BP has now sent a reply to Admiral Watson in regard to the Coast Guard request that BP provide a “better” plan for dealing with the oil spill at the Deepwater Horizon site. In part, the response deals with increasing the capacity for the collection of oil through the provision of additional vessels; in part, by providing better for a Hurricane, and in part, by providing better back-up systems.
This post will go through and explain what the letter describes, and I intend, in a later post, to explain in more detail why BP should plan for a steadily increasing volume of oil. Simplistically, it is because the erosion from the sand in the oil continues to widen passages through the reservoir, the casing and lining of the well, and the blow out preventer (BOP). The latest "production" figures are
For the last 12 hours on June 14th (noon to midnight), approximately 7,800 barrels of oil were collected and 16.8 million cubic feet of natural gas were flared. On June 14th, a total of approximately 15,420 barrels of oil were collected and 33.2 million cubic feet of natural gas were flared.
The first step in the process begins almost immediately, and that is the redirection of oil, so that it flows up through the choke lines of the BOP to the Q4000. (corrected to remove the kill line, which is not being used - h/t rainyday)

The planned permanent solution for the BP Macondo spill in the Gulf of Mexico is the killing of the well by drilling a relief well to intersect the blowout wellbore, enabling the placement of high density mud and eventually cement. Currently, two relief wells are being drilled, one started on May 2 and the second on May 14 (although the latter was delayed a few days later on). On The Oil Drum and elsewhere, many have been questioning why only two relief wells have been sunk, given the risky and uncertain nature of the kill process and the long time lag in getting more wells drilled if the first two are unsuccessful. There are many technical, political, and economic arguments that can be used to justify the need for more wells. What I will do herein is develop a statistical model which can be used to weigh the potential benefits of additional wells added this late in the crisis. One of the more critical factors is time -- the time it takes before the blowout wells is killed. Does drilling more relief wells change the expected time before the kill?
"The true value of energy to society is the net energy, which is that after the energy costs of getting and concentrating that energy are subtracted.” - H.T. Odum (1973)
To reduce Odum’s assertion to a pithy phrase—it takes energy to get energy – and for the past 150 years society has accessed enormous quantities of energy in the form of fossil fuels at a very low cost. Early U.S. oil production provided 100 barrels of oil for every barrel spent in getting that oil (Cleveland 2005), while traditional fuel sources (e.g. biomass) returned much less. This huge increase in net energy enabled society to build cities, increase crop yields, build cars, etc…
Today, the circumstances are different, as nearly all of the easy-to-find and easy-to-produce oil wells have been found and produced. For example, Ghawar, the world’s biggest oil field, was discovered in 1948, and even with all of the advances in seismic technology over the past 60 years, nary an oil well of nearly the same magnitude has been found.

Senator Bill Nelson of Florida spoke on MSNBC on Monday, about the possibility of oil leaking up from the seabed in the vicinity of the Deepwater Horizon well that is currently spilling oil into the Gulf. (The implication being that the well casing had "sprung a leak.") The story will inevitably grow, but it may well be that he is confusing two quite separate events. You might remember that when tar balls first started appearing on the Florida beaches recently they were analyzed, and on May 19th the Coast Guard issued a statement that included the following:
A sampling of tar balls discovered on beaches at Fort Zachary Taylor State Park, Fla., Smathers Beach in Key West, Big Pine Key, Fla., and Loggerhead Key in the Dry Tortugas National Park, Fla. were flown by a Coast Guard HU-25 Falcon jet based in Miami, Fla., to New London, Conn. Tuesday for testing and analysis.
The results of those tests conclusively show that the tar balls collected from Florida Keys beaches do not match the type of oil from the Deepwater Horizon oil spill in the Gulf of Mexico. The source of the tar balls remains unknown at this time.
At that time it was conjectured that the tar balls had come from natural seeps under the Gulf. Cutler Cleveland recently wrote a guest post on the topic of these natural seeps, and their size, relative to the current spill, but because of the new furor I thought it worth expanding a little on what he wrote, relying on two of his sources – the National Research Council’s Oil in the Sea III Inputs, Fates and Effects (2003) ; and Dagmar Schmidt Etkin’s Report “Analysis of U.S. Oil Spillage,” which API issued last August.
Below the fold is rerun of an essay from Cutler Cleveland on energy transitions. The unfolding drama in the Gulf of Mexico serves as a reminder of how dependent our modern civilization has become on fossil fuels. Dr. Cleveland's essay provides an excellent big picture overview, especially for readers here new to the topic, of what supply side variables we need to consider as we transition away from our extreme fossil fuel subsidy. Replacing stock based (fossil) energy with flow based (renewable) is not as simple as one for one BTU substitution. Professor Cleveland previously wrote "Energy From Wind - A Discussion of the EROI Research", and "Ten Fundamental Principles of Net Energy" posted on theoildrum.com. Cutler Cleveland is a Professor at Boston University and has been researching and writing on energy issues for over 25 years.

BP's Deepwater Oil Spill - Matt Simmons on Dylan Ratigan Today, Closing the Relief Ports, and Open Thread 2
Matt Simmons has been making claims about other, perhaps larger, problem areas within the structure of the Macondo well--by which even more oil has been pouring into the Gulf of Mexico. We have not seen the evidence to support these claims, even though they have been mentioned in just about every thread we have put up.
Simmons was on with Dylan Ratigan today. That video is shown here in this evening's thread.
VIDEO BELOW FOLD
In May 2003, the Transocean drillship Discoverer Enterprise, under contract from BP, was getting ready to pull out of a nearly-completed development well for the Thunderhorse project in the Gulf of Mexico, about 40 miles south of the current (2010) spill at the Macondo prospect. For some reason, the ship was dragged off its position such that the riser reaching down 6000 feet to the well at the seafloor was snapped off in two places. In this case, a blind-shear ram blow out preventer (BOP) did its job, sealing off the well below and preventing what could have been the largest U.S. oil spill. As it was, the only thing spilled was the drilling mud remaining in the various riser pieces dangling from the ship, buried in mud, or stuck vertically into the seafloor. After rehabilitating the well and then taking stock of the fact that the unthinkable could have happened, BP and Transocean apparently decided not to think about it too much more.
But after reading through some MMS reports, it seems that near-misses happen a lot. Oops.

The decision to cut the riser and drill pipe (DP) from the top of the Blow-Out Preventer (BOP) as a first step in putting the Lower Marine Riser Package (LMRP) over the leaking oil well in the Gulf of Mexico is not quite as easy as it might sound to a layman. This post is going to talk a little about a couple of the problems, as well as an alternate way of doing it, and should end with a possibly slightly amusing anecdote.
The current plan is to carry out the operation in two parts, first the main body of the riser and contained DP will be cut using a large shearing machine, and then a precision cut will be made with a diamond wire cutter to prepare the surface to act as a support and seal for the LMRP. (Illustrations are below the fold). There are a couple of reasons why this is going to be done this way, and one or two concerns that will need to be watched as the operation continues. (UPDATES At 8:45 am I see that the riser in in the shearing machine, at 9:30 am it appears that they are using a diamond circular saw to cut the choke and kill lines - h/t gel. By 11 am they had the wire saw at the riser, and had started to shear the riser beyond the bend. At 12:50 pm after what may be two attempts to shear through the riser and associated piping the shearing machine has been removed from the riser, and appears to have been taken back to the surface ).
