilled Oil
WSJ.com: BP Cap Collects 10,500 Barrels a Day, but a lot of oil is still spilling into the Gulf of Mexico. The estimate of spilling 19,000 a day is very likely, based on the amount of oil still escaping. BP is attempting to determine how many out of 4 valves to close on top of the cap. Valves were set on top of the cap to minimize initial pressure. One valve is reported to be closed already. BP is adjusting remaining three valves to maximize amount of oil collected. BP says closing all valves will render system “unstable”.
See attached video snap shots of escaping oil.

A cap placed on top of BOP above the leaking well was funneling some oil and gas to a surface ship, though oil continued to escape from under the bottom of cap and through four open vents on top of the device. Methanol is being pumped into the cap to prevent the formation of icy hydrates that could plug the mile-long pipe rising from the cap. Engineers hope to capture more oil by progressively closing the cap vents in coming days.

Summary: LMRP cap collected 6,077 barrels of oil during Friday, June 4, 2010, but a large amount of oil is still escaping. Enterprise Drillship has the procedure in place to “flare out” all natural gas coming up the pipe.
BP’s update as of June 5, 2010 9:00am CDT
• The LMRP cap was placed on top of failed BOP at MC252 well at approximately 8:35 pm CDT on June 3.
• Gas first reached the Discoverer Enterprise at approximately 11:00 pm CDT on June 3; oil followed at approximately 11:10 pm CDT.
• On June 4, a total of 6,077 barrels of oil was collected and 15.7 million standard cubic feet of natural gas was flared.
• Optimization continues and improvement in oil collection is expected over the next several days.
The live shots of video feeds (below) indicate that a large quantity of oil is still leaking into the Gulf. It also indicates a lot more than BP’s estimate of 5,000 barrel a day were leaking into the Gulf of Mexico.

Art Berman’s insight into causes of Deepwater Horizon Blowout
Source: http://www.theoildrum.com/node/6493
Exerpt from the article:
The blowout and oil spill on the Deepwater Horizon in the Gulf of Mexico was caused by a flawed well plan that did not include enough cement between the 7-inch production casing and the 9 7/8-inch protection casing. The presumed blowout preventer (BOP) failure is an important but secondary issue. Although the resulting oil spill has potentially grave environmental implications, recent efforts to limit the flow with an insertion tube have apparently been effective. Continuous efforts to slow or stop the flow include drilling two nearby relief wells that may intersect the MC 252 wellbore within 60-90 days.
