BP Oil Spill–New Spill Estimates: almost 5 million barrels

New spill estimates released August 2 suggest that 4.9 million barrels of oil (give or take 10%), or 205,000,000 gallons have been released from the Deepwater Horizon oil well.  Of that, they estimate that about 16%, or 800,000 barrels (33.6 million gallons) has been captured. For comparisons sake, the Exxon Valdez spilled 750,000 barrels (31.5 million gallons), and this spill now exceeds the former-largest spill, the 1979  Ixtoc I, which released 140,000,000 gallons.  How they achieved this new estimate is described on the  Deepwater Horizon Unified Command page:

The installation of a new containment cap and the subsequent well integrity testing procedure provided the opportunity to calculate the flow by measuring the pressure at the top of the well as the choke and kill valves were manipulated after the main containment valve was closed to trap hydrocarbons.

Also of interest on the Deepwater Unified Command page was the EPA’s release of the results from toxicity testing on “mixtures of eight oil dispersants with Louisiana Sweet Crude Oil.” The result: “dispersant-oil mixtures are generally no more toxic to the aquatic test species than oil alone.”

On other note, the spill is having an impact as far north as Canada. According to the Ontario Star newspaper, as fall approaches the issue of migratory birds that winter in the Gulf Coast region has come into focus. Of major concern are white pelicans, which just came off the endangered species list, but many other birds could be “flying to their demise”. This is impacting many segments of Canadian society:

Scientists aren’t the only ones concerned about the impact the spill may have on Canada’s migratory birds. Aboriginal groups who have for centuries hunted ducks, geese and other waterfowl to feed their families are urging Prime Minister Stephen Harper and U.S. President Barack Obama to get involved.

The article mentions a program established by the USDA’s Natural Resources Conservation Service which has set up the “Migratory Bird Habitat Initiate” in an effort to mitigate this problem. They are paying farmers in portions of eight states to flood their fields in order to “enhance habitat for migratory birds”.

Oil Spill Disaster – July 27 – more second thoughts

Could Oil Spill Debacle be Fatal to NIMS/ICS? Opinion piece in Emergency Management, July 20. Experienced responders comment on whether or not NIMS and ICS were used as intended for the oil spill disaster response  (Thanks for Bill Cumming for point out this article.)

Risky Decisions led to Oil Spill. July 25, Wash. Post.

The calamity, the evidence now suggests, was not an accident in the sense of a single unlucky or freak event, but rather an engineered catastrophe — one that followed naturally from decisions of BP managers and other oil company workers on the now-sunken rig.

A deeper look at the human toll provides some serious indicators of trouble ahead.  In Gulf oil disaster, cameras can’t capture the human toll
CNN July 26. Some highlights of that story:

* Forget about oil, wildlife, the economy and environment; think about people, communities
* Early signs show rise in depression, domestic violence, substance abuse and more
* “Corrosive communities,” marked by distrust, emerge from manmade disasters, expert says
* Stops along Gulf show how residents cope, or fail to, and what insiders say people need

Oil Spill Disaster – July 23

For Oil Spill Victims, Fair Compensation Requires a Crystal Ball; Gulf Residents Will Need to Predict Future Damages, in The Washington Independent. July 22.

According to a colleague who is doing field work in coastal LA, the incidents of stress and mental health problems are at a very high level. The needs of the local people are huge. I hope Mr. Feinberg can work out something equitable for those hardest hit.

Oil Spill – June 12 – anxiety about effects of spilled oil

BP told to step up containment, WSJ, June 12.

The U.S. has given BP PLC two days to devise a more aggressive plan for containing oil leaking from its damaged deepwater well into the Gulf of Mexico, as tension surrounding the spill grows.

It appears that the Administration and the On Scene Coordinator are applying some pressure to BP to do more and do it faster to deal with effects of the oil spill.
